Hi lafcu,
The primary function of the browser service is to provide a list of computers sharing resources in a client's domain along with a list of other domain and workgroup names across the wide-area network (WAN). This list is provided to clients that view network resources with Network Neighborhood or the NET VIEW command.
Description of the Microsoft Computer Browser Service
Please refer to the following steps:
1. Within that log, identify the “computerMAIN721” that is announcing itself as a master browser.
2. Go on to the computer identified in step 1, go to the Services Administration panel. You can usually find this by going to Control Panel -> Administrative Tools -> Services.
3. Once you have Services open, look for an entry called “Computer Browser”. If that service is “started, ” you have found your culprit. If not, you may have to try the registry hack listed in step 6.
4. Double click on the “Computer Browser” service to edit it. Stop the service and then change the type to „Disabled” (from either Manual or Automatic). Click OK to apply your changes.
5. That should have resolved the issue. You should check your event logs periodically to be sure that the error does not show up. If the error continues to appear read step 6.
6. Check the following registry value on the computer: "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters\IsDomainMaster".
Ensure that it is set to false. You probably have to reboot the machine to make the change take place.
Note: Lets take a registry backup before making and changes in the registry.

Candy

Hello Lafcu,
This error that you have received is a common error.
Actually when any machine in the network fails to get the list of the all the computers then it assumes that the master browser is not working and start anouncing in the entire network that the master browser is not working and he forces for the election and frankly speaking wanted to become the master browser.
Master browser maintains the list of computername and IP address.
This is a part of networking which helps to reduce the network traffic.
In the netwok all th machines keeps the Netbios name (computer name) and the IP address of the neighbour machines.
Please ignore if the error is not repating any more but if the error is continiously repeating then its a problem and can't be ignored.
1) If the error is repeating stop the master browser service on the server which is trying to become the master browser(check the alert )
2) You may also need to change the registry -
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters\IsDomainMaster".
set to false
3) If still it is repeating , then on the server run ping IP address -t in the loop to find any network problem is there or not. (check if the packet is dropping , ping the server from different server)
- Contact your networking team to check the setting on the switch / router to trouble shoot the issue.
Note - If the error occurrs continuosly then the server may marked as bad workstation and will start reboot abnormally so try to get rid of this error asap.
