Hi KhB,
If I understand your dilema, this should help...
Even though you are in the directory which contains the file, shown by 'ls <filename>', you still need to tell the shell where the file is by:
1) typing ./<filename>
( the ./ tells it to look in the directory you are in)
2) or adding the nfs mount point to the PATH variable in
your shell environment file. (.profile, .cshrc etc)
3) or typing the absolute path from root to the file.
ex: /<nfsmountpoint>/<filename>
One more little ditty:
Make sure that if it is a binary, you have executable rights to the file.
