@Rob,

Thanks so much for that additional information. Glad that there are other methods to do this.

Another way to fix this, rather than stopping/disabling the Computer Browser Service is to unbind NetBIOS from Tcp on each of the interfaces. To find out which interfaces are bound, type 'BROWSTAT.EXE DN' at a command prompt - this will list the interfaces such as 'DeviceNetBT_Tcpip_{7B935...' as displayed in your System Event Log. Steps to disable NetBIOS over TCP:
1) Open Network Connections in the Control Panel
2) Open the Properties dialog for any interface
3) If TCP/IP is checked, select it and click 'Properties'. (If it is not checked, click 'Cancel' - this interface does not have tcp/ip bound)
4) Click the 'Advanced' button
5) On the 'WINS' tab, select the radio button for 'Disable NetBIOS over TCP/IP'
6) Click OK, OK, then Close

If you run BROWSTAT.EXE DN again, the list of interfaces should be one less now. Keep doing this for each interface in the list and you will eliminate all of these MRxSMB messages.

This can also be disabled using DHCP options if you are using DHCP on your network. Just be careful when you have legacy and non-Windoze boxes that need WINS to connect to the network.

@Jad,

I would say that you probably shouldn't disable on your SBS because that is part of what it is designed to do. I could be wrong though.

Hello Richie,
I am still having the same problem, i disabled the computer browser service on the client machine, actually on all client machines since the error is coming each time from a different one. Did you also disable it on the SBS?

Thank you

GENIUS! Thanks so much for solving this for me! I have been searching for ages trying to solver the master browser issue, that was periodically disabling my web server.

I have now found the machine running the Computer Browser service (why?!) and disabled it on SBS 2003. Now my web server is back up and running.

CHEERS!

@Jeb,

Interesting. Unfortunately I can't help you there as I'm not a Linux wizard.

What happens if the culprit is a Network Accces Server with Linux ( and no access to its services / registry)
