psexec running script on remote machine from share

I have psexec which I want to use to make a remote machine run a script from a share.

command I'm using is;
psexec @e:\wsus\scripts\test_servers.txt \\server\share\script.vbs

I  get an error stating The System cannot find the file specified.

I've verified the path is correct.

Because it's a Network share, do I need to specify a username and password even through the share and security permissions are set to allow everyone to read the files?

Alternitively, could psexec send the file to the remote machine and then kick it off?  I've read about the -c command but never managed to get it to work

Thanks
