I used the command
netdom computername /add:newname.domainname.com to add a second name to a server running Windows 2008 Server R2. After restarting the server, I had DNS "A" entries for both names. In addition, the second name was added to
HKLM\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters\OptionalNames, which I believe should have taken care of any NetBIOS resolution.
From my Windows 7 workstation, I can
ping both names and running
net view on both names reveals the same list of resources. From Windows XP, I can
ping both names, but
net view only works on the first name. Running
net view on the second name returns:
System error 52 has occurred. You were not connected because a duplicate name exists on the network. Go to System in Control Panel to change the computer name and try again.
What do I need to do to make the second name usable from XP clients?
Update: I was able to resolve the problem by adding the REG_DWORD key
DisableStrictNameChecking = 1 to
HKLM\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters, then restarting the Server service. However, I do not understand why this was necessary.
