We have received some reports of a potential issue with MS06-025. Here is a snippet of what appears to be the problem as it was report to us:
"We received couple of calls that users are
not able to dial up after applying MS06-025 (KB911280).
I verified this on a test machine and it looks like it breaks dial up.
We have some scripts that need to be run in order to authenticate the user
properly after the dial up connection is established.
It looks like the patch prevents scripts from running at all. Even when I
turned on the terminal window (in interactive logon and scripting) I can't
log in manually at all. After the connection is established I can see the
Username prompt in the terminal window but I can't enter any data.
Uninstalling the patch fixes this."
Microsoft has confirmed they are getting some reports of this and have established a case number. If you are having similar problems, call Microsoft for free support, 1-(866) PC-SAFETY, and reference case number SOX060615700008.
