Hello All,

I am trying to install Exchange 2007 Std Edition along side my SBS 2003 server:

Here's my current setup:

Server 01: Small Business Server 2003 (Service Pack 2, Exchange 2003 with SP2)

Server 02: Additional Domain Controller (Windows 2003 Server R2 Service Pack 2)

Server 03: Member Server ISA 2006 (Windows 2003 Server R2 Service Pack 1)

Server 04: Member File Storage (Windows 2003 Server Service Pack 2)

Server 05: Member Exchange 2007 (Windows 2003 Server x64 Service Pack 2)

When I go to setup the new server I get the following error message:

All my servers are running at least Service Pack 1 and most are running Service Pack 2 as you can see above!

The new Exchange 2007 Server I have even made an additional domain controller which is still producing the error message in the error above!

I have tried clearing the userprofile and logs to see if this fixes the problem it hasn't!

How do I go about fixing this problem?

Thanks

Ben
