Just wanted to let you all know... Thanks for the comments and suggestions. It appears the user did a system restore (and didn't tell me), which is fine. She's a good enough user to do that. And now it's working well. It was the iMac having the problem (Dual G5) not the iBook. When she took the iMac to another office it worked fine. So we got her a new network cable. It worked for a day, then quit again. We thought it might be a wonky router port, but... Her laptop works just fine with it. I believe she's using IMAP, but can't remember for sure. But, at the moment, it's working fine. Thanks again for all of your comments and reference links and such. -dak ---------------------- Dak Aldrich Network Administrator College of Music, MSU 517-432-5045 [log in to unmask]
