If you receive the subject event, try the following workaround:

1. Use Regedt32 to navigate to

        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

2. Add two Value Names as type REG_DWORD entries:

        MaxFreeConnections and set it to 8.

        MaxWorkItems and set it to 255*.

3. Turn off Autodisconnect by setting it to 0xFFFFFFFF.

4. Shutdown and restart your server.

*MaxWorkItems has a maximum value of 512. If you still receive the subject event, try 383, 447, 479, and finally 512.
