I tried deleting the registry settings twice but still no luck - also reset all the browser settings to the defaults, and added the server to the Trusted Zone, and no change.
Do agree though that it is probably a network configuration problem - just can figure out what though.
I've included the full SylinkMonitor log.
Thanks
PS. Shield is just yellow with no dots or warnings
