r/WindowsServer

I had one recently where a small config issue turned into hours of troubleshooting. Everything looked fine on the surface, but something in the background was misconfigured and it just wouldn’t behave the way it should.

What made it worse was that all the usual fixes didn’t work, so I kept going in circles before finally figuring it out.

It got me thinking… a lot of Windows Server problems aren’t actually “big,” they just become time-consuming because they’re hard to trace.

Curious what others here have dealt with. What’s one issue that looked simple but ended up eating hours (or even days) of your time?

PS C:\WINDOWS\system32> nltest /sc_verify: [domainname]

Flags: 40000080 Authentication Service: Netlogon

Trusted DC Name

Trusted DC Connection Status Status = 5 0x5 ERROR_ACCESS_DENIED

Trust Verification Status = 5 0x5 ERROR_ACCESS_DENIED

The command completed successfully

I have an old VM running on an XCP-ng server that uses HDD storage. I took a backup using Veeam Backup & Replication and am now trying to restore it on a Proxmox VE server with SSD storage.

I was able to successfully restore a few VMs by selecting the appropriate BIOS type, SCSI controller, and IDE disk where needed. However, this particular VM is not working.

Even when the restore process completes successfully, the VM does not boot into the OS and shows boot-related errors.

I have very limited experience with cross-hypervisor migrations, so I’m not sure what I might be missing here. Any guidance or suggestions would be really helpful.
