Allowing NetBIOS responses on a DNS Alias in Win 2K3

You must disable "Strict Name Checking" on Windows 2003 server to allow the server to respond to a DNS alias. This is done via registry editing:

HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters
Value name: DisableStrictNameChecking
Data type: REG_DWORD
Radix: Decimal
Value: 1

This allows the Server "Server1" or "Server1.MyDomain.Pri" to respond to a DNS entry like "CoolService" or "CoolService.MyDomain.Pri"... This is disabled by default, as it loosens security. It is not recommended to do this in a DMZ or Internet Zone.

FYI, a reboot is required to make the change work.

I'm a long time computer nerd, living and loving technology wherever I can find it. I've recently shifted from a focus in MS SQL server, MSCS Clustering, and High Availability Engineering to focus on collaboration technologies, including SharePoint 2007. I recently moved from my long-time home in Seattle Washington to Salt Lake City.
