Microsoft has been investigating an issue that affects all Windows Server 2008 products, but is shown up more so by things like Trend WFBS 5.1 and other antivirus software. The issue is that anything that uses the common firewall driver in 2008 will be affected. SBS2008 servers may start to have Active Directory errors, issues accessing the server via RDP and a variety of other errors. All this will start after 5 to 7 days. The only workaround so far has been to schedule a reboot of the affected server every 5 to 7 days.
It s important to note that the issue is NOT to do with TrendMicro products as it happens also with other AV vendors as well. It s a Microsoft issue and they have been working hard on resolving the issue. Microsoft have now released a hotfix for this which you can obtain from the URL below. The MS KB 961775 is not available just yet but should be out shortly.

UPDATE: if you go to the link above, it will auto detect the OS you are running and only offer you the patch for that OS. Make sure you select the Show all languages and platforms link so that you get the screen as below. And yes the Product is misidentified as Windows Vista that’s not a problem.

Good to know.
Might explain a few little quirks going around a few sites at the moment.
Dave Shackelford says
If you follow that link to KB 961775, you come to a page that provides a download for a Vista hotfix… Is it mislabeled, or is that the wrong link?
Ted says
Is there a x64 bit version of this hotfix? The link only shows a 32-bit fix. The install fails on an SBS 2008 server.
Brendan says
This hotfix is not mislabelled, Vista and Server 2008 versions are built from the same codebase, so you should be able to install the Vista version.
There is a x64 version of this patch, just click on the “Show all languages and platforms” link, and it will give it to you
Joel Kauffman says
This hotfix is included in Windows 2008 SP2.
This is included in Win2k8 sp2 so if you install SP2 you’ll get this needed fix
New AFD connections fail when software that uses TDI drivers is installed on a Windows Server 2008 or Windows Vista SP1 system that is running on a computer that has multiple processors:

John Lemonds says
I have this issue occurring even though I am at SP2 on the server. Yes, I do have Trend Installed. I removed the local AV client from the server but without any change. The hotfix labeled for Vista x64 will not install on SBS 2008.
