Novell ZENworks 7 Desktop Management Support Pack 1 - ZDM7 SP1 Middle Tier
Microsoft Windows Server 2003 Standard Edition
The middle-tier service stops due to heap corruption.
Running IISRESET will temporarily restore the service.
Fixed in xzenwin32.dll dated 26 January 2007 or newer in HP3.
Customer originally opened a ticket with Microsoft which examined some dump files from the server.
These files seem to indicate that the corruption is cause by either xzenwin32.dll or ncplw32.dll
