SEPM should have built in sylink replacer utility to replace sylink file after doing 'Find unmanaged computers'
The 'Find Unmanaged Computers' feature allows to push a client package. It would be better if this feature also allowed pushing the sylink file 'Silently'. The SylinkReplacer utility could be used for this. The only problem with this utility is that it brings up a command prompt for about 10 to 15 seconds due to which the users might call their help desk. Sometimes users also close the command prompt window.
