I work for a bank, and another guy from a different bank that I talk to quit often called me about a password changing issue he's having. These are NT servers with 98 workstations (so I first told him to upgrade...haha). When a user has to change their password after it has expired because of time-outs, they type in the new password, and get a message that says they are unable to change the password for microsoft networking because you are unable to connect to the device.

Things I told him to try was to delete all the windows passwords (why they use windows passwords and networking passwords I'll never know) including those found in the win.ini file. I told him to try deleting all of his network protocols, ms networking, and all that jaz, then reboot and re-install them. I also told him to check permissions on the servers for these three users (he said it's been the last three in a row and probably the next person that had to do this would have it happen as well).

Any other suggestions you can think of?
