Back in the SBS 2008 days we had many people that had slow network performance problems and it was finally narrowed down to a Microsoft TDI driver. The fix was easy – install either it or Windows Server 2008 SP2 onto the server and reboot and the problem was gone. The problem mainly manifested itself if you have AV from Symantec, Trend or Kaspersky or Microsoft’s own SCOM installed on the server, but was in fact due to the TDI.SYS issue and not products from those vendors. Naturally those vendors named got their fair of flack from all round as being the cause of the problem when in fact it was Microsoft that was the one with the issue.
Well guess what…With the release of SBS 2011, we get to relive that feeling of deja vu all over again… yup – you guessed it – this fix is NOT part of SBS 2011… FAIL for Microsoft on that part for sure. I would LOVE to know the logic behind Microsoft NOT including this fix in SBS 2011 given it was widely known to them and the community… it is unacceptable that we have to patch a brand new box to fix a problem that has been around for 2 years. To fix it you need to download and install THIS hotfix from Microsoft.
