 Computer Name Changes Error
DNS errors
I have a problem trying to connect to a domain controller. When i try to connect from an xp pro. desktop to a windows 2003 server i get a response back "A domain controller for the domain XXXXXXXX could not be contacted. I looked in the details of the error and it tells me that the "DNS name does not exist". I logged into the server and tested the DNS and it passed. I can ping the server. I also did a dnslookup and it responded on the server dns. I than did the nslookup on the client but it redirects me to ISP DNS?? I have my desktop configured with a static ip address. I hope you can get a picture now. Please help!!! thanks..

1. I am attempting to join the domain. 2. There is no DHCP running. All are configured with static ip address. 3. I configured the desktop with the ip addresses that was assigned. i also configured dns and gateways on the desktop. However when i do a nslookup on the destop i get the default server of the ISP provider. This is the confussing part and probably the reason i cant connect to the server. How would i take care of this problem? I CANNOT ping from the server to the desktop. I CAN ping from the desktop to the server. are you attempting to join the domain or just connect? is the server set up for dhcp? are you connected to the same local network? if so, can you ping the client machine from the server? download ethereal. it is a free network analyzer. install it on both the server and client to view traffic in/out. randy

1. I am trying to join the domain.
2. The server is NOT setup for DHCP. Previous administrator has all STATIC addressing.
3. I am using the same local addressing scheme and default gateway, dns, etc.
4. I CANNOT ping from the server to desktop.

If you cannot ping the server, need to check physical connections first. Then go to command prompt and execute “ipconfig /all” and verify all IP settings: addr, subnet mask, default gateway,etc. Then try pinging 127.0.0.1 to check protocol stack, then try your own IP, then default gateway.

I checked the physical connection and i’m running the ethernet line to the same VLAN switch i’m trying to connect the domain to. I ping the server and got a response. However, i ping from the server to desktop its not replying. All IP address,subnet mask, default gateway, etc are the same. I ping the 127.0.0.1 and it replied.. and i ping my own default gateway on the desktop and it replied too..

Do you have the firewall enabled on the client pc? You will want to turn that off since by default it will block ICMP packets sent to it.

Are you utilizing multiple VLAN’s? Is it possible that the administrator prior to you setup a separate VLAN on the port you are using on the switch. Is this a managed switch? If so go into the config and see how the ports are configured and make sure that the settings match the settings of your nic and also make sure a separate VLAN is not configured for that port you are using. Are you certain that the DNS settings for the client nic are pointing to your DNS server? Make sure they don’t have the same DNS as the DNS server which might be pointing to your ISP’s Name server.

As SPDTech said:

Make sure that your preferred DNS server on the Windows XP PC is pointed to the domain controller. That worked for us.
