cool!! I was using a text file with all the computers in it, instead of \\* i was using \\@text.txt
But still i have a question, why do you use the -c switch?? you give the unc path fior the lsclient.exe file in the command so there is no need to copy it since it'll be executed from that share....this way you'll be running this a little faster 🙂
\\servername\share\psexec.exe \\* -u "domain\username" -p "password" \\server\share\lsclient.exe "name of server where lansweeper resides"
