NET TIME as service not working

[creeping]

The following code works as a program, but not when I install it as a service using srvany and instsrv.

Any ideas on what I need to change to get it to work. Im guessing it has something to do with the system account running over the network.

Thanks

$sTimeServer = 'server'
$sTimeCmd = 'NET TIME \\' & $sTimeServer & ' /SET /YES'
$iDelay = 1000 * 60 * 5

While 1
    Run(@ComSpec & ' /c ' & $sTimeCmd, '', @SW_HIDE)    
    Sleep($iDelay)
WEnd

To answer my own question:

RunAsSet ( ["user", "domain", "password" [, options]] )
