This error is not the cause of your problem.

Is this event repeating it slef over and over?  If so make this change

Go into the registry to the following key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL

Create a DWORD value and name it "EventLogging" (without quotes) with a value of "0" this will eliminate such event log messages. The error may still occur but without a log entry being generated.


Restart and try again.
