This from a 10.0 install:
c:\inetpub\logs\logfiles has an additional folder calle W3SVC1 with a bunch of .log files in it
c:\inetpub\logs\wmsvc is empty.
I wonder if you clobbered something else; I can't imagine that deleting some log files is enough to wipe out your services.
Why don't you simply try to publish the service(s) and see what happens.
That should just about do it....
