2003 server, disappear master browser when client connect to RRAS

I have a win 2003 server as domain controller,with dns and wins server .
Clients are w9x, NT4, xp.
Also RRAS is enabled to allow esternal user to connect with modem.

When an eternal client connect via rras, from then internal network all
computers disappear from then network browser.
Netbios browsing consolle is not able to find the master browser. If I
restart RRAS the problem is solved.

I've notice then in dns and wins there is the ip address of the RRAS card.
I've read many article about this problem under W2k, does 2003 soffer the
same problem?
How can I solve?

With NSLOOKUP, if I resolve the server, I get two address, the nic and rras
ip first time, then rras and nic the second time and so on .

Thank you
Alessandro

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.

The problem is that, when a remote user connects, the server acquires
another interface with its own IP. As Robert pointed out, this is bad news
for both DNS and the browser service.

To prevent the browser problem you need to disable Netbios over TCP/IP
on the RRAS interface. This requires editing the registry.

To prevent Netbt on the RRAS interface.

Open Registry Editor.
Navigate to HKLM\System\CurrentControlSet\Services (continued next line)
\RemoteAccess\Parameters\Ip

Create a new REG_DWORD called DisableNetbiosOverTcpip
Set its value to 1

You will need to restart RRAS.

If you are using dynamic DNS, you may get a similar problem in DNS,
caused by getting multiple IPs for the server. You can usually cure this by
setting DNS to listen only on the LAN interface.

If I'll disable netbios, are NT4 RRAS client able to map a network drive?
Thank you.

Yes, The Netbios name still attaches to the machine, but only to the LAN
IP.
