I have just finished setting up a windows 2003 server. It is the only server on the network and is a domain controller.  I have started adding desktop computers to the domain.  Today I found some errors in the event log as follows:

ID: 8003
Name: event_browser_other_master_on_net
MEssage:  the master browser has received a server announcement from the computer (desktop pc) that believes that it is the master browser.

The desktop computer that I added is running windows XP pro. It was never a DC or a workgroup server.  

This problem may have occurred when I was adding a domain user to a security group on the local computer - but the timing may have been a coincidence.

How do I tell the desktop PC that it is not a browser ?

Stop and Disable the Computer Browser service.
I usually do this via Group Policy.

What is the impact on the desktop PC of disabling the computer browser service ?

Is this service enabled by default by XP Pro ?

Do I need to do this for every PC that I want to connect to my domain ?
There is no impact that I am aware of. I have it disabled by default through Group Policy on all the domains I manage. By doing it through GP any machine that is joined to the domain will get the policy which disables the service.

You shouldn't need to do this, in theory at least. The browser service should recognise that the domain controller is the master and stop trying to make itself the master. However in some cases it doesn't (very often laptops that were rebooted at home and come in to the office on "suspend") and disabling Computer Browser is one way of getting round this.

If you do make the change by Group Policy make sure that the domain controllers aren't covered - as they need to browse masters so need their Computer Browser service enabled.

Thanks for the details.  Are you saying that I disable this in the group policy editor on the domain controller ? If so, where. Or is this a policy on the desktop computer ?
No Domain Group Policy. If you are editing the default ones (bad idea but sometimes it has to be done), edit the default domain policy, NOT the default domain controller policy.
