DNS WINS IE server not found

I am having a problem accessing one of my intranet servers in IE. It used to work but does not any longer.
I have a server named vTomato with shared folders on it. We direct our users to access it by opening IE and in the URL enter \\vTomato\  and the window opens displaying the available folders. That part works fine. The server IP is 10.1.11.6 .
The problem is that we also want then to access it by using the name \\Tomato\ as well, getting the same result.
In our local AD DNS servers I have (A) and (PTR) records for both vTomato and Tomato.
I can open a Command Window on any LAN station and Ping vTomato and Tomato and they both return a good response from 10.1.11.6.
When I open IE and put the URL \\vTomato\ in the  box and press enter the folders appear in a new Browser window just fine. But if I enter \\Tomato\  I get a error message that says:
ADDRESS BAR: Windows cannot find \\tomato\. Check the spelling and try again.

I tried deleting the (A) and (PTR) records in DNS for the tomato name and created a (C) record for it, but that did not work ether. The REAL servr is 10.1.11.6 and is named vTomato.

Can anyone point me in the right direction on this?

DNS Servers are Microsoft WIndows Servers 2003 Enterprise Ed. (x64)
Thanks,

Hi Dave,

Have you disabled Strict Name Checking on the vTomato server? It will reject connections on \\Tomato unless you do.

Linkage :)

The Server vTomato is a Windows 2008 R2 Standard Server.
The computers that are connecting to it are TERMINAL SERVERS (Client Sessions) running windows 2003 Server.

Do you think it would have the same problem?

Yes, when you do this it creates an SMB session:

\\ServerName

That's where Strict Name Checking leaps to the servers defense and why we potentially need it switched off here. The downside is that you have to reboot the server to find out whether or not it'll work.

And just in case, the StrictNameChecking issue / feature applies to all versions of Windows 2000 and up when accessing shares. But you'll only need change this setting on the vTomato server itself.

OK, I'll make the Registry change on vTomato (the 2008 R2 Server) where the share resides.
I cannot reboot the server right now though because it is a production server and in heavy use during normal work hours.
Right now the ALIAS server name (Tomato) is in DNS with an (A) record and a (PTR) record pointing to the REAL server's (vTomato)  IP 10.1.11.6. Is that OK or should I remove them and place a (C) record in there for (Tomato)? Obviously there are (A) and (PTR) records in DNS for the REAL server vTomato as well.

No, that's absolutely fine, no need to change anything there :)

It's considered to be an alias for the server simply because it's not it's real / bound name. It doesn't matter which record type you choose in DNS to get there.

OK. I've added the registry item and set it's value in vTomato. I'll reboo0t the server later tonight and see what happens then. I'll keep you posted.
Thanks,

Cool, hopefully this is all it needs. I'm confident, but there's always a chance :)
