Configuring Master Browser in peer to peer network

[Jill]

I have a five computer peer to peer network. I am constantly getting Master

Browser errors in the logs of all of the computers (MRxSmb Event ID: 8003,

BROWSER Event ID: 8021)



I realize these errors are not critical, but it bugs me that things are not

configured 100%. Also, the errors grab my attention in the log and distract

me form possibly seeing more serious errors.



I understand the concept of MB and how the election works in regard to OS

etc (all computers are XP SP3)



I have tried setting:

HKLM\SYSTEM\CurrentControlSet\Services \Browser\Parameters



'IsDomainMaster' to TRUE on one machine and FALSE on others

'MaintainServerList' to TRUE on one machine AUTO on others



What is the proper way to configure the MB in this network (there is no real

'server' or machine that is on all the time to maintain this list)?





Thanks guys

Hi. Thank you for your post.



This article talks about the registry settings I think I tried.

Maybe I am not configuring them correctly?

There is also a section talking about LSA. My computers are set to 0. Should

I play with these?

Jill,



Yes you are right. The errors are not that critical and I wouldn't worry

about them. These errors are also evident when somebody connects to a

domain using their own laptop and expects to receive IP address dynamically.



I wouldn't worry about these errors.

What I am wondering is if there is a better way to configure this though

I don't think so because an alien system won't be recognized by the

domain (I appreciate you are using P2P) so by default it will take

control of that system by dynamically assigning an IP address. That is

my understanding but I may be wrong.

I agree it's not much to worry about unless you do browsing and nothing

shows up.

(And you need browsing)



I know I wouldn't lose any sleep over this...



I've seen an issue like this on a PC that the only thing that fixed it

is flattening and starting over.

And that's kind of drastic for this IMO

It has nothing to do with IP addressing, it concerns only the NetBios

browse list.

Are all the machines on the same subnet?

Yes, same subnet. All static IPs.

oh ok

Most people use Logmein free for this..



Since this sounds like a Business. (Remoting in.)

Have you thought about Microsoft Home Server?

It even has a web based Remote Login...

(No Ports to remember and they can access from any Browser.)

If you'd like Image based backups on PC's?

For under 1K it's cheap insurance if you are a business.



Backups are the least thing remembered and with WHS

The backups are automatic...

"Most"?



Maybe in your circle - but I know more that use TeamViewer in my circle.



I know almost as many that use Remote Desktop and Dynamic DNS.



I know some that have setup vWorkspace, but that is geting into the

'business' side of the table..

How To Ask Questions The Smart Way

http://www.catb.org/~esr/faqs/smart-questions.html

 

[Russ SBITS.Biz [SBS-MVP]]

True There are many alternatives

and you are right I should have said something like Logmein.

I personally don't like to put PC's in ANY Environment in a Static IP

configuration



Tools like LogmeIn (Free) allows someone to use a simple web interface

and doesn't require port redirects

Changing the listening ports on PC's

Remembering IP's etc.



I prefer the KISS method of a Business enviroment.



I always try to give clients the options that require the LEAST

amount of administration, since I charge by the hour...



Just creating complex solutions just means more wasted time

and as we know, time=money...



yes it's cool but a good ROI?

With Logmein (Free) or other options if your router dies

You slap a new one in and you are up in 2mins.

With redirecting Ports you have a bit more time involved.



This is also why I suggest Microsoft Home Server

a Simple Solution, for Remote access to desktops

and a VERY Simple solution for Image Backups for PC's



If a Hard drive dies on a Workstation in less than 1hr you can be backup and

running.

Simple!

You say that you are "constantly getting Master Browser errors...".

What does this mean? Is it happening once every day when machines are

booted or is it happening many, many times during the workday, like

every 12 minutes or so?



Can you copy and paste the complete contents of the two errors and post

it with your nest reply? To copy the event click on the clipboard icon

below the Up/Down arrows at the upper right.

This error is occurs when there is a computer on your network with a

misconfigured firewall that does not allow NetBT broadcasts to be

received. The computer with the firewall does not see broadcasts from

other computers so it thinks it's the only computer on the subnet and

self-appoints itself as "Master Browser". As Master Browser, it

broadcasts a message every so often declaring itself as such but since

it blocks all replies, it ignores the presence of the rest of the

network. A legitimite Master Browser will shut itself down after

receiving a couple of these announcements and generate the message

above.



In your case, "COMPUTER1" has the firewall that is ignoring COMPUTER2

and causing COMPUTER2 to shut down as Master Browser.



This is [loosely] covered in the following Microsoft KB article:

"Internet firewalls can prevent browsing and file sharing"





If you can't find/fix the firewall on COMPUTER1, then try setting

COMPUTER1's "MaintainServerList" registry value to "false" using

Regedit as described in the following article then reboot:



"Common causes and solutions of browser Event ID 8021 and Event ID 8032

on domain master browsers"

I think you are correct. I have turned off the Windows Firewall on all

computers and so far no browser errors.

You would think that excluding File & Print sharing from the firewall would

open all ports needed.

So an update.

I have had all the firewalls turned off all day and now I am getting the

8021 error on computer1 (it was previously on Computer2)
