Name Resolution and Connectivity Issues on W2K Domain Controller with RRAS and DNS Installed
Symptoms: You may experience some name resolution and connectivity issues if the W2K domain controller is configured with RRAS and DNS. After a remote client establishes a connection by using Dial-Up Networking, one or more of the following symptoms may occur: 1. Internal clients may no longer be able to browse the Web.
2. A "cannot find server or DNS" error occurs when using nslookup.
3. When using PING to ping the name of the server on an Internal client, it returns any other address other than the IP address that is bound to the server's internal adapter.
4. You cannot browse through the list of computers in Network Neighborhood or My Network Places.
5. You may receive Event ID: 4319, Source: Netbt. Description: A duplicate name has been detected on the tcp network. The IP address of the machine that sent the message is in the data. Use NBTSTAT with a switch of N in a command window to see which name is in a conflict state.
6. W2K/XP clients cannot map a network drive to the server. The client may receive the following error message: No Logon Servers Available to Service your Logon Request.
Resolutions: 1. Install the latest service pack.
2. Make sure the clients have correct DNS and WINS settings.
3. Disable NetBIOS for all RRAS connections.
4. Double-click on the entries for the servername[00h], and servername[20h] to verify that there is only 1 IP address on them.
