You can restore lost/missing functionality to the SS 4.5 console by running SBSSETUP.EXE /REINSTALL from the SBS 4.5 CD3. This replaces most files in the %SystemDrive%\SmallBusiness folder and the Html sub-folder. The reinstallation performs the following tasks:
Verifys and overwrites all the above mentioned files.
Unregisters and re-registers all controls.
Renames the following files:
%SystemDrive%\SmallBusiness\Scw.ini to Scw.old.
%SystemDrive%\SmallBusiness\Template\Clioc.inf to Clioc.old.
%SystemDrive%\InetPub\Wwwroot\Intranet\Default.htm to Default.old.
%SystemDrive%\InetPub\Wwwroot\Default.htm to Default.old.
Backs up the registry. The SmallBusiness key is renamed to SmallBusinessOldx, where x is a sequential number between 1 and 20 (the maximum number of times you can do this).
Resets the access control lists on all the files and folders listed above to their default settings.
NOTE: You must shutdown and restart the SBS computer.
