    Hi

    The following solution may help.

    SYMPTOMS
    ============
    A Windows 2000 domain controller may exhibit connectivity issues if the
    domain controller is configured in the following manner:
    - Routing and Remote Access Service (RRAS) is configured to permit incoming
    connections.
    - Domain Name System (DNS) is installed and configured locally.
    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 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:
    http://server_name/myconsole
    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

    CAUSE
    =======
    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.

    RESOLUTION
    ============
    WARNING: If you use Registry Editor incorrectly, you may cause serious
    problems that may require you to reinstall your operating system. Microsoft
    cannot guarantee that you can solve problems that result from using
    Registry Editor incorrectly. Use Registry Editor at your own risk.

    To resolve this problem, obtain the latest service pack for Windows 2000.
    For additional information, click the following article number to view the
    article in the Microsoft Knowledge Base:
    260910 How to Obtain the Latest Windows 2000 Service Pack

    NOTE: You must implement the registry changes that are described in this
    section before you install the service pack.

    To resolve this issue, disable NetBIOS for all RRAS connections (dial-in
    interfaces, server-side only). To do so, follow these steps:

    1. Edit the registry:
                     a. Start Registry Editor (Regedt32.exe).
                     b. Locate and click the following key in the registry:
                            
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters
                     c. On the Edit menu, click Add Value, and then add the
    following registry value:
                            Value name: PublishAddresses
                             Data type: REG_SZ
                             Value data: IP address of the internal interface.
    If more than one IP address needs to be specified, separate the addresses
    with spaces.
                      For additional information, click the article number
    below to view the article in the Microsoft Knowledge Base:
                      289735 - Routing and Remote Access IP Addresses Register
    in DNS
                    d. Locate and click the following key:
                           
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters
                    e. On the Edit menu, click Add Value, and then add the
    following registry value:
                            Value name: RegisterDnsARecords
                            Data type: REG_DWORD
                            Range: 0 through 1, default value: 1. Change this
    value to 0.

                            NOTE: The preceding key disables the registration
    of Netlogon A records for the domain name. After you set this value to 0
    (zero), you need to create two A records in DNS: one in the root of the
    domain for the domain name (for example, a blank host record in your
    company.local zone), and an A record for your Global Catalog (for example,
    your SBS server) in gc._msdcs.domain name.com. To do so, follow these
    steps:
                           - Click Start, point to Programs, point to
    Administrative Tools, and then click DNS.
                           - In the console tree, expand the Your Server branch
    (where Your Server is the name of your server), expand the Forward Lookup
    Zones branch, and then click Your Domain Name, where Your Domain Name is
    the name of your domain.
                           - On the Action menu, click New Host.
                           - In the IP address text box, type the internal IP
    address of your server.
                           - Leave the Name box empty, click Create Associated
    PTR Record, and then click Add Host.
                           - When you receive the "(same as parent folder) is
    not a valid host name. Are you sure you want to add this record?" message,
    click Yes.
                           - Under Forward Lookup Zones in the console tree,
    expand the Your Domain Name branch, expand the MSDCS branch, and then click
    the GC folder.
                           - On the Action menu, click New Host.
                          - In the Name box, type the name of your server as
    the DNS computer name for the new host.
                          - In the IP address box, type the internal IP address
    of your server.
                          - As an option, select the Create associated pointer
    (PTR) record check box to create an additional pointer record in a reverse
    zone for this host, based on the information that you entered in the Name
    box and the IP address box.
                           - Click Add Host to add the new host record to the
    zone.
                    f. Locate and click the following key:
                           
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\Parameters
    \IP
                   g. On the Edit menu, click Add Value, and then add the
    following registry value:
                            Value name: DisableNetbiosOverTcpip
                             Data type: REG_DWORD
                             Radix: Hexadecimal
                             Value data: 1 or 0. 1 = DisableNetbios.
                   h. Quit Registry Editor.

    2. Check registrations in the WINS database.
                  a. Go to Start/Programs/Administrative Tools/WINS.
                  b. Click on the plus sign to the left of the server's name to
    expand the list.
                  c. Right-click on Active Registrations and select Find by
    Owner.
                  d. In the This owner box, select your server's IP
    address/name (by default, would be the only on listed) and click the Find
    Now button.
                  e. Double-click on the entries for the servername[00h], and
    servername[20h] to verify that there is only 1 IP address on them.

       If the IP address for the dial-in interface is listed (or other IP
    addresses from the internal LAN subnet), delete these entries from the WINS
    database. To do so, follow these steps:
                 a. Right click on Active Registrations and select Delete
    Owner.
                 b. Select your server's name/IP address in the Delete this
    owner box.
                 c. Select the option to Delete from this server only (since by
    default it would be the only WINS server in your SBS network).

                 NOTE: RAS/VPN/Remote clients may not be able to connect to
    machines on the internal LAN since netBIOS names that were registered in
    WINS were removed and will be re-registered in the WINS database until they
    are either rebooted or their next refresh interval occurs.

    3. Obtain and apply the following fix:
                   To resolve this problem, obtain the latest service pack for
    Windows 2000. For additional information, click the following article
    number to view the article in the Microsoft Knowledge Base:
                    260910 - How to Obtain the Latest Windows 2000 Service Pack

                    The English version of this fix should have the following
    file attributes or later:
                     Date Time Version
    Size File name
                    
    ----------------------------------------------------------------------------
    ---------------
                  4/17/2001 7:23:40PM 5.0.2195.3516 197,392 Rasppp.dll
                                            
    4. Restart the computer to apply the changes.
