Hello All- Has anyone run into this particular problem before? I'm trying to publish an RD Web Access site using TMG. I've configured RD Web Access on an internal server and it works internally. (Although when connecting to it I get a certificate error. I can connect anyway.) I can't connect to it externally, though. I get this error: "The certificate chain was issued by an authority that is not trusted. (-2146893019)" I've tried buying a new cert (from Go Daddy). I followed the certificate installation instructions to the letter, including installation of the intermediate certificate, on both the TMG server and the internal server that is hosting the RD Web Access site. But when I do "Test Rule" on this rule, it tells me: "0x80090325 - The certificate chain was issued by an authority that is not trusted." It suggests I see go.microsoft.com/fwlink/?LinkId=115965. All that says, though, is that I need to "Import the CA certificate." I thought putting in the intermediate certificate did just that. I have four other Go Daddy certs on the TMG server and they all work normally. I've Googled these errors and mostly found the same advice, to install the CA certificate. Any hints? Should I talk to the Go Daddy folks? Thanks, Rob -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Rob Moore Network Manager 215-241-7870 Helpdesk: 800-500-AFSC
