I'm getting this error on my 2008 win server:

Log Name:      System
Source:        NetBT
Date:          17/03/2011 8:37:17
Event ID:      4319
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      DC-01
A duplicate name has been detected on the TCP network.  The IP address of the computer that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state.

so I typed it in a command window:

C:\Users\Administrator>nbtstat -n

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

                NetBIOS Local Name Table

       Name               Type         Status
    DC-01          <00>  UNIQUE      Registered
    CVLO           <00>  GROUP       Registered
    CVLO           <1C>  GROUP       Registered
    DC-01          <20>  UNIQUE      Registered
    CVLO           <1B>  UNIQUE      Registered

Anybody that can explain what this means ?

Any help is greatly appreciated,

Kind regards,
