Ok. Got it working. Turns out the accounts have to be EXACTLY the same on both machines! On mine, even though the name was the same, the actual username was not! You can check this by going to compmgmt.msc, click "Users & Groups" on the left, then clicking your account. The first column says the account name, the second the name that you see when you login. Both have to be identical on both machines! Microsoft, you guys are a bunch of a-holes! Obviously none of you has EVER run a network!
