FYI I had the issue that I needed a name change without reboot AND running PsExec for another user session on the same machine afterwards. I got this Error: Creating key file on $newComputername. The user name or password is incorrect / The network location cannot be reached.

Fix was to add the following lines to rename.ps1

# Restart service to have PsExec working after name change; wait 5 seconds to be safe
Restart-Service Server -Force
Start-Sleep
