I did sucessfully get WSUS off this server, but both before and after that success all other role demotions were the same result. sfc /scannow finds nothing windows update preparedness tool seems to accomplish nothing. machine is able to update .net 2.0 and 3.51 are on it and patched machine updated for all non optionals. I ran sfcfix and it found 40+ corruptions, but unsure where to go from there. attaching .zip file of CBS i'd really like to get this off the domain cleanly as possible. it s a decomm attempt.
