Operating Systems





Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

I replaced a computer, with a new model, and the new model came with a different docking station, but the docking station does not have a DVI connection.
I will try connecting the laptop directly to the  LCD and see if it resolve the problem
I will also try a display port to VGA adapter.
I was not able to get the resolutions on both LCDs to match since one is smaller than the other.
The BIOS is already updated and all the latest drivers have being installed.
The device will receive new Windows Updates soon.
OS is Windows 10.

Challenge: I have two LCDs with different sizes, when Outlook is moved from the smaller LCD to the larger one, it does not maintain the font size.
I will have to configure Outlook to open in compatibly mode and set the resolution for it, I am confident that will address the problem.
My other idea is to purchase an DVI to HDMI adapter, since VGA and DVI are different technologies.
The docking station only has an HDMI, display port and VGA adapter.
The LCD that has the problem only has a VGA and DVI ports.

I may have to reach out to the manufacture of the LCD for their input.
The other thing I can try is to install the latest video drivers directly from Intel and execute driver verify on it.
The other thing I was thinking of is to lower the hard accelerator  on  the LCD, but as of this writing, I have not researched that, on Windows 10, I know you can change the graphic libraries on Windows XP.
I have to compare the video card on the …

I need to be able to share a printer when a computer is connected to the VPN.
My theory is that  the printer will need to be shared, before it can be printed to, when a VPN connection is established.
The OS is Windows 10
My other ideas is to uninstall the printer and install it when I am connected to the VPN.
I imagine there is a solution to this challenge.
I do not recall the other steps I tried, but I believe the one solution to the problem is to configure a Cisco ASA.
I was also thinking that I will have to enable the wireless printer's IP as an exception on the firewall.

Maybe I need to create a script with Powershell, to first configure the printer to print to a file then send it directly to the print queue.
Hello Experts,

We have Dell R610 servers in our network, last few days i am getting unexpected server reboot issue, i try to find issue but unable to find out.
please help me out i am attaching 2 servers log files.

OS - Windows Server 2008 R2 Stranded SP1
I need to run some 32 bit legacy software and some old hardware (Scanner) that will not work with Win10.

Can Windows 7 32bit and XP be installed on newer PCs ?
If Yes ... How new ?     ....... How about an Intel i3 ?

I know that anything above 4gig memory is wasted on 32 bit systems.

(These PCs will not be connected to the internet or my LAN so security will not be an issue).

I have a client who encountered a completely frozen Windows Server 2008 R2 this past weekend.

Server was unresponsive via RDP or direct console. No user interaction could be performed. System was non reponsive
to any attempt to open task manager and terminate processes.

A forced shutdown was required to regain control.

No network intrusion, AV or other issues were found.

The unit is a PowerEdge T420 with iDrac.

I have looked at every log in the event viewer and can find nothing regarding this issue. I've filtered the event logs to 24 hours on either side, no listing of anything.

Is it possible the iDrac could manifest such an issue?

I come from more of a log file and Unix background and wanted to know if there is a way to dig deeper into the OS, similar to /var/log/messages, kernel panics, etc.

Any assistance is welcome.

In Azure  when I create a Windows machine it let me choose the OS version but not all. Like Windows 2012 it just give Windows 2012 Datacenter or WIndows 2012 R2 Datacenter. Why just Datacenter version?

Hey all,

I have a wierd one here.. I have a client running 2012 R2 - this runs their file & print sharing, Active Directory and backup software. The IT officer that I deal with has been asking me to help him with an issue, which is the server goes offline and has no connectivity. The server remains on and the OS is in tact but the network card says "no internet" unidentified network.

DHCP is running through the firewall which is (Default Gateway / DHCP). Long story but we will leave that.. This firewall is around 8 years old btw so it could be the culprit and will be providing them with a test unit to see if we can narrow down but I haven't given you the curve ball yet.. wait for it.

Things we have tried;
  • Checked error logs at the time it drops and nothing pops up at the time of the drop out.
  • Testing all cables running from server, Tested OK.
  • Tested connecting to the Firewall LAN port, tested OK.
  • Swapped NICS from NIC4, to NIC3, NIC2 on the server and still no go.
  • Checked all the IP config is ok. (server) / / (gateway) / (DNS)
  • From a client's computer, provided a static IP address. Cannot connect to server or gateway so it does not see the network at all which is odd
  • We have swapped out to a new switch as a test which we will leave there for the time being
  • Checked DNS services, forwarders & entries are correct on the server
In Mac OS Mojave, I'm contending with lengthy delays in applying changes to network interfaces. Sometimes 60 seconds to apply a change to Service Order (i.e. move Ethernet ahead of wifi) or to configure a Static IP address.

The Network Pref window also appears blank when first loaded and takes a full minute to populate. (I have many network configs in my list)

When preparing, testing, and troubleshooting networks (a big part of my job) this is really bogging me down. Never saw this before with any previous release. Always in the past changes are instant with no "apply" delays.

