Can't resolve machine name, only IP

[q123we]

Hello,

It's been a long time since I learned Win2k Server & have a quick question. Can someone please WALK ME THROUGH what I need to do so that the local internal IP of 192.168.2.3 is resolvable by name instead of just IP address. I try to ping the machine by name and it doesn't come up. Once I use the IP address, it works fine. I'm sure this is a rudimentary question for some, but I'm stuck. All help is appreciated. Thanks in advance

Actually, not rudimentary, but we do need more info. Do you run dhcp, dns, wins, etc. Basic info like that. Glen A. Johnson

Yes, I run DHCP, WINS, & DNS locally. I'm not sure what else you're looking for.. (sorry)

Has this just started or has it never worked? How many machines are affected by it? Thanks. Glen A. Johnson

Hi q123we,

Have you configure a forward lookup zone on your DNS server?

Are all your clients pointed at the correct IP address for your DNS server in there adapter's TCP/IP properties?

Is there a host record in your DNS servers console that corresponds to the computer in question?

Hmmmm....

Glen -
This is a problem that just started.

Yes, I have the two ISP-supplied DNS servers in the forward lookup zone.

Yes, all clients are pointed to the internal DNS server in the TCP/IP properties.

Yes, there is a host record in the DNS console that cooresponds to the computer's name and IP.

After reading your questions, I think I've left out some crucial information. I'll provide some background info:

I have 2 networks, one for local users and shares, & one to host a webpage. The local users domain (I'll call it A) is seperate from the domain for the webspace (B) with no permissions between domains. Domain B doesn't use AD & is not part of a forest. After reading some other posts, I think I might have screwed up from the start by making domain B the same name as the URL (i.e.: mycompany.com)

When I originally set up domain B, it was on the same subnet as domain A - using DHCP through domain A's DC.

Both domains are behind a firewall. Domain B is using the DMZ port. I had to configure the DMZ port to be a gateway and used a different subnetted IP address. I then changed the webserver's IP to be on the same subnet.

After that is when problems started to arise. Since then, I've not been able to use the server name to terminal service into the webserver, I have to use the IP address to connect. I'm not able to ping the machine by name anymore, only IP. I can't see the webserver through network neighborhood. When I go to the browser and put in the website URL, the page cannot be displayed. I know I've made a mess of things...

You might have it. Can you change it back to the way it was and see what happens? Subnetting will get you everytime. (Had a similar problem trying to set up wireless network with cable modem. Modem using dhcp and was on a different subnet.) Let us know. Glen A. Johnson

Glen-

I checked with the firewall manufacturer's tech. support people, they said that the DMZ port has to be on a different subnet for security reasons. Since the webserver HAS to be on the DMZ port, I'm not sure that I'll be able to just switch it back to the old subnet just to get things running again. I guess I could temporarily change it back just to make sure that the problem is identified, but then I'm stuck again. In essence, I'm stuck with a new question: "How do I get my DNS configured to work with two subnets?"

"How do I get my DNS configured to work with two subnets?" As far as I know, you don't. I'm sure theres folks out there that know more about this than I, so I could be wrong. Anybody? Glen A. Johnson
