TIL Move-ADDirectoryServerOperationMasterRole uses legacy name rather than FQDN or hostname

I always have to google this command but I also love how concise it is for moving all FSMO in one command. I’ve run into this problem twice now and I finally noticed the problem when working on a DC that I didn’t originally spin up. I kept getting this response: Move-ADDirectoryServerOperationMasterRole : Cannot findContinue reading “TIL Move-ADDirectoryServerOperationMasterRole uses legacy name rather than FQDN or hostname”

TIL – Today I Learned

Maybe this will be a series but I seem to learn something everyday, so figured in diary style I’ll see if I can share something on a regular basis. I was aware there are different wireless standards for cellphones. Qi and PMA, but the thing I learned is Qi is pronounce, “Chee”. It’s not groundContinue reading “TIL – Today I Learned”
