I have a new Forefront TMG 2010 server. It is running all current updates. A few days ago I established a secondary network object 'Cafe' and duplicated the web publishing rules. I literally copied and pasted the existing rules and only changed the source network. There were also some updates to a test IPSEC vpn.

We began receiving SCHANNEL errors, events 36887 and 36888. The frequency of these alerts has increased to almost exactly once every 10 minutes.

How can I proceed to eliminate these errors?

From what I can find it has to do something with an SSL Error, maybe a certificate that is being used? Is both servers  authenticating via certificate, I would check the certificates

Rsoy777, good point. I'm using shared secrets for my VPN tunnel.

In the end it turned out to be a problem with having multiple certificates installed that all provide the server authentication function. It's apparently a known bug and can be safely ignored.
