http://support.microsoft.com/default.aspx?scid=kb;en-us;135464&Product=win2000

this is configured as second dc for backup, if I disable doest it function normally? will is see all computer in my network place?

help

Here is a pretty in-depth discussion of the Master Browser service and what it means.

https://www.experts-exchange.com/questions/20802862/Comprehensive-Master-Browser-Question.html

But the bottom line is that you only want one M Browser running on the network...  In a domain, it is always the DC.  If you have 2, then you can turn one of them off....

FE

I did stop browser service on second DC  but last week when my First DC went down and it didnot switch to my second DC and no one can browse active directory objects....till my first DC came back online.


So, I did start browser server again on second DC.


any help

Ah yes, you must have one running, but it should have switched over automatically...  hmmm.

Check out your DNS on your 2nd DC and make sure it is properly configured.    It could be the cause...  Here are some links that may help you, along with some pointers:

Proper Installation of AD and DNS (example)

http://www.microsoft.com/windows2000/techinfo/reskit/deploymentscenarios/scenarios/config_sea_rk_dc_01.asp


Most problems with AD are related to DNS in some way.

1. Go to your Primary DNS server and make sure that the _MSDCS entries are there for your AD domain, if not then at the domain controller run "IPCONFIG /FLUSHDNS" followed by "IPCONFIG /REGISTERDNS" this will put the AD entries back.
2. on your member server installation make sure you can resolve the name of your domain. Do this by running "NSLOOKUP %YOURDOMAINNAMEHERE%". If you get no error messages like "Non-existent domain" then your DNS is probably OK.

Does your DC have dual-NICs (dual-home server?),  it is another issue to look at because it compounds master browser problem.

cheers

Gnart,

My First DC have Dual-Nics but I did disable second nic and using only one.


Fatal_Exception,

I did run NSLOOKUP %YOURDOMAINNAMEHERE command works ok it resolve to first dc and gave me If you get no error messages like "Non-existent domain" message.

please help.....

i am getting 8021 and 8032 probably every one hour.

HELP..............

THe problem is your dual-nic.  I will post the reference shortly...

cheers

One more thing on my second DC i have RAS card install too..and also act as a RAS server.


Help...

I thought it was a dual-home that was causing the problem.... remove the NIC if you are not using it.... here is the reference...

http://support.microsoft.com/default.aspx?scid=kb;en-us;135404&Product=win2000

I had solved same problem that others had posted before...

cheers

Gnart,

I already disable second NIC on First DC and I start getting this error recently it was working good since last four years.

help,<<<

As Gnart mentions, the problem probably lies with the dual nic..  On my last server(s) installation. in fact last week, I actually had to pull out the second NIC on all three servers and reinstall.  Thankfully, they were virgin machines...:)  

Will look forward to Gnart's next post, as it will help me in the future... :)

FE

Gnart,

Thanks for reference link but I have Dula Nic on First DC not on second Dc. But I getting this error on second DC not on First DC.

any help

dma,

Go into the registry and lookup the object to see if _{7B9E8A74-AF3B-4EE7-. is a NIC or the protocol GID.  If it's a NIC see which one.  What's unusual is that it's coming from the server.  Have you introduced any XP or W2K3 into your network?  These have higher priorities even with the PRO versions, they will attempt to force election on the primary (W2K) server, once that's done; the primary server will then force the election on other DC....  Disable XP Pro master browsers....

cheers

This is my NIC card on my Second DC and everything look good.

Help

Yep, if the master browser stops working a secondary must be available to take over... Here is the article:

Your problem could be a problem network.  The problem may be UDP forwarding by router or switch:

http://support.microsoft.com/default.aspx?scid=kb;en-us;135464&Product=win2000

I think this problem is more like the UDP.  But you should check the master browser settings:
