I tried all the suggestions above, but what worked in the end was changing the Application Pool managed pipeline from Integrated mode to Classic mode.
It runs in its own application pool - but it was the first .NET 4.0 service - all other servicves are on .NET 2.0 using Integrated pipeline mode. Its just a standard WCF service using is https - but on Server 2008 (not R2) - using IIS 7 (not 7.5) .
