Ok, this is a strange one that I'm having trouble replicating letting alone solving. I have a user who uses two computers (both XP sp3) on the domain with a roaming profile. She has no problems on her personal computer but occasionally needs to use a shared computer. On this shared computer she is sometimes (~once a week) unable to login with the error message "Username or password incorrect. Check username password and domain and try again."
I've checked when this happens and her username and password are indeed entered correctly. Now the strange part - if someone else logs in to the computer (which so far always works) and then logs out she is able to log in after that.
This problem began after a recent and long overdue password change.
I've tried to replicate this problem after a reboot, or after another user logs out to no avail.
Any suggestions on troubleshooting or replicating this one? Anyone experienced something similar?
