OK, the beer didn't help. Well, it helped but it didn't really help. I was able to get the connector to install without too much trouble last night. After I unplugged the wired connection, I let the computer stay on over night (on a wireless connection) and it didn't create a backup.
Something that I just noticed: in the Network and Sharing Center, it says that I am connected to my new wireless SSID (Undercover Police Van #9). BUT! The desktop shows that it is connected to the old network name (Undercover Police Van #4). I feel that part of this might be some of the problem. For instance, while on a wired connection, I was able to RDP into the desktop. After trying this over wireless, I got the same errors that I had been getting earlier.
Interestingly, I cannot connect to the server using the connector software (on wired or wireless connection). I'm grasping at straws at this point.
Undercover Police Van??? I hope you really are a cop, or you might just get a knock on your door
re: the wireless connection. Did you remove/delete all the existing wireless profiles before joining up to the new one?
