I've been trying to install Exchange System Manager 2003 on my Windows Server 2008 box for a bit and am unable to find a solid solution. I downloaded the tools for Vista and thought they would install by default but no luck. After some advice from another forum i stripped out 2 lines in the MSI with Orca. Tried it and it worked for me if I deleted the following entries in the InstallUISequence table: * CA_SET_ERROR_MSG * FatalErrorDialog The install did go fine but in Active Directory Users and computers there are no exchange tabs or tasks available. Can someone shed some light on this for me?
