When installing Exchange 2007 on Windows Server 2008 R2 (probably the same error exists on Windows 2008), you get error that doesn’t contain descriptive information:
The system cannot find the file specified
An unexpected error has occurred and debug information is being generated: The system cannot find the file specified"
What you need to do is run:
ServerManagerCmd –i RSAT-ADD
In Windows 2008 R2 you run:
- Import-Module Servermanager to load Server Manager modules
- Add-WindowsFeature RSAT-ADDS
