cannot run exe along psexec.exe
Is your solution to the EXE not running under the System account to run it using PSExec so that you can pass alternative credentials? If so, why not simply use the 'RunAs' command?
If you're trying to run the EXE on a remote machine, you need to specify its name on the command line.
>my exe does not run in system account
Really? It must be pretty unique, then!
