Whenever I sync my device I get the following error:

"Windows - System Error
A duplicate name exists on the network"

Where do I go to delete the "duplicate name?" Only one device shows up under file/mobile device in activesync.

this link is interesting:

While that is interesting, and coincidentally my device name was the same as my workgroup name, changing the device name did not get rid of the error.
