I am trying the following command
"psexec -s -d -i 1 \\<machine-ip> -u Administrator -p <pass> notepad.exe"
&
"psexec -i \\<machine-ip> -u Administrator -p <pass> notepad.exe"

Returns :
PsExec could not start notepad on <machine-ip>:
The system cannot find the file specified.

Setup: local machine: win Serv 2008 & win 7 U, remote machine : win xp pro sp3 (I have administrator privilege on all systems)

I found out that psexesvc.exe (psexesvc service) is not getting copied to and started in target machine  (C:\Windows\)

Any solutions ??
