Re: Microsoft Security Bulletin MS01-030

[Paul L Schmehl <pauls () utdallas edu>]

At UTD we are running active-active clustering (a-a-c) with two virtual 
Exchange 2000 servers and a RAID array.  We were in the process of 
installing Exchange 2000 on the second node, and the admins decided to 
apply this patch to the "active" node as well.

After application of the patch (this morning), stores.exe consumed 100% of 
CPU and Exchange became non-responsive.  Some tasks timed out, while others 
could be performed but were quite sluggish.

We do not know if this will affect systems that do not use a-a-c. 
Stores.exe is a file used by a-a-c, and the patch detected that we were 
running a-a-c.  There's nothing in the bulletin to indicate that the patch 
is not supposed to be applied to an a-a-c setup.
