Password lockout every 30 minutes

I've got a win98 user who reset their password yesterday. He can log on to the network fine but after 30 minutes he gets prompted that he is denied access to our file server. If he keeps trying to get to it he gets locked out. When I unlock his password he can get back onto the network fine and to our file server fine. Then in about 30 minutes he gets kicked off of the file server and everything repeats. No one else in our company is having this problem. It seems that the pdc or bdc is checking his authentication every 30 minutes or so and this is causing the problem, but our PDC and BDC are suppose to be continuously synchronized. I even had the user change his password via User Manager directly from the PDC and he still gets kicked off after about 30 minutes. Is there any place win98 would hold an old password?

I would recommend deleting any .PWL files on the workstation and unmapping all network drives and disconnecting/unmapping any printer ports. Reeboot, then remap everything again.

Thanks Pat. I removed all of the .pwl files and disconnected all of the user's driver mappings. So far so good. It's been over 2 hours and he hasn't been locked out. Is this typical behavior of Win98 or the NT server?

Thanks

Sometimes when you map a drive, you are prompted for a password. It then CACHES the password in the PWL file. It also does this for printers and other network type connections. Windows NT Workstation does not CACHE passwords in the same way, especially if part of an NT Domain.
