Add-On Congestion Control Provider
Add-On Congestion Control Provider is set to ctcp. To disable Add-On Congestion Control Provider, click Start, and in
the Search box type "command." in the results, right-click Command Prompt, and then click Run as administrator. At
the command prompt, run the following command:
netsh int tcp set global congestion=none

I don't think the last one applies to SBS but the other two should be acted upon...otherwise you can expect network issues.  Did the 3rd one come from the BPA?

I usually Click Start and in the Search box type:

runas /user:Local_Computer_Name\administrator cmd

to open a command window, the type:

netsh int tcp set global congestion=none

netsh interface tcp set global autotuninglevel=disabled

exit

I also don't usually bother with Chimney Offload, RSS, etc.
