Domains/Workstation Item listed in Network Neighborhood

How does one go about purging the Master Browse list or otherwise removing above mentioned items that are no longer on the network and should not be listed in Network Neighborhood?  As I understand, the listings should refresh themselves and after a period of time, no longer reside on the list as it is no longer broadcasting NETBios packets.  Any way to manually remove them?

if your only protocol is tcpip, just try disable netbios over tcpip, or just disable workstation service at all. hope it helps, bbao

Hmm  You are correct.  The master browser SHOULD refresh itself and clean up entries that do not reside on the network.  Are you in a Domain or Workgroup?  Do you know which machine is the Master Browser?

We're in an Active Directory environment, and our master browser should be our DC that is also the operations master.

Never had to manually remove these items.  I would follow bbao's advice if you are not using netbios, which you should not need in a W2K domain anyway.   And you are right, in a W2K domain environment, your DC is your Master Browser.

Maybe you can throw together a batch file to run on your domain controller that runs the Net Computer command to delete old computers from the domain.

If this is a workgroup-only scenario, you'd have to find out which computer is the master browser and run the batch file there.

I don't know if it would work, but it's an idea.

"nbtstat -R" purges and reloads the remote cache name table. The NetBIOS name cache contains every NetBIOS name that was recently associated with an IP address. You shouldn't be have having too many domains come and go...

If you're referring to XP's My Network Places, anything you accessed will be cached there until you remove it.

chicagoan, are you sure "nbstat -R" will stop netbios to provide further name resolving... ?? personally, i dont think so, but not tested it before.

chicagoan, sorry for confusion. i was just wondering about how to uderstand "You shouldn't be have having too many domains come and go..." you mentioned, hmm..., i did think what you meant was: by using "nbstat -R", you cannot resolve netbios name again so computer name list will not be available...

you know, english is not my native language... ;-))

Your english is better than a lot of the americans i know :)

I meant that domains are relatively permanent, that you don't see them changing much. Usually when a domain disappears, it is a problem.

nbstat -R just clears out the cache, similar to ipconfig /flushdns

Once resolved again, entries stay in the cache until the 'life' time expires.

i see, agreed, thanks for your comment.

btw, just found, a lot of askers do not reply experts comments on time, lead experts have a lot of assumptions and discuss with each others but no result eventually... haha... ;-D it seems the experts here care questions much than the askers... ;-))

i had already ran the command nbstat -R...one of our techs had created a test domain and the NETBios of that name remained even after the server was taken down.

Do you have WINS servers running?
What OS are you using?
If you're in an SD environment, why aren't you using pure tcp/ip and dns?

I agree chicago, i hardly even see Wins servers anymore.  They have their place, but if you don't need them why install them.

Although I do wonder why the master browser list is not purging itself as it should.    hmmm

I think we are back to turning off Netbios over TCP/IP.  This would seen like the logical thing to do.  That is unless you have legacy resources on the domain.

we do have legacy devices on the domain, and turning NETBios off would not be an option.

What does browstat getpdc show is the master browser?

Are you logging into the domain?

Are your legacy devices registered in DNS?

Are you using the DC as your primary DNS server?
