We are operating on a Windows 2003 AD domain, and we have about 20 users on this single domain. Nothing elaborate, and simply a straight forward simply AD domain setup. All users are setup identically in that they are part of the same security groups with similar access to network drives, etc.
Of all these users, I have one account that keeps getting locked out for no apparent reason. We've tried resetting her password several times, but after a week or so her account suddenly becomes locked. Just now while she was accessing a MS Word document on a network drive that she accesses all the time, she was locked out with a popup stating:
"Restoring Network Connections: An error occurred while reconnecting W: to \\server\share Microsoft Windows Network: The local device name is already in use. This connection has not been restored."
She has 5 other network drive mappings and they were all locked out. They all point to the same file server as well. I could not create new drive mappings either, so we rebooted. She was able to log on to her computer, but the drive mappings derived the same error. I checked her user profile and her account was locked. I unlocked it and all is well.
This sort of problem repeatedly happens with this user. It happens at any given moment while she is in the middle of working. I even went ahead and swapped out her computer and setup a new local user profile. I thought there might be some sort of corruption with the local profile on her original machine, so I went ahead and swapped out computers with another user. The lockout issue happens with the new computer as well. The next step is creating a new AD user profile. Do you have any idea why a user profile suddenly locks out a user when they know their password, the reset password period has not expired, and no virus or malware is detected?
