On this page I will collect commands and short snippets on problems I encounter

Windows

Problem: “The trust relationship between this workstation and the primary domain failed”
Fix: Reset-ComputerMachinePassword -Server DomainController -Credential DomainAdmin

Active Directory

Running a domain controller on Hyper-V that is a member of the same AD domain. This can cause system clock to drift. To mitigate that you should force the DC with PDC Emulator role to sync from an external source and stop the Hyper-V time sync service:

1
2
3
4
w32tm /config /manualpeerlist:se.pool.ntp.org /syncfromflags:manual /reliable:yes /update

Restart-Service w32time

Stop-Service vmictimesync

Get-Service vmictimesync | Set-Service -StartupType Disabled

It is also possible to remove time sync in Hyper-V settings for the VM but, at least in older versions, that may cause the VM to start up without knowing the time.
