Shares only show when connecting by IP

[Tekmazter]

First a quick overview:

1 domain, two offices Boston, MA and Dallas, TX. A domain controller in each.

Here's the problem. I can successfully connect from multiple computers in the Boston office to the server in TX by \\computername (UNC), but I cannot see any shares. However, when I perform the same action using the IP Address, I see them listed. This one has me a little baffled. I have dns records for this server and they have been replicated successfully to the TX server. All appears normal, but obviously it's not. I've checked replication of the domain controllers using Repmon and that has been happening successfully as well. DNS is the only thing hosted on the server in TX besides it being a domain controller. Would I be wrong in making an assumption that this is a WINS issue? I do have WINS hosted in Boston, but not in TX as I don't have any legacy Win9x clients there.

One other note: When I connect via the MMC to the DNS management console, I have to use the IP Address as well as when I try by Computer name it fails.

Oh, almost forgot ....and all users in the TX office CAN SEE the shares when connecting by name.

It looks like this is hardware issue and not something to do with my servers. I have isolated this problem down to a switch which as about 24 users on it. Moving those connection s to a different switch appears to have alleviated this issue.

Although I am not sure what if anything on this switch would cause this. It's a CISCO 2950. I have 3 of them all of which were configured pretty much identical.

Tekmazter,

Looks more like a DNS WINS issue but you better copy the "sh conf"s to text files and check out the configuration of you network equipment.
My money is on a Microsoft DNS or WINS error though. Also you should have a WINS server on both sites for all your windows stuff.
