I am trying to install the Exchange 2003 System Management Tools on a server MCS-7825-H2-ECS1 server that is running Windows 2003. I used the Unity Platform Configuration Discs that came with the server to load the OS. When I get to the part to install the Exchange tools, I get the following error when I select "Custom" on the component selection screen - > Microsoft Exchange has a unknown installation problem. I then can not install the tools.
What am I missing that is stopping me from installing these tools? I need them in order to finish the Unity 4.2.1 install.
Thanks for any help you can provide.
