Run "winmsd" and go to Components/Network/Protocol. Look at the
names in the list, anything with "MSAFD" in it or the "RSVP xxx Service

owning program might help.
If that fails or your provider list is empty, you may need to rebuild the
catalog from scratch. The following instructions will rebuild your catalog
for TCP/IP. If you are using any other transports (If you don't know, then
you probably aren't) then you will have to reinstall them as well.
