SBS 2003 SP2 installed - Outlook does not connect

[Sergedt]

Hello,

I am in a real mess!

I have a SBS 2003 server (2 Nics). It worked perfectly until now.
I installed "Small Business Server 2003 SP2". Since than, none of the user's PC can have access with Outlook to Exchange Server, or to the local Intranet.
Internet works for every body. The connexion to the server (shared directories) works.
If I want to open Outlook, it is now "disconnected". If I want to access the intranet (which ran perfectly before), I get a message "unable to connect".

Every thing appears after the installation of SBS SP2.
I already applied the ISA server 2004 SP3 (I could hope), but still the problem.

The problem is that it is impossible to uninstall that SP2 (and come back)

Has anybody an idea? What has been changed (I am comparing with two other sites I manage, I do not see the difference)
Thank you already

I finally found the solution (you can find lots of suggestions), but the one who worked (for me) was the "936594 package" from Microsoft.
Every thing runs perfectly again (after one night of battle against the server).

Bye
