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.

We have one client that has a SBS2011 with Exchange 2010.

One of the users decides they want to use a mac in the environment for external use and internal.

They use the built in email app that buit into the ios OS.

I have added A records on the server DNS for remote.domain.com pointing to the exchange servers IP address.

DO I need to add anything else because it still does not work.

I have the internal and external server settings on the app to both remote.domain.com

I believe Windows latest update caused sleep mode to reboot the computer.  I'm on OS Build 17134.48 which introduces "task view" among other things.  Has anyone see this issue?  Also, I'm trying to revert back using a Windows recovery point.  This never shows more than one recovery point.  How do I enable more or older recovery points?  Also, remind me how to uninstall this new Windows feature update.
I hope you can help.  I have a DPM 2016 (Version 5.0.342.0) built on Windows Server 2016 fully patched OS with a HP LTO 7 Ultrium 15000 external Tape Drive attached.  My issue is the Tapes are not using the Compression and I have now reached the native 7TB capacity of the tapes.  
I have the Tape compression enabled on the Protection Groups but it does not appear to be sending the compression instruction.  I have also ensured that I am using the latest firmware and drivers for the LTO 7 drive.  Does anyone know if DPM 2016 can provide compression on the HP LTO 7 Drive and if so what may I be missing on getting this work?  Many thanks for any assistance provided
I have 10 new HP Desktops with Windows 10 that I want to make a master image for to make deployment faster.  What software do you suggest to accomplish this? We do not have volume licensing.  Will this be an issue?

Is there a way to wipe a Macbook clean without removing the OS or is that not a concern...that is, can you simply download an OS for free?  Basically I want to get a Macbook ready for a new user.
Failure with TimeMachine backups. OS Problem?

I had an external disk fail to complete the Time Machine backup with no error message, that I can find. I eventually started afresh using Disk Utility. BUT it still failed!

On another front, I have been told I should re-install the underlying OS on my machine, which I am afraid to do without a current backup!

I do use Cloud based Carbonite, but do not feel safe until I have a hard external backup disk.

The reason I was advised to re-install my OS was that while using Finder, incrementing through my pictures, sometimes the cursor jumps to the end of the list. I did try some small instruction on Mac start-up, if I recall, that involved holding down certain keys.

There was a second instruction, but I sadly can on longer find that post.

So, the last suggestion was to re-install the underlying OS. And it seems I am there right now.

Can anyone suggest a nest step for me?

I can not make a current backup of my machine.

Hi Team,

We use USB Buffalo DVD drives in our environment on our Wyse THIN OS 3040 devices. We also installed latest driver on citrix servers, still when we try to connect to citrix session it showing an error in device manager as STATUS _DEVICE_POWER_FAILURE(This device cannot start. Code10). Tried installing latest drivers but still problem remains same.

Is there something i am missing, or any other driver need to be installed? Can someone help me here.

Thanks in advance, your help is much appreciated.
Windows 10 hangs at blue cursor circle. At first, I knew this to be the 1803 update, and did a system restore and shut off all pending updates. However, now anything that installs updates (Adobe, autodesk, etc) gives me the blue hanging circle of death on a black screen. How can I fix this permanently?

I have tried start up repair, installed new Windows from scratch. Nothing seems to fix this issue.

SOMETIMES, if I restart the PC while pressing Shift+F8, it boots normally.

what are all the ways to find pdf files

I am asking someone to search their computer(s) for me to find pdf files
This was setup in the past but the person that set it up is no longer with us and since we have upgraded the OS  to 2012 R2 and it was setup on 2003 TS. We got rid of the 32003 and added 2 new terminal servers with 2012 R2

We need to setup the following for users,,,,, Multiple users that log into one just one account and from that account they have access to their emails through a drop down tag, the dropdown has all of their names on it. When they choose their name it will pop up and ask them for a password

So basically we need an icon setup on the terminal server so that once the users login with the same single account, they can then click on the mail icon and see there name and select it to and have it prompt them for their password to their email account in exchange.

Does anyone know the steps on how we can set this up?

I am looking to set up a Linux virtual server in Hyper-V.  Where is the best\legitimate source of getting the Linux OS?


We have ESXi 5.5 on which I want to automate the deployment of an OS (W10), I created a VM which should boot from a DVD automatically.
It does that, but not before I do 2 manual actions (see screenshot below). How do I configure the VM to do this automatically?
This worked fine with normal BIOS but since I have set it to EFI, it does not work anymore.

