Can't Access File Share Through Secondary NIC on Server

I have a Windows Server 2008 R2 file server that is sharing out a folder.  The server has three NICs that I would like to use to share out the same files but each for a different purpose.  I can access the share with the server host name but I cannot access the same share through DNS names that are pointing to the two other NICs.  NSLOOKUP (forward and backward) proves that the IPs on the second and third NICs are correctly resolving to the host names but the share still doesn't come up through Explorer.  However, I can see the shares through the second and third NICs if I replace the DNS name with IP.  Why would I be able to resolve the IP correctly to a host name but can only browse the shares through IP and not host name?

I've seen this before.  It's got to do with the standard config of the Server Service only taking SMB/CIFS requests by ("real") server name or IP address.

Try this...

1) Start Regedit
2) Locate and click the following key in the registry:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
 
3) Add the following value

Value Name: DisableStrictNameChecking
Data Type: REG_DWORD
Value: 1


That's off the top of my head.  I know it works for Server 2003.  Should be the same for 2008.