This symptom continues after installing 10.14.2. I've also tried:

- Resetting PRAM
- Resetting SMC
- Reinstalling MacOS using Recovery Mode
- Removing all 3rd party apps that could interfere
- Booting with Shift key down - no performance improvement

My last move is to wipe the machine and recover from backup, discarding the network config option. However since I have so many VPN configurations this is a really big deal.

I'm hoping someone has some other suggestion.
I have three Toshiba Encore 2 WT8-B tablets.   32 bit 8.1 Connected is the current OS
the tablets won't activate Windows with the imbedded keys.
Microsoft says the keys have been used too many times...Toshiba support blows.

so, if I want to upgrade Windows to get out of this mess....what is the proper ISO to upgrade a Windows 8.1 tablet to windows 10?

another option is trying to find a good key to enter - so, what kind of Windows 8.1 key works with Connected?

...this is a pain in the neck I just want to go away!
Good day.

I need some advice on Microsoft licensing.

My existing file server VM runs on a Server 2012 R2 Datacenter host. I want to create a new file server VM that runs Server 2016, which will reside on the same Server 2012 R2 hypervisor.

According to my Microsoft VLSC portal, I don’t have an available standalone license key for Server 2016. I only have SA keys for Server 2016 Datacenter and Server 2019 Datacenter.

Is there a legitimate way for me to install the OS to Server 2016 based on my existing licensing assets?

Upgrading my Hyper-V cluster to Server 2016/2019 is not currently supported, as it is an HPE Hyper Converge platform. I will upgrade the hypervisor once HPE’s dev team has developed a migration path.

When responding, keep in mind that my path needs to be absolutely legal and ethical; nothing is worth jeopardizing my organization. I am hoping that an expert can tell me that Microsoft intentionally created some sort of loophole to help people in my situation. Am I just naïve?
I am currently with Ivanti formally known as Shavlik patch management.  My 3 year is about to expire, what I was paying for 3 years is now what I will have to pay for 1 year so we can not continue with Ivanti.   Does anyone have any recommendations on a patch management system that has a reasonably  price structure?

I'm sure this this a very simple answer, but I'm having trouble finding it. It's one of those situations where I ask "What time is it?" and the reply I get is how to build a clock instead of a simple answer.

I want to change folder settings in Windows 7 and 10 to display certain settings for ALL folders I open.

For example:

 Screenshot 1
note that I have selected the "size" option to be displayed for files in this folders where that option is applicable. and also note that I have selected the "file type" option as well.

Is there a way to set these options to show for ALL folders all the time in both operating systems? AND--especially important--when I plug in a n external drive and look at files on it, will those options also apply automatically to those files?
I am running the Mint 19 Tara OS on my laptop and I have an issue with my startup (boot) sequence.  Something is telling the system to encrypt my swap partition but I do not have a swap partition...  The "job" tries to run but it times out and fails.  It repeats itself numerous times during the boot sequence and wastes a lot of time during startup.

I need to identify what application is trying to run this job and why?  Then I need to figure out how to stop it from occurring.  I have no need for encryption on my computer at this point in time.  I am attaching a copy of the boot.log file so that the event in question can be viewed & identified.  It starts out with the line: "[* ] (1 of 2) A start job is running for dev-mapper-cryptswap1.device (8s / [** ] " and it appears that it is trying to encrypt two drives but I am not sure.

I'm attaching the boot.log file, any help with this would be appreciated.

i am trying to run virtualbox to power-up VM on Private Cloud but unable to start the VM with error of shutdown the WIn 10 Guest OS each times when trying to Power-up the Virtualbox VM. Thanks

VB Ver 5.2.22r126460
Win 10 Enter OS => 1803 (OS Build 17134.407)

My network consists of two HyperV machines HyperV1 and HyperV2
HyperV1 hosts Server1 and Exchange1
HyperV2 hosts Server 2 and Exch2
DFSR was installed and working well

Server1 OS is on a virtual disk on C drive and the data is on a virtual disk F drive
Server2 is on a virtual disk on C drive and the data is on a virtual disk F drive
Server2 paused with lack of disk space and has refused to start
I have seized fsmo roles using ntdsutil, and all seemed to go well

Now when I attempt to log onto a workstation, the roaming profile is not found.
When I log onto server1, and attempt to open active directory and computers I get the error "naming information cannot be located because the specified domain either does not exist or could not be contacted.  Contact your system administrator to verity that your domain is proper configured and is currently on line"
When I try change a directory server, and use the domain name, I get a Domain controller could not be contacted

I need to get server1 back up and then consider options to rebuild or restore server2, but need the network functioning
Anyway we can find info on SFP of HBA cards like vendor /speed or some diagnostic report from linux OS
I cannot get some of the computers on my Domain to report to WSUS. I've tried many things including (taken from other sites):

