I have installed and configured server 2003 standard, installed AD and configured DNS and have all my staff linked and GP's created, My domain is for example [example.com] but our email is [example.net] and we installed exchange 2010.  We had a valid SSL for OWA when we were on on exchange 2003. We now cannot get an SSL now that we are on exchange 2010 because we do not own the example.com domain.  It has been recommended that we rename the internal domain to example.local that way we ca get an SSL for the example.net which we do own.  Can i change to DC to [example.local] or just somehow redirect the requests to the a SSL that will work other than changing the host files on all the computers?

Unfortunately the domain rename is not supported with exchange 2010

http://technet.microsoft.com/en-us/library/cc816848(WS.10).aspx

The domain rename operation is not supported in Microsoft Exchange Server 2007 or Exchange Server 2010. DNS domain rename is supported in Exchange Server 2003. However, renaming of the NetBIOS domain name is not supported in any version of Exchange Server. Other non-Microsoft applications might also not support domain rename.

Not sure on the redirects

Thanks

Mike

I'd go with a new cert. changing domain name is not easy , it's a big project by itself.

Domain Rename is not supported in any version of Exchange other than 2003.

Check out my guide here on domain name choice: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2370-Exchange-DNS-Configuration.html

The only option you have is an inter-org migration.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

correct.

You can use ADMT to migrate your users, computers and groups over to new hardware/domain if you have it: http://www.microsoft.com/downloads/en/details.aspx?familyid=6D710919-1BA5-41CA-B2F3-C11BCB4857AF&displaylang=en

or use a ISA/TMG infront of your domain as a proxy.
