PDM Login Troubleshooting

Out of the blue (sort of) users cannot log in to our vault. I’ve checked everything I can think of but cannot find the problem. I say this was sort of out of the blue because the troubles started not long after we migrated all our users to a new domain. The servers were moved to the new domain a couple months back, and we had both domains in use, with users still on the old domain. Every now and then a user would get a failed login and they would have to add the domain name before their user name on login and the problem would be gone. Sometimes the old domain was needed, sometimes the new. Whatever. Fast forward to now and no one can log in except the master ‘admin’ login. I’ve moved this vault to new domains and new servers multiple times over the last 20 years with no issues until now.

I’m looking for anyone who has an out of the box idea about what might be going wrong, or novel ways to troubleshoot it.

Are you using Active Directory accounts for access to your PDM vault, or are you setting up users from within PDM itself?

They are Windows accounts and always have been.

One thing I keep seeing recommended is using a dedicated domain account to run the archive server service instead of the local system account. We’ve never done this, and have never had a problem until now.