1.      Press Windows key + Sand type Command Prompt (Admin).  
2.      Type these command and press Enter after each command:  
o      net stop wuauserv  
o      net stop cryptSvc  
o      net stop bits  
o      net stop msiserver  
1.      Rename SoftwareDistribution and Catroot2 folder. Type these command and press Enter after each command:  
o      ren C:\Windows\SoftwareDistribution SoftwareDistribution.old  
o      ren C:\Windows\System32\catroot2 Catroot2.old  
2.      Restart the BITS, Cryptographic, MSI Installer and the Windows Update Services by typing these command and press Enter after each command:  
o      net start wuauserv  
o      net start cryptSvc  
o      net start bits  
o      net start msiserver  

•wuauclt.exe /resetauthorization
•wuauclt.exe /r /detectnow
•wuauclt.exe /reportnow

The computers just will not report and therefore, won't download and install updates.I also noticed that no matter how many times I start the BITS Service, it keeps stopping again. It is very frustrating how much work is involved (client side) to keep computers talking to WSUS. Has anybody got any useful tips?
One of my Techs ran a sfc /scannow  and it came back with a bunch of error which I do not have and according to her they were repaired. Once the user rebooted the network adapters disappeared. I ran a few fixes that I found via google but they did not work. The user did a refresh under the network and sharing/adapter settings and it gave this error " The network connections folder is unable to retrieve the list of adapters." Any ideas.... google is failing me today. :(

I did fail to mention they are under device manager though.......

What in a Profile would turn off the calculator in Windows 10
I have a OU that has a minimal profile and the calculator works.
Every other OU makes the calculator disappear

I know windows has problems with the calculator because of the app store.
Why would one OU not care about contacting the app store and just work.
I have a couple of systems here at my work that got the windows store and other apps (calculator) uninstalled.  I have been trying to run the powershell commands I have found in order to reinstall those but nothing seems to be working.  Other than reinstall the OS is there anything else I could try before doing something more destructive?  thanks.
Has anyone any knowledge of a way to pass error codes from a Windows Server Backup in Server 2012/16/19 to a batch file.

Scenario - for sites that just want to run Windows Server Backup as their only backup method, I have a batch of XML files I import into Server 2008R2 Task Scheduler.  These file contain a list of responses to Return Codes from Windows server backup and email me + the client the details
  • When an unrecognised drive is attached error 561 is generated in the event log
  • Task Schediuler generates an emai warning me they have used the wrong drive
I have ones covering things like low disks space, backup succeed, backup fail, no drive connected.....

With Server 2012 and 2016 I can generate the emails easily enough but want to pass the error code to the batch/script, so that the subject and body of the email is generated based on the error code.\

Have spent a few hours playing with various variable from the OS but cant find it...any clues
Need some help with Jmeter .

Environment: Apache Jmeter 5.0 , Java 1.8, Mac OS High Sierra 10.13.6

Problem outline:- Post call not getting 302 response with Location header(redirect) instead get 200 response without Location header

The problem here is in Jmeter but same works in Postman.    In a Jmeter thread group I have cookie manager and couple of Get and Post calls. I set to save the cookie in user.properties file.
 Scenario:- Login
1) first do GET ( call with some query parameters) / login endpoint  will give  response cookie and csrf-token with 200 then next
2) next do POST with form data (  in xxxform url encoded with csrf-token from get response ) + Cookie from get response from at / login endpoint  should return 302 with token is the expected result but getting 200 instead with no redirection  in Jmeter. In Postman able to get the desired results.

When the same is replicated in Jmeter with same setting as performed in Postman results are not as expected

Errors in Jmeter are:- 404 with location header missing or 200 with no Location response header

But not 302 with Location response header

With how many different combinations attempted.

Attached my sample TestPlans and Post request. Have also tried to place form data in Body instead in Parameters tab but have the same result.

Thanking in advance! Appreciate anyone who could share their thoughts and rescue from this current issue.

i can't resolve the hostname like google.com or private cloud hostname as well.


Using Microsoft Access (2003)
I have a form with a text box called PicFileName and an Image Control called PersonImage
The intent is that the following code will cause .jpg (picture) to appear in PersonImage, without the .jpg being embedded in the table behind this form (in order to save space)
The following code accomplishes this perfectly:

Dim strPicName As String
Dim strPicPath As String
Dim strSource As String

strPicPath = C:\Pix                 C:\Pix is the folder containing the jpg
strPicName = ABCD.jpg       ABCD.jpg is the filename of the picture

strSource = "" & strPicPath & strPicName & ""              in this case it will be C:\Pix\ABCD.jpg

If Not IsNull(Me.PicFileName) And Me.PicFileName <> "" Then
    Me.PersonImage.Picture = strSource
End If

As I said this works perfectly in all computers on my LAN, EXCEPT for ONE which returns an error 2114 saying that this code is not supported OR the jpg is too large!  I have reduced the size of the .jpg to a few K, to no avail.

ALL COMPUTERS ON THE LAN USE THE SAME OS (Win 10 Pro), AND THE SAME VERSION OF ACCESS, AND GET THEIR JPG FROM THE SAME FOLDER,  and the above process runs perfectly for the last six years!!

QUESTION: What needs to be adjusted in the one computer where this is not working?
