NT Server with 2 names

Hello experts,

recently I found an astonishing server where someone managed to assign the server two (!) NETBIOS names.

Net view \\name1 and net view \\name2 both reveal the same share list, and I can net use drives from the server with either name and always get the desired drive mappings. Convenient.

Technically spoken the server does own the NETBIOS names name1 <20> and name2 <20>.

Now I wonder how one managed to register name2 <20>.

Details:  no WINS, DNS, Hosts or LMHosts tables are involved. The server does have IP and IPX installed, but mainly IPX is used to communicate. I thought that probably the NET NAME command had been used, but could not find a way to make NET NAME register a name <20> entry (it does make <03> (Messenger) name registrations).

Who can tell me how the second name has been patched into the NETBIOS name table on that server?

This is called a NETBIOS name alias, and is basically how MS Cluster Server registers multiple NETBIOS Names.

To add an alias create the following reg key:

HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters\OptionalNames

Of type REG_MULTISZ

and put the alias names you require in there.  You need to stop/start the server service for this to take effect.

Life can be that easy ...

I found the key, and name2 is indeed present there. I guess you got it!

Glad to help.  I've used this when implementing new servers, it allows the new server to have an alias of the old server.

This means the clients can continue to connect to the original servername (giving you an easy backout route if things go wrong), and after you've migrated all the users to the new servername you can simply drop the old alias.