Note: first time it should boot from DVD, but only first time (since after that it should load the OS which is being installed):
Good day-
I have an Ntfs volume from a failed server 2003 (not a typo). The volume was RAID1 and a member file server.

Ntfs permissions are keeping me from accessing previous versions - although I can see the previous versions thru explorer.

Any tools you can think of or am I dreaming?
can an installed .exe file on windows os see all my key strokes
I have a custom made .exe file that appears to me to run correctly
but may have additional secret permissions

by installing any program
could a keylogger be built in

dont just tell me to run virus scan
Best Solution for Upgrading Windows 7 (Of all different versions) to Windows 10 Education.

Unfortunately we don't have a server were we can remotely connect to do have an image pushed down so I think we are just gunna have to go to each device and install Windows 10 manually that way.

But I wanted to reach out to you all and see if there was a better solution. Work smarter not harder!

Our goals are to: Upgrade Windows 7 (Of all different versions) to Windows 10 Education. With no data loss. We do have a way for users to back up their documents but that doesn't stop them from saving stuff to the desktop.

We would also like a custom image where the license key is already in the image. (Not sure how to do that. We do have a volume licensing agreement so one key can be used on X amount of devices)

And lastly is there a way to have certain programs pre-installed already like Microsoft Office 2016 in the image or no?

Thanks so much for taking the time to read all this.
What are the steps to directly upgrade Windows 8.1 to Windows 10 so that all programs, user accounts, and customizations will remain in place after the upgrade to Windows 10 completes?

Is this as easy as downloading the Windows 10 ISO file into Windows 8.1 and then running the Windows 10 setup file within the Windows 8.1 OS and following the prompts to upgrade?
Every time i capture a new image via Windows Deployment Services it asks me for what Administrator password will be set during deployment.
After the image is uploaded to MyImageGroup, i then export it as a custom image and import it into Deployment Workbench as an operating system and then set up a task sequence.
If I look at the properties of the task sequence and click on edit unattend.xml from the OS info tab, the password is set correctly.
I have confirmed this by opening the file from d:\deployment share\control\1030\unattend.xml
When i deploy the image, and reboot the PC after deployment, the local Administrator account is set to a password I used to use a long time ago and not what I set during capture.
Where else would it be pulling the old password in from?
I do update the deployment share each time I add / amend something
Some users report an inordinately high number of account lockouts.  Review of the NETLOGON service activity on the domain's PDC emulator shows a large number of bad password errors from computers that do not exist on the network, sometimes involving accounts that don't exist or are no longer active.
In order to track down the sources of these authentication attempts, we need to store copies of the Security Event Log on the domain controllers. This will both alter the data being recorded to better target interesting events and replicate that data to another server for further analysis.

Can you please then assist to have to create and link a GPO that configures audit logging and event forwarding on all domain controllers and any selected servers.

What kind of information and data is contained within the CBS logs (found within the C:\Windows\System32\Logs\CBS folder)?
Does anyone use Essentials anymore and if so why? What are the benefits for a small company of 10 or less people.

I've been using Server 2016 Standard more often for small businesses with 1VM as the PDC and the 2nd as Exchange. Have a client already on Office 365 thinking Essentials is the way to go. A concern is they may need an additional server, am I correct Essentials doesn't come with any VM's options and we would have to purchase another server?

Client also likes the remote access they had prior in SBS, this is an add on, correct?

Finally, am I correct and the 25 user CAL's are included in Essentials?
Lenovo E560 w/ Samsung 860 500GB SSD.  Laptop boots fine about 10 times in a row and then blue screens and won't recognize the 860 as a boot device. The OS is still there. I've updated all the firmware and drivers. Anyone else have this issue?
looking to connect to rds broker via hp thin client t510 (windows CE 6.x)

When I fix people's computers 4 times out of 5 it's because operating system files get corrupted. I understand that can be prevented by using a filesystem built for data integrity. I am unclear which disk format to use and why.

After some research it appears that the only option for Windows is ReFS but that is focused on enterprise and can't be used for the OS disk, so Windows doesn't really have any options yet as far as I can tell.

For my Linux machines it looks like BTRFS and ZFS are both options but I'm not sure which one to use or if there are any better options. I tend to run Arch based machines but am comfortable and happy with Debian options as well.

From what I can gather about Apple they use a combination of hardware ECC and APFS to ensure data integrity but is that enough or should I use another nix based format like ZFS?

What are the downsides if any to these data integrity focused disk formats other than potentially performance?

Edit: Let's assume that the system is not impacted by malware and already has a working UPS with graceful shutdown.
