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 had this question after viewing Outlook 2016 Search Error.

Reinstalling the OS such as the solution linked is not a solution. We have this issue on all our office 2016 machines. I have also tested all the mentioned methods. It appears that turning off the cached OST file is helping. Will check back

Hi experts,
I know this is old NAS server but still needs to support due to some reasons.

NAS Configuration
OS :- Windows storage server 2008 - 64
2 hard drive – RAID 1 configuration for OS (Not Backed up - Want to take backup of this HDs)
12 hard drive – RAID 6 configuration for image backup. (Backed up by tape drive)  

I have failure in one Hard drive (internal OS) and RAID-1 is degraded. To change failed HD i have to open server so before that i want to take backup.   Tried Windows server backup utility to take backup but it is failing on Windows SBS Server 2008 Backup fails  with error code 2155348075 (failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348075.) and VSS (volume shadow copy service error)

We have norton backup exec 2010 for tape backup.

Any idea how to take backup of windows server storage 2008 ? latest Acronis ? or how to resolve standard windows backup error ?

my OS is win 10 pro 64 bit and I had installed the printer drivers from the HP site, whose name is OJ9600_I315-1.exe.  It installed correctly I think, but when I try to load it to use the scanner nothing happens.  Hope the experts can please suggest how to fix this.  Thank u.

Hi all,

I get this error when creating a partition with MS Disk Management in Windows 10:

The operation you selected will convert the selected basic disk/s to dynamic disk/s. If you convert the disk/s to dynamic , you will not be able to start installed operating systems from any volume on the disk/s ( except the current boot volume ). Are you sure you want to continue?

I do not understand why that is.

my OS is win 10 pro 64 bit and my printer is a HP OfficeJet 8600 Pro.  My printer driver got corrupted somehow and I tried to reinstall the software from HP, but I seem to get so many unwanted programs, and not the plain driver.  I have also searched the web and they all come bundled with lots of junk.  Do anyone of the experts know a site where I can download just the program I need for my OS.  thank u.

I need a powershell script that can force logoff multiple users on multiple computers.

Lets say i have a csv file with 2 columns(servername, user)
Example: server= server 1, users=sa.user, sa.user1
server=server2, users=sa.user, sa.user1, sa.user2

Note: Don't need to to know how to get the list of server/s and user/s because I already have a separate script for that.

When using RDP on a local windows OS to a vmware windows vm, which needs the most resources?

For example, the local machine has 16GB/quad CPU and 5 monitors.
The remote virtual machine has 16GB/quad CPU.
The vm host has plenty of resources, memory and vcpu to ensure it does not get maxed out.

The local windows instance is used mainly to access the remote vm via RDP, everything is running on the vm.
Everything works fine, including 2-6 monitors but I am not clear on where the resources are really being used.
The only problem so far is that text is not all that clear when using vms and I'd like to fix that.

The network obviously has some load on it to handle the multiple monitors but where is most of the load beyond this?
On the local machine or the vm?

And, how do I get better text resolution? Text is perfect when the vm is win7 but it is very bad when using win8 vm.

I've got 2 T430s, with an Intel Xeon E5-2630 v4 2.2GHz (10 core), 64 GB RAM, a mirrored 300 GB SAS drive for os & 6 2TB SATA in a RAID 10.
Looking to set up Exchange 2016, network version of Quickbooks enterprise, Trend Micro worry free business security, a remote access server, file & print server, as well as the MS stuff, DC (or 2?) DNS, DHCP, etc.
In complying with licensing, I gather the only role I can have on the host is Hyper-V, which is on my 300GB, would any other VM 'parts" go here, as well?
When setting up VMs, does one VM encompass the OS & data, which would normally be on 2 different arrays the 'old way'?
The two directories for VMs would both be on my RAID 10, correct?
Any suggestions on the best way to spread all my pieces between 4 VMs?
If I've got too much stuff here & would be better splitting between questions, lemme know.
Thanks!

Hello,

I'm trying to deploy OS through a SCCM Distribution point.

I'm receiving the following error:

Contacting Server: x.x.x.x (Gateway: 0.0.0.0)..
No response from Windows Deployment Service server...
Launching pxeboot.com..
TFTP download failed.

We have Tree distribution points each one in different branch, all configured the same way. that mean they are no issue with that because the two others works fine.

- New computer are deployed just fine
- The configuration of DHCP options on the distribution point is correct
- the WDS is running on the distribution Point


When re-deploy an old computer I receive the above error.

- I cleared the PXE advertisement on the Computer on SCCM
- Delete the computer from SCCM
- Delete the computer from ADDS
- check if any computer with the same MAC address exist in SCCM database, NO record found
- Check the Logs on the Distribution point (smspxe.log), all what I found is:

<![LOG[CC:52:AF:49:6C:95, 4848AB34-1EBA-11E2-B7B9-23D705C62D00: device is not in the database.

My HyperV host is licensed with 2012 R2 Standard, and my first attempt at installing the guest OS of 2012 R2 didn't go well, so I deleted it and started over. (I don't remember having to activate that one)
I have this VM all set up and ready for production, but it has a notification that it needs to be activated. Did I do something wrong? It will not activate with my original key either...

I'm getting an error when my backup computer boots up under Windows 7.

The message I get is: "Failed to connect to a Windows Service

Windows could not connect to the System Event Notification Service.
You can review the System Event Log for details about the service
that didn't respond."

