This error apears when 2 computers with the same Computer name apears in the tcp/ip network. You should change Your computer name, or find another PC with the same name and change it's name.


Good luck!

Usually, yes, tgis error is recored when two computers, whether server or workstation, both have the same computername.   Usually, hostname matches netbios name.  Right click MY COMPUTER and select properties, then select the computername tab.  Note the name.   The first portion of the full computername, up to tge first period is almost always the netbios name.  The error suggests that you have two or more computers that have this part being the same.  Within a domain/netbios domain, hosts must be unique for full operations.

This error can also show up when a machine has recently changed it's IP address but didnt update the master browser, and or has multiple network cards or even if you've just swapped the network card.

How many computers that on your network? If not too many, simply go to each machine and verify it's name.   From the ctrl alt del login screen, select the Options button to dusplay the Log onto field--thisll show you name withhout having to logon.  If no computers have the same name, it was a false alarm.   If you do find that there are multiple machines with the same names, your users will be reporting odd behaviors and failures.
