don't know if you'll see this post since the thread is like 6 months old, but
here goes... I have a compaq pc that came with windows media center so I had
to go thru this to get IIS to run...

check your services for Distributed Transaction Coordinator and start it if
its there. If not, install it by following this KB:

http://support.microsoft.com/default...b;EN-US;891801

then in command prompt navigate to %windir%\system32\inetsrv folder, and do
this:
1) rundll32 wamreg.dll, CreateIISPackage
2) regsvr32 asptxn.dll
3) IISRESET

hope it helps
