Slow Network Performance on SBS 2011

I can't believe we are having a re-run of two years ago, but if you have deployed SBS 2011, you need to run this hotfix if you are running antivirus software on your Small Business Server. Go to http://support.microsoft.com/kb/2493361/ to get it. For some reason unknown to me, the Windows Server Team felt that something released in Server 2008 SP2 wasn't important to put back into Server 2008 R2. I'm glad I have low blood pressure normally, because it just raised a few notches when I found this out.

When upgrading to WFBS and WFBSA 6.x from previous versions of Trend Micro WFBS and CSM for SMB, I've had multiple times where the Worry-Free Remote Manager Agent install fails and gives the following pop-up error:

Unable to load Library C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\{43F8CF32-15B7-44DD-A01D-A3372DD2856E}\zlib1.dll.

If you run across this, Trend has a great KB that will walk you through doing a manual removal. If you keep the GUID in your Worry Free Remote Management Console, then you can do a copy and paste into the new install of the agent and you'll be set.

If you don't feel like clicking through to the KB, here's a copy of it as of 9/8/2010:
