Master browser doesn't appear in its' own browse list

[Guest]

My network is as the following
All workstations and servers are on the same LAN, IP subnet and no routers involved. Also, I do not have WINS installed.
Some machines do have NWLink IPX installed but the machine I am concerned with is running only TCP

AD DC's are Win2k SP3
PDC Emulator is Win2k SP3. (AD01)
Client machines are a mixture of Windows 2000 servers and XP workstations.

When I run Browstat mb \device\network_tcpip it reports the correct master browser (AD01).
When I view a network trace from a workstation as it loads Network Neighbourhood, it looks to MSAD01 for its' network neighbourhood listing.

The issue is that the master browser doesn't appear on the neighbourhood, nor does it appear in browstat view \device\network_tcpip \\ad01 although all other machines do.

NetBIOS browsing over TCPIP is enabled on the WINS tab.
Restarting the server and forcing elections doesn't help. I have followed the instructions from MS KB 188305 and have tried using browcon though this reports an error (Domain Master Browser was not found).

Does anyone have any suggestions. Like I said, no WINS but all machines are on same subnet. I get the same results if I run any of these tools on AD01

TIA

Mark

Hi Mark,
Would it be possible to move the PDCe role to a different DC, to see if
the problem gets corrected? I've this occur for different reasons.
Sometimes it's Anti Virus or other Filter Driver causing the problem. I
would first just move the role and see if the problem clears up. If you
does and that is satisfactory you can run like that. If it does but that is
not satisfactory, you can move the role back, then I would suggest
disabling 3rd party services reboot the computer.

I see no reason to install WINS in this scenerio and it appears the
Computer Browser Service is working correctly. It would be interesting to
see if the AD01 starts getting listed in the Browse List once the Role is
Moved. Could be a Host Announcement issue on AD01.

Hope this Helps!

Why aren't your servers at SP4 yet? How about the clients? Do they at least
have the ms03-039 patch installed?
Does the ipconfig/all from the clients show that everything is pointing to
the server-IP? If you don't connect to a Novell-network, you don't need the
IPX-protocol.
How many nics in the server? Have you checked the bindingorder and made sure
the internal nic is on top?

First a reply to Alan,

Have changed the PDC role over to AD02 and they both now turn up in the browse list. Upon change back AD01, AD01 has remained in the browse list.

Marina,

I'm not running SP4 yet because we don't believe that at present we need the fixes it applies, in fact on the majority of our servers (Citrix) we will NOT be installing it because of the issues it causes, at present I believe there are 17 hotfixes for TS environments.

The RPC hotfix MS03-039 is applied and as previously mentioned we are able to map a drive to \\AD01, we are also able to remotely monitor and it is performing its' functions correctly so don't beliebr their to be an issue related to that.


Does appear as though the server wasn't announcing itself correctly, although whether this has fixed it i'm not 100% sure as would like to reboot the DC's to ensure that everything comes up as expected.

thanks

change that.

the server disappeared when i returned it to the pdc emulator role after a period if time. (sure I waited an hour or so)

Anyway, when AD02 is PDC emulator all servers appear in browse list
When AD01 is PDC Emulator, AD01 does not appear in browse list. Haven't tried disabling virus software etc yet but may if no other suggestions forthcoming, in the meantime any other ideas?


(all machines single NIC no teaming)
Citrix servers have IPX on as they connect to Netware servers, moving to IP only in future
AD DC's do NOT have IPX
Network neighbourhood from AD01 doesn't show itself, so only browsing on TCP.

TIA

That would be my suggestion.

Rule out any 3rd party software on AD01....
Is there a problem with just leaving AD02 as the PDCe?

Thank you,

I did post a reply this morning, but it doesn't appear to have arrived.

Servers are not running any third party tools (i.e. virus scanning)

Essentially whichever server is the PDCe disappears from the browse list. If I do a browstat view it doesn't report an MBR however browstat gm does.

Rebooting the server reports it going through the browser elections on network trace, however doesn't report itself as domain master browser. Registry values are set for isdomainmaster & maintainserverlist, although a W2K PDCe should ignore these anyway and just enforce them.

Have also installed WINS, no server reports itself as domain<1d> (netmon trace reports the broadcast stating this) Netmon also reports broadcast to __MSBROWSE__.

Any other ideas?

ps. Have upgraded both servers to SP4 to see if resolves but no joy.

 

[Alan Wood [MSFT]]

Please note that the Domain<1d> record is a broadcast record and should not
appear in the WINS DB. The only record related to Browsing in WINS is the
Domain<1b> DomainMaster Browser\PDC record. The reason is that segment
master browsers are just that Segment, so there is no reason for them to
register in WINS.

Thank you,

Any idea why browstat view doesn't report any server as a mbr, whereas browstat gm does?

browstat view also doesn't list the PDCe (hence why no MBR).
