Here is the error message I get.  

A duplicate name has been detected on the TCP network.  The IP address of the machine that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state.

When I do that nbtstat - n I don't see any conflict state.  Here is what I get

Local Area Connection:
Node IpAddress: [172.16.5.41] Scope Id: []

                NetBIOS Local Name Table

       Name               Type         Status
    ---------------------------------------------
    GCSERVER       <00>  UNIQUE      Registered
    GCSERVER       <20>  UNIQUE      Registered
    SAVAGE         <00>  GROUP       Registered
    SAVAGE         <1C>  GROUP       Registered
    SAVAGE         <1E>  GROUP       Registered
    GCSERVER       <03>  UNIQUE      Registered
    INet~Services  <1C>  GROUP       Registered

Check your computer name with names of other computers on your network. No two computers can have the same name on a network

That what I thought nbtstat - n was suppose to show if there was duplicate names.

Check the event log. Pull the IP from the data. Use NSLOOKUP to get the name. :)

This might be a duplicate wins name, check your wins server for all the names in the nbtstat - n output for different IP addresses
