I recently took over this organization and now installed a brand new exchange 2010 in a 2003 Active Directory forest domain. The issue that I noticed is that the DNS name space and NETBIOS name of active directory in this organization is called "domain.ad" and the external FQDN for the exchange is "mail.domain.com"
When I requested a UCC cert which includes the internal FQDN of the exchange server, the authentication failed as .ad is owned by the country Andorra. In order for me to get a .ad external domain the requirement is that you are a local resident for that country.
The question I have are the following:
1) I cannot rename the active directory dns name or netbios name with rendom.exe as there are too many services such as Microsoft Lync 2010 running in the organization
2) What is the recommended way that I get the UCC issued. Can I just add the NETBIOS names and for the external domain just create a split DNS?
3) The UCC i ordered is for 10 domains as I will be installing two more exchange servers in different sites, how would this impact the cert?
Any help would be appreciated.
