I wonder if anyone can help with this problem on the work network. It occurs (usually) when a user tries to log on to a second workstation, but sometimes on any machine, the same thing occurs. We are running NT4 server, win95 workstation. The user logs on to the network and the script runs, but then the computer will hang with a disk page every 10 secs or so. CTRL-ALT-DEL, shows 'mprexe.exe not responding'. I think this is something to do with windows passwording? Tried deleting .pwl's, user profiles, user.dat....etc. Any ideas? Its a weird 'un. Jon

Thanks Traci, I've been experiencing problems w/ mprexe.exe as well. . . Microsoft notes that at least some of the time that these problems are caused by corrupted .pwl files, the files that are re-created after deleting and rebooting will also be corrupt. They give another program to run -- mspwlupd.exe. Unfortunately, I can't find it on the MS website. Any ideas?
