Windows 2008 Clusters Only Accessible by IP

[blashmet]

We have 6 server clusters running Windows 2008. We can ping them via name and get a response. However, when we try to access them in Windows Explorer by name they can't be found. We can only access them in Explorer by their IP address. For example, we can browse to \\123.45.6.789\c$ but not \\servername\c$.

Does anyone know how to fix this?

Thanks!

bump...any additional info needed?

From a client, type the followings commands:

ipconfig /flushdns
nslookup
set querytype=all
SERVERNAME
exit
ipconfig /displaydns

post results

When I run ipconfig /displaydns it shows 3 different servers and their IP addresses. I can't post all of the output, but what info in there would help resolve the problem?

The combination of server1, server2, server3 with IPs are correct?

 

[blashmet]

Well, we can access them all by their IP so I assume so. I'm just not sure why we can't access them by name.

That's the point. With NSLOOKUP you can understand HOW one name is resolved into IP.

Do the steps above and check that each name is resolved correctly.
