I have an Exchange Server 5.5 Sp3,70 users, 768mb RAM, RAID 5 76gig. It has been stable for the past 3 months. Just the other day all my Outlook clients could not send mail and hung on opening their mailboxes. No immediate error msg or event erroron the clients or server. All Oulook 2000 clients hung indefinetely. After a failed attempt to restart my Exchange Serices I rebooted the server. After reboot all is well again.

Anyone else experience this that can offer advise?

Ive experienced a similiar problem with Outlook clients trying to access Exchange Server. Exchange primarily uses Net Bios name resolution. If you dont have a WINS Server or use host files the clients are constantly broadcasting to locate the Exchange Server. This creates a large amount of traffic and bottlenecks your server when multiple clients are accessing it. Try either WINS or Host files.

No this is not the issue. I run both WINS and and local host files on all my clients. Matter of fact after the last incident which was 10/25/00 it's been stable again, but this morning the same thing happened again.

No event loggings or error msgs. Server was running fine last night. No outlook clients are able to connect and I cannot stop/restart any Exchange services. Another reboot is required!!! Shit!

Help!!!

I have had the smae problem, but it had nothing to do with the exchange server. It was a network failure (burp) which hung RPC communications on the Exchange server. Boy was it a bear to figure out. But I need more info on this one... anything in your error logs?
