actually, which version of WHS you're using:
- there is "Windows Home Server" (WHS) that is based on Windows Server 2003 Service Pack 2. i'm not sure if that version has BDA (Broadcast Driver Architecture) support or not.
- also there is "Windows Home Server V2" aka "Microsoft Windows Home Server 2010" that i don't know if it's even released yet, but it's based on Windows 7 and Windows Server 2008 R2 technologies. so, even more unclear if it supports BDA or not, because as you may have heard Microsoft removed BDA support from their Windows Server 2008 products - there is a way to manually re-add it again:

however, as far as Microsoft OS has native or added somehow proper BDA support then TBS 6981 drivers will work.
