Event ID: 2027 Source: Srv

The server has detected a potential Denial-of-Service attack caused by consuming all the work-items. Some connections were disconnected to protect against this. If this is not the case please raise the MaxWorkItems for the server or disable DoS detection.
This event is due to overwhelming request on a Windows server that it cannot handle. In some cases, the system locks up and the only way to get to it is to reboot. You need to make a registry entry for MaxWorkItems. Always check Microsoft Technet for this kind of issues. Using regedit, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters, right click, choose New, click DWORD Value and enter "MaxWorkItems". Double click it and choose decimal under the Base option, and put a value data between 1 and 65535. Microsoft advices using 4096 and doubling this value until the server's WorkItemShortage is below 3 (this can be monitored with Microsoft performance monitor Server\WorkItemShortage).

Note: Registry modification is at your own risk. Always backup your registry before making any changes to it.
