Random crashes after installing 4.2.35 on Windows SBS 2008 64Bit

Last Sunday I installed the new 4.2 version on our server because after the update to the latest 3.x version the mirror update function wasn't working anymore (the complete service was gone!).

But after installed this, the Server completely crashed twice since sunday, no BSOD but a complet halt.

Any suggestions ? I now uninstalled 4.2 and wait for a couple of days to see if the random crashes are fixed.

Thanx

 

I removed this verion from the Server, no trouble anymore Since!

Nobody having the same problems ?/?

 

What did you have for exclusions? There are a LOT for SBS.
XMON/Exchange component running too?

 

Excluded

c:\inetpub
c:\program files\symantec\back exec\data\
c:\windows\system32\inetsrv\
d:\data\sq;\mssql.2\mssql\data\
d:\exact Globe\SQL\
d:\program files\microsoft\exchange server\mailbox\first storage group\
d:\program files\microsoft\exchange server\mailbox\second storage group\

Excluded web access protection.
No xmon running

 

I used this ms kb article as my basis for exclusions.

Although i don't install SBS only Server 2003/2008 the are also these for Exchange 2010 and Exchange 2007.
