Vista SP1 with Antivirus Installed on Multiple CPU Systems Eats All Resources

Tip: Click here to update all your PC's outdated driversMicrosoft has warned customers of a problem affecting both Windows Vista Service Pack 1 and Windows Server 2008 RTM/SP1, where the two operating systems in combination with some antivirus software, and running on machines with multiple processors, can eat all the system resources available to them.
In such scenarios, customers with affected computers will run out of resources. The Redmond company explained that the problem was related to how third-party software, but especially antivirus products, uses Transport Driver Interface (TDI) drivers. In case the software solutions leverage TDI while installed on Vista SP1 or Windows Server 2008 running on computers with multiple CPUs, users will observe that the handle count of the system process increases continuously.
“There is a potential problem on Windows Server 2008 and Windows Vista SP1 multi-CPU systems that have software installed that use Transport Driver Interface (TDI) drivers. Anti-virus software is an example of such software. Many newer anti-virus software versions take advantage of our Windows Filtering Platform (WFP), new for Windows Vista and Windows Server 2008, but some may still rely on TDI. Software that uses WFP will not hit this resource depletion issue,” revealed Mike Platts, support escalation engineer at Microsoft.
The software giant explained that the problems affected only the first service pack for Vista and Windows Server 2008, and published KB961775 to help customers deal with eventual issues. A specific update is not available; however, a hotfix is in place, but needs to be accessed directly from the company. Still, affected customers can also download and install Windows Vista SP2 or Windows Server 2008 SP2, as Microsoft has resolved the glitch in the latest service pack for the two operating systems.
The company indicated that in case all system resources are depleted, users will notice that all new Ancillary Function Driver for WinSock (AFD) connections will fail. Still, there are additional symptoms described in the KB article:
“User authentication fails
Sysvol replication fails
One of the following Netlogon events occurs:
Netlogon event 5775
Netlogon event 5792
Netlogon event 5792
Netlogon event 5719
For example, the following is a sample event when Netlogon event 5775 occurs:

when it's a bug, i agree, but now it's the antivirus and not the os, please take that
into account when you create a title, this one seems like is vista's fault, and it's
not.
agreed! there's still a lot of vista bashing going on for no reason.
i have
never had an issue with vista after installing sp1 or sp2 and i'm always editing system
items and registry codes. i think the problem with vista comes with the majority of
users....stupidity or lack of understanding of how something works.
vista is still worse than xp or 7 it does not even compare to those two and to backup my
statement i remember when microsoft themselves slagged down their own operating systems
come on if the makers do not like it what does that say.
and before you say anything about stupidity or lack of understanding to how to use it i
code using mac and linux and sometimes windows my main system is windows 7 and i also have
systems alot harder to use than windows.
