Internal clients can't access the Internet after a remote client connects to RRAS
Symptoms: After a remote client establishes a connection on a RRAS which is installed on a domain controller with DNS, one or more of the following symptoms may occur:
1) Internal clients may no longer be able to browse the Web through Internet Security and Acceleration (ISA) Server, regardless of whether or not Web Proxy or the Firewall Client is being used for Web browsing.
2) A "The page cannot be displayed" error message is generated when you use a Web browser.
3) A "cannot find server or DNS" error occurs.
4) From an internal client, if you use PING to ping the name of the server, PING returns any other address other than the IP address that is bound to the server's internal adapter.
5) You cannot browse through the list of computers in Network Neighborhood or My Network Places.
6) You cannot connect to the following Web page: 7) You may receive the following event message: 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.
8) When a client clicks Update Now from the Firewall Client applet in Control Panel, the client may receive the following error message:
The server is not responding when client requests an update.
Possible causes:
-The server is not an ISA Server.
-The server is down.
9) Windows 2000 LAN 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: This issue can occur if the client computer receives a response from DNS that includes the wrong Internet Protocol (IP) address. This address is only returned in a query after a remote client has connected by using Dial-Up Networking. This IP address is registered with DNS if network basic input/output system (NetBIOS) is bound to the RRAS server's dial-in interfaces or if DNS is configured to listen on all interfaces. To resolve this problem, obtain the latest service pack for Windows 2000. Or refer to MS Q292822.
