Hi

My company recently had to update our web cert with geotrust and the format was webmail.mycompany.com
however we had some internal dns names linked in with the cert and due to legislation we were told that internal fqdn were not allowed. we now have all over the place the following error ( picture attached).
External access to the email server is fine but the errors are all internal.

Help Would very much appreciate instruction on how to maybe reissue the internal certs ..

Hi TrenchControl,

Check out my article here. It discusses how to renew a certificate without the .local FQDNs, how to configure split-brain DNS to work with the new certificate requirements and how to modify all the necessary Exchange URLs to reflect this new requirement.

Hi

So if i have an exchange server called exchange1.mydomain.local and i create an A record on my my domain called exchange1.mydomain.com and do the active directory migration and hey presto. Will my Cisco router have problems with this ? does all the traffic route out through the firewall to get back in ?
Thanks
