Multiple Server Names

Winzero ServerMigrator has an option to add multiple server names to one server. This feature is handy when trying to remap user connections by allowing the new server to have two names: the old server name and the new server name.

However in our customer's enviroment a server would not respond to a cname that had just been created. After using the multi name utility and adding the new name to DNS and then connecting to “\\SecondServerName\c$” the server responded with an error “A duplicate name exists on the network.” Windows Server 2000 and 2003 listens for it’s “netbios” name only and ignore requests that come through with any other name.

A Simple Registry Fix.


Check for or add the following registry value:

Value name: DisableStrictNameChecking
Data type: REG_DWORD
Radix: Decimal
Value: 1

Rebooot the server.
