Network broswer 1

[fandabbydosey]

Hello,

My 2003 member server is having trouble finding the browser master on the network. The event log reports that there maybe a loss of network connectivity, but there has not.

Event Type: Warning
Event Source: BROWSER
Event Category: None
Event ID: 8021
Date: 24/03/2004
Time: 09:39:20
User: N/A
Computer: SERVER1
Description:
The browser service was unable to retrieve a list of servers from the browser master \\SERVER2 on the network \Device\NetBT_Tcpip_{AB1284EF-BCCB-4101-80EF-2FF9F45F89C2}.

Browser master: \\SERVER2
Network: \Device\NetBT_Tcpip_{AB1284EF-BCCB-4101-80EF-2FF9F45F89C2}

This event may be caused by a temporary loss of network connectivity. If this message appears again, verify that the server is still connected to the network. The return code is in the Data text box.


I posted a thread very similar recently, and was advised that it maybe because I had 3 network cards bridged, this may be the cause. I have un-bridged the network cards and only have one cable from the server into the switch. And only one of the network connections is enabled.

I have also noticed that browsing the network takes longer than expected, all DNS and IP configuration is setup correctly.

It got me baffled. Any advice anyone?

Thanks
Fandab

Here is a pure cut and paste from Technet.

WORKAROUND
To work around this problem, do one of the following:
Unbind all but one of the TCP/IP subnet transport bindings from the workstation service.

-or-
Remove all but one of the network cards or RAS connections.

-or-
At the command prompt type the following command:
net stop browser

Note This option prevents you from receiving computer browse lists from other networks.
After you perform these steps, wait at least 10 minutes to see if the errors still occur. If they do, continue troubleshooting by cross- referencing 2 pieces of information. First, check the transport that failed in the event log. For example, error 8021 displays a message similar to the following:
The browser was unable to retrieve a list of servers from the browser master \\<server_name> on the network \Device\NetBT_<driver_name>. The data is the error code.
The important data is NetBT_<driver_name>, which indicates the protocol and netcard binding, also known as an "endpoint." The potential protocols you may see are:
Nbf_netcard = NetBEUI
NetBT_netcard = TCP/IP (or NetBIOS over TCP/IP)
NwlnkIpx = IPX/SPX (NwLink) [will not indicate netcard]
NwlnkNB = NetBIOS over NwLink [will not indicate netcard]

After you have determined the failed protocol endpoint, check the working status of the Browser service on all installed protocols with the Windows NT resource kit program Browstat.exe. At a command prompt, type the following command:
browstat status

This will enumerate the browser status on all endpoints. Look for the message Browser is NOT active on domain under each endpoint. Disregard data about endpoints that list "NdisWanX" (such as Device\NetBT_NdisWan5); these are RAS endpoints and will usually list the error anyway.

You should find a protocol match between these two steps. The next step is to record any important information about the protocol from Protocol Setup in the Network tool in Control Panel. Then, remove the protocol, restart the computer, and see if the error no longer gets logged (remember to wait at least 10 minutes). Then, try reinstalling the protocol, checking for the error, and reapplying the service pack that exists on the current Windows NT installation.

If the error persists after a protocol reinstallation, you may have problems with the network adapter card. Check with the vendor to see if there is an updated driver, or try another network adapter card.
