Does the FQDN on the certificate match the FQDN of your server?

On setup it autmatically creates a certificate publishing.mydomain.com. However I wish to use the certificate I'd purchased from an external certification authority (Comodo Group). After I have installed that certificate to my web server in IIS 6.0 I can no longer browse the public folders in Exchange System Manager, when I do I get the following message:- The token supplied to the function is invalid ID No. 80090308 Exchange System Manager I keep getting that message, even if I clear the Require Secure Channel(SSL) box in Directory Security for the Exadmin folder within IIS. The only way I can browse Public Folders again is to remove my external certificate and Select Assign an existing certificate, then re-assign the publishing.mydomain.com certificate. Any ideas on how I can use my external certificate and still browse Public Folders in Exchange System Manager ? Many thanks in advance.
