SYMPTOMS
When a client computer connects to a Microsoft Windows 2000-based computer or a Microsoft Windows Server 2003-based computer by using an alias name, the client may receive the following error message:

System error 52 has occurred.

A duplicate name exists on the network.



CAUSE
This problem can occur when you try to connect to the server by using a CNAME alias that is created in the DNS zone. For example, this problem may occur with a command similar to the following sample command

'''net view \\. .com'''

where  is a CNAME record that is created for the server in the  .com zone. The server is not &quot;listening&quot; on the alias, and therefore is not accepting connections to that name.
