Question : Event Log - Schannel  Event ID: 36888

I am in the process of setting up a Microsoft TMG Enterprise server on a new Dell PowerEdge R610

I have installed Windows Server 2008 R2 Enterprise, Exchange 2010 Edge Transport Service, ForeFront 2010 for Exchange and finally TMG 2010 as per the TechNet TMG installation guides.

This is the first TMG server I have setup with the Exchange Edge Transport Service.

Around the point at which I installed Exchange 2010, the system event log started filling up with the following entries:

Source: Schannel
Event ID: 36888
User: System
Message: The following fatal alert was generated: 10. The internal error state is 10.

TMG seems to be working correctly - proxy, web filtering, server publishing etc

I have installed two SSL certificates - one was requested from our internal certificate server and I have Exchange enabled that certificate for SMTP.  The other certificate is our public SSL certificate we use for website publishing - and ultimately SMTP but in case their were problems with the intermediate certificates I haven't yet enabled it for SMTP.

I'm having trouble finding any useful information about the Schannel error - can anyone help.

Thanks.

Answer : Event Log - Schannel  Event ID: 36888

The issue appears to be related to the latest broadcom drivers supplied on the Dell install CD (v6.2 i think), installing older drivers fixed the problem.

Note: I had to reinstall (again - 4th time) using an older Dell install CD - if the new drivers were ever installed on the system the errors would not totally go away, even if the drivers were down graded to an older version.  odd.
