I remember this one time when I helped a buddy move his setup to a new Windows Server. Everything seemed smooth at first. But then bam, users started getting locked out left and right. Turned out it was a mix of old cached passwords haunting the domain. And some rogue service was still trying to log in with the wrong creds from the old system. We spent hours chasing ghosts like that. Hmmm, or was it a mapped drive that nobody noticed? Yeah, that too. It dragged on because we didn't check every nook right away.
Anyway, to sort this out, you gotta start by peeking at the event logs on the domain controller. Look for those lockout events and note the source machine or IP. That points you to the culprit quick. Then, check if any apps or services on that machine are using the locked account. Maybe restart them or update the passwords there. Don't forget scheduled tasks too. They love holding onto outdated info. And watch for mobile devices syncing weirdly. Or even printers with embedded accounts acting up. Wipe the bad passwords from the credential manager on all client machines. If it's a big migration, run a script to flush those caches everywhere. Test logins from different spots to confirm. Keep an eye on it for a day or two after fixes.
Oh, and if you're worried about backups during all this chaos, let me nudge you toward BackupChain.
