After 3 hotfixes were installed last night no one can get to my MOSS 2007 site.
The hotfixes that were installed are:
KB2440591 (Vulnerability in Routing and Remote Access Could Allow Elevation of
Privilege)
KB2443685 (Daylight Savings Update)
KB890830 (Malicious Software Removal Tool)
I suspect that the problem is that the first patch modified reg key permissions
for the NETWORK SERVICE account, but I'm not sure. Any help?
