ok, this is what I'm thinking... Create an account on your local machine that mirrors the account on the remote machine. IE, same name and password. lets say they are admin
assword1
Then open a run dialog and type the following
runas /user:admin cmd.exe
press enter, and then at the prompt type: Password1 and press enter. That should allow you to run a cmd session as admin locally to your machine. THen type compmgmt.msc at the command line. This will open computer management as admin. Then try to connect to the remote machine as I described it above.
good luck
