I have a Server2003 server which started to have the error in the subject:
System error 52 has occured "You were not connected because a duplicate name exists on the network."
I get this error when I'm trying to access the server named "FileX" (server 2012) by it's A name record "store" such as "net view //store"
There is an A record on the DNS server "store" which points to the IP address of the FileX server (10.0.150.100).
This happens to be the only server 2003 server, so I can't replicate if this happens in all the servers or not.
"nbtstat -a store" returns "Host not fount" error.
net view //FileX does lists the files, no problems there.
I have tried the following:
Add NetBios name for the server: http://www.techrepublic.com/blog/the-enterprise-cloud/adding-multiple-netbios-names-for-windows-servers/ -> I made this on the FileX server, but did not reboot.
The suggestion provided by MS: http://support.microsoft.com/kb/914056 -> Tried it on the Server2003 machine, did not work.
I have tried editing the hosts file, disabling NetBIOS but haven't found a cure yet.
I'm not very familiar with netbios (too old for me) so I'm expecting some help.
