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?
