After I installed my networking software on my dell I had to change the name of the device. When I was finshed with the install I changed the device name back and now I get the message that " A device with that same name already exists". Can someone tell me where I can delete the device. If I don't hit "ok" nothing syncs up.

On the PC open ActiveSync. On the File menu there is an option to Delete Partnership. Simply delete the old partnership and re-create the new one.
