I've setup a Windows Server 2003 Std domain running Exchange server 2003 Std. Now I'm setting up a second site (not in the same city) and want to have it use the same Exchange Server for email. It will also be running Windows Server 2003 Std. Is it possible to have the second site use the original site's Exchange server for email? I think it would require setting up a domain trust for authentication purposes but I've never dealt with this before. I'd appreciate any info. Thanks