I've brought up the Event Viewer but am baffled about how to use it to get this part of the OS running.

Does anyone out there know?

I have a box that I configured to use MD RAID during the install process for the OS and boot drive. It's this weird /dev/md0p# structure that confuses me.

The installer produced /dev/md0p1 (/boot), /dev/md0p2 (/var/lib/mysql), /dev/md0p3 (/), /dev/md0p4 (extended), /dev/md0p5 (swap). I noticed it did this for all physically installed machines from the CentOS 6 DVD.

How do I increase the size of the /dev/md0p3? I need this root partition to be expanded. I feel like I need to delete the /dev/md0p3, /dev/md0p4, /dev/md0p5 partitions and then create a new one for /dev/md0p3 with the extra space. I don't care for p4 and p5, because they don't contain actual data. I can create them after the fact.

I am confused on the order of deleting partitions and adding the space in respect to /dev/md0. fdisk -l shows the drives /dev/sda, /dev/sdb and then finally /dev/md0 with all of the sub partitions.

Hi all Guru
out there,
I m tryiing to complete my development trial with this php tools. it seems relatively easier to learn compare to other language.
after i had tried a few examples. I was hit on the death end.

https://netbeans.org/kb/docs/php/wish-list-tutorial-main-page.html

1. I m using my mac machine to run the netbean. the whole program just stop when i reach lesson 3. after i had tested a few round. from
I was thinking could it be folder permission. I had tried with changing my properties of htdoc folder from my mamp. it show nothing on my chrome. worst still. the whole chromes throw me nothing on it screen lead me no way to find where to troubleshoot.

2. I install a VM with Windows 8.1 with similar netbean. at got another set of problem which said.
Fatal error: Access level to WishDB::__construct() must be public (as in class mysqli) in C:\xampp\htdocs\wishlist\Includes\db.php line 107

ok. after i had research a few try under w3school with object construct. that logic seems fine.

3. I m researching thru google. seems ubuntu work seemlessly. so i install ubuntu os and install netbean. i have the similar no error prompt.

I brought that piece of example to one of my friend hosting where it had the whole cpanel, php and my sql service. and woala. that piece of code indeed working with CRUD result.

that limit to OS issue. anyone could give me a hand. so i can use this to move on to develop my dissertation project.
be it mac (Netbean, …

For the past month I have been chasing an annoying problem. Something is crashing the mouse driver on my Win2k8 server, causing the mouse (but not the keyboard) to freeze. I have been remedying this by restarting in Safe Mode and deleting the USB Hubs in Device manager. The OS then reinstalls them and all is well until the next time. Recently, I have begun to suspect Google Chrome as the cause. I notice that I'm usually working in Chrome when the freeze occurs. This last time I noted that I had 6 tabs open and TaskManager shows 20 instances of Chrome open using a total of 1.9 GB of memory. With 8gb of memory installed, is this a problem? It didn't used to be. Do I have a memory leak and if so, what can I do about it? (I already uninstalled and re-installed Chrome)

I am getting the following error when trying to run gdb on my Mac OS, on an executable.

Unable to find Mach task port for process-id 469: (os/kern) failure (0x5).
 (please check gdb is codesigned - see taskgated(8))

I followed the instructions online to get a certificate set up. Then I ran
codesign -fs gdb-cert "$(which gdb)"


Still getting the same error.

Ideas?

A Windows 10 computer displays the following prompt when Windows loads "This computer is configured to require a password in order to start up. Please enter the Startup Password below" (see the screenshot).

The user has forgotten the password.

We have already tried several startup options including booting into safe mode, performing repairs, etc. but have been unable to get past this screen.

If we click on OK nothing happens and if we click on the Restart button then the computer restarts.

What can be done to bypass this Startup Password or what can be done to uninstall the program or whatever else is causing this pop up to appear?

I have two pfSense boxes in HA sync running the latest build (2.3.4-RELEASE amd64).

They work fine, acting in a master/slave private IP failover setup, but the XML_RPC connection over the HA link keeps failing with the following error:

A communications error occurred while attempting XMLRPC sync with username jblokes https://slave.firewall.ip:443

The log on the master unit shows:

Jun 14 00:45:15    php-fpm    54775    /rc.filter_synchronize: New alert found: A communications error occurred while attempting XMLRPC sync with username jblokes https://slave.firewall.ip:443.
Jun 14 00:45:15    php-fpm    54775    /rc.filter_synchronize: A communications error occurred while attempting XMLRPC sync with username jblokes https://slave.firewall.ip:443.
Jun 14 00:45:15    php-fpm    54775    /rc.filter_synchronize: XML_RPC_Client: Connection to RPC server slave.firewall.ip:443 failed. Operation timed out 103

Open in new window


As a result of this, the interface firewall rules aren't being synced to the slave unit.

After googling the above error, I found that there used to be a bug in pfSense sometime ago, but I did not understand whether the fix for that isn't already included in my OS build or it's something I need to patch manually?

I have a domain member computer.  The computer is not currently connected to the domain because I took it offsite so I could attempt a bitlocker install over the weekend.  When I try to run bitlocker on the OS drive it states that administrator must set the "Allow Bitlocker without a compatible TPM" option in the "Require addtional authentication at startup" policy for OS volumes.  I enabled this option is the systems local policy but it still won't get past this issue.  What is the problem?
