I am unable to connect my Lync 2010 client from an external non-domain PC. Internal, in the domain works fine.
When I try to connect with auto-config, I get the error "There was a problem verifying the certificate from the server.". A look at the System Log shows that the client is looking for sipinternal.consoltechlab.com as well as sipexternal.consoltechlab.com on the certificate.
When I try to connect with a manual config, setting my external server name/IP address to access.consoltechlab.com, I get the error "Cannot sign in because the server is temporarily available". I have also tried access.consoltechlab.com:443.
Some additional details:
- I have a public SRV record in place for _sip._tls.consoltechlab.com, that points to access.consoltechlab.com.
- There is an "A" record in place for access.consoltechlab.com. It is the IP address of of the external interface of my Edge server.
- My Edge server's external interface is direct on the internet, with no firewall. Just the Windows Firewall, which has the necessary ports open.
- I have exported the root CA cert of my domain as well as the front end server's cert to my home PC.
I have attached to log file from the Lync client. Any help would be most appreciated. Thanks.
