Event Details

Product: Windows Operating System
ID: 834
Source: Microsoft-Windows-TerminalServices-SessionBroker
Version: 6.1
Symbolic Name: EVENT_FILTER_PLUGIN_INVALID_PRIORITY
Message: The %1 plugin has an invalid sub key in the registry. Sub key for this plugin should be a positive integer that determines priority for that plugin (order in which plugins are called by the RD Connection broker). Please check the registry value for this plugin.

Resolve

Change filter plug-in priority to a positive number

The filter plug-in priority must be a positive integer and is set by using Registry Editor. The registry path is as follows: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tssdis\Parameters\Filter\<priority>, where <priority> is replaced with a positive integer.

Verify
