Windows Server 2003 Hotfix KB917537 installation failed

SBS 2003 on Dell Poweredge
Automatic updates are on (everything patched up to date)

Every night, for the last few nights I am getting:
Windows Server 2003 Hotfix KB917537 installation failed. KB917537 installation did not complete.

Following that, a bunch of other apps fail and the server finally reboots itself after 15 minutes (full details below).

Everything returns to normal following the reboot.  

The MS site notes problems with Proventia Desktop Agent & Bull Guard Suite v6, but I don't have either of these.

Any ideas? Should I disable this update?
Thanks
