One should rather use the admin$ share for the unlikely case where the system directory is not C:\WINNT.
Additionally, one should put the files to search for into an array and then check each array element. This will make it easier to add additional files to check for further down the road.
Also, using e.g. the COMNetView() UDF would improce the script in such a way that it'll check all computers registered in the domain.
