Intranet names not allowed as SAN in certificates anymore

Hi, I recently bumped into this problem whereby I tried to purchase a new multiple domain certificate for a client who's exchange 2007 server is currently running with a single name cert (which is causing cert warning pop-ups for internal users). So I figured I'd purchase a 3 year multiple name cert and include the local name of the server exchange07.domain.local only now I find you are no longer allowed intranet names on a cert. So... how do I get around this issue as we look after various SBS2008/11 and exchange 07/10 boxes that will come a cropper when their cert expires.

There is no need for the internal name on the certificate. With SBS, the setup wizards configure Exchange appropriately and create a split-DNS zone automatically so internal clients n external clients all use the same URL, which is not an intranet name.

If the wizards were skipped, or in non-SBS environments, you will want to replicate that environment using the same methods. Set up the various exchange URLs to use an externally valid name and create a split DNS zone (if necessary for your topology) so the external name lookups return the internal IP address while on the LAN.

When properly configured, clients will not get an internal name and will not throw a certificate warning,
