Convert a snapshot file to memory dump.

A very recently one of our Windows 2012 servers was getting hung, and we were not able to collect dump file. Fortunately, this was a VM and we had an option to convert VM snapshot to a memory dump that can be used for the RCA.

Well, in order to  get this file converted we needed a separate tool named vmss2core

This can be downloaded from Fling link

Once you have downloaded, extract the file named vmss2core.exe.

Open command prompt and change the current working directory to the location where you have the file.

Run the vmss2core tool with the option to create a memory dump.

vmss2core -W virtual_machine_name.vmss virtual_machine_name.vmem

Note: If you are using Microsoft Windows 8/8.1 or Windows Server 2012, run this command:

vmss2core -W8 virtual_machine_name.vmss virutal_machine_name.vmem

This will create a new dump file in same location with an extension of *.dmp, which can be used for dump analysis.

Non-compliant with MS Patches using SCCM

Non-compliant with MS Patches

Found few servers to be non-compliant from the patching team. When checked, found that the patches were getting failed when deployed using SCCM. This issues was fixed by renaming the folder named “SoftwareDistribution” located in C:\Windows\. Further to this found that the service named “Windows Modules Installer” was disabled. Changed it to manual. Now the SCCM pop-up and view updates in Control Panel were populated.

Stop multiple services starting with same name

Stop multiple services starting with same name. Well I was in need to reboot a Windows 2008 server and before reboot all the application services were supposed to be stopped. I had to manually stop all services one by one. After couple of days I was requested to perform the same activity once again. This time I thought to look for an option to stop all services using single command. I found that all the application services names started in same format. Hence, below listed powershell command made my task very easy.

Get-Service | Where-Object {$_.displayName.StartsWith(“ABCD”)} | stop-Service

Note: Replace ABCD with your requirement.
