I have installed SEM 11 MR3 on 23 servers with no problems. Last night I installed it on one of my 2003 SP2 Terminal Servers and things have not been good since.  Clients couldn't connect, local users couldn't connect to the file shares on that server, etc....    I tried uninstalling via Add/Remove and that bombed and only removed it from add/remove. Was still running on the machine. I found the SEM removal tool and used it.  The teefer2.sys junk was still stuck on my network adapters and I was/am unable to remove it.  Some of the adapters were simple and I was able to just delete them and let windows find them and install them, but teefer is still on my virtual adapters which I can't remove.  Any ideas?
