Event ID 36887 and 36888 Schannel errors on my ForeFront TMG proxy server

Hi ,

Found alot of ( Event ID 36887, Source Schannel:The following fatal alert was received: 0. and

Event ID 36888,Source Schannel: The following fatal alert was generated: 10. The internal error state is 1203. )

on my forefront TMG proxy server running on windows server 2008 standard edition. The event logs occurred 5 minutes one time.

Is it related with Certificate issue ? We are just using self assigned Cert and we don't have CA.

Or it is caused by SSL handshake error ? Cause of 1203.

It is save to disable the logs in registry ? Any suggestions will be helpful.

Thanks .,,
