If you have an old fileserver name that you want to retain on your new server or simply would like to add a new name to your fileserver, these two lines of code might help you.

NETDOM COMPUTERNAME oldFileServerName /ADD newFileServer.contoso.local

ipconfig /registerdns

DNS CNAME is not needed, the computer account is going to add the entry in Windows DNS by itself.

Microsoft seems to add new bugs more than features to new Windows Server releases. If you are having a static picture after logon in Windows Server 2025, this GPO might help you. We do not really know why it happens, but this was a solution that worked for me.

Computer Configuration > Administrative Templates > Windows Components/Remote Desktop Services/Remote Desktop Session Host/Connections > Select network detection on the server > Use both Connect Time Detect and Continuous Network Detect

Some have suggested to set this configuration to “Turn off” but that did not help me out.

If you do not know which program or service is deleting your files or folders, ProcMon will help you do this. Firstly download it from http://live.sysinternals.com.

Once the program is executed add a new filter Operation is SetDispositionInformationFile

Afterwards add the file or folder that you want to monitor. Path contains FOLDERNAME. You can also insert the whole path to the folder. Afterwards hit ok.

Also, to avoid using a lot of ram, configure “Drop filtered events” in case ProcMon will run for some hours.

Now patiently wait until the event occurs. Enjoy!

Storage Sense is a new feature that came with Windows 10 and tries to delete temp folders or unused OneDrive data. The feature is good but sometimes some programs, probably not that good designed programs create files in the user’s temp folder and do not function properly after those files get deleted by Storage Sense feature.

So in order to disable the feature, here are some registry keys and GPOs that might help you:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\StorageSense\Parameters\StoragePolicy
DWORD 04 Value 0

Group Policy:

Computer Configuration > Administrative Templates > System > Storage Sense > Allow Storage Sense Temporary Files cleanup and set to disabled.
