I really hope someone has seen the problem I am about to describe before because I am at my wits end. A couple of weeks ago I had to upgrade a box that ran AD, Exchange 2000, ISA 2000, and Server 2000 that was left over by the previous admin. I know it’s a horrible practice which is why I was upgrading and migrating. Long story short I had to move ISA to a new serve r so I just put ISA 2004 on it. I upgrade the Exchange 2000 and server 2000 to Exchange 2003 and Server 2003 on the original “all in one” box. I have one external NIC facing the internet, and one internal NIC to connect to internal servers. I have all web publishing, ftp, and Exchange publishing rules working inside the network. My problem is that all of the sudden once laptop users connect to the VPN outside of the network they cannot connect Exchange through Outlook anymore. As I said I have created all the necessary rules that are working properly. I even have a domain controller that runs an Antivirus database and pushes updates out to clients, and when a VPN user gets connected it finds the DC virus updater and connects with no problems. It is uses some crazy property port. Mapped drives, and all other resources are available, but Outlook just stays disconnected from Exchange. I can create a new mail profile on my home machine, and the name resolves when setting my domain email account so I know it connects to some extent to Exchange. It will even start updating my newly created mail profile from Exchange. However current laptop VPN users who use it to connect o mail stores can not get connected. I have gotten some outside help consulting help, and I am still stuck. I could go ahead and set up OWA, but I just feel that will only compound the problem because something that should already be working is not. I believe that OWA set up may be futile until I can get this problem resolved. Please anybody that has ran into this problem before can you give me some things to look at as I am stuck without my Sales VPN users being able to connect their Exchange.
