[LAN] Multiple NICs to three subnets, DNS issues

[Vitalix]

Hey guys and gals,

We have a Win 2K3 server with 3 NICs installed. The subnets are 192.168.50.X, 70.X, and 40.X, all class C.

The reason we want those 3 to hit those subnets is that we have a gigabit connection to each of the subnets from the server. The name of the server is Atlas and it is in AD on the 50 subnet (registered in DNS). What I tried to do in DNS is add an entry for each subnet, for example, Atlas50, Atlas70, and Atlas40 for the the three subnets.

The problem is anytime I try to map a drive to any AtlasXX, it doesn't work! Says I got a duplicate name on the network! If I map to Atlas itself, it works, but then I run across the 50 subnet and lose gigabit and take extra hops through routers from the 40 and 70 subnets.

Is there any way I can setup Atlas so that it can be accessed from each of the subnets using separate DNS?

Thanks in advance as always!

EDIT: Changed thread title. Please follow the rules!

Are all three subnets within the same AD forest? If so, have you defined the three subnets within AD?

Actually I found the fix, it's not DNS at all! Rather Win2K and 2K3 are not set to 'listen' on the SMB for alternate DNS aliases other than their configured AD name. There is a registry entry that must be entered, and after that everything works great!

Just in case others may encounter this, the known issue is listed on Microsoft's site here.
