Thanks for commenting all! I found out how to do it, and this is the completed code:
$user = "youruser"
$p = Read-Host "Enter domain password for $adminuser"
cls
$expression1 = "enable-psremoting -force"
$commandBytes1 = [System.Text.Encoding]::Unicode.GetBytes($expression1)
$encodedCommand1 = [Convert]::ToBase64String($commandBytes1)
$expression2 = "Set-ExecutionPolicy remotesigned -Force”
$commandBytes2 = [System.Text.Encoding]::Unicode.GetBytes($expression2)
$encodedCommand2 = [Convert]::ToBase64String($commandBytes2)
$expression3 = "Restart-Service winrm”
$commandBytes3 = [System.Text.Encoding]::Unicode.GetBytes($expression3)
$encodedCommand3 = [Convert]::ToBase64String($commandBytes3)
foreach ($server in (get-content c:\temp\enablepsremotinglist.txt))
{
echo " "
echo "Running on $server"
echo "--------------------------------------- "
echo " "
psexec.exe \\$server -h -u no\$user -p $p cmd /c "echo . | powershell -EncodedCommand $encodedCommand1"
psexec.exe \\$server -h -u no\$user -p $p cmd /c "echo . | powershell -EncodedCommand $encodedCommand2"
psexec.exe \\$server -h -u no\$user -p $p cmd /c "echo . | powershell -EncodedCommand $encodedCommand3"
}
I hope this can be of help to someone else one day:)
PS: Please keep in mind that this send your adminpassword as clear text..
