Comments
The KB article referenced in the message does not exist nor is there any reference to this event anywhere in Microsoft’s KB as of this writing (it is in the works however). The issue was seen on a Win2k PDC and can be caused by any of the following:
1. Installing security patch MS04-044 or its superseding patch MS05-011.
2. A master browser announcement packet storm.
The issue is resolved by adding the following DWORD registry key, which is also not documented anywhere: “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MRxSmb\Parameters\[MaximumMasterAnnouncementsQueueSize]=<value>”.
The default <value> is 150. Increase this value based on how large your network is or until the event ceases. For example, a very large company may need to set this to 2000 or above.
