Force Install Application Outside of GPO

I need to install VNC on many computers but need to be able to push it out on demand outside of GPO. I can't wait for user's to logoff/ logon. What's the best way to do this?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

How many is many?

Most of your options are not free, integrate with AD, or require installation of a client.

Are the machines even on,nsince you can't wait for user logon?

About 200. I may just use GPO and then SpecopS GPupdate to mass reboot them.
Using group policy would be the easiest if possible.  Plus, it's free.

I didn't think VNC required a reboot after installation.  It is normally available immediately after installation.
Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

You will need to script this and it can get confusing.

You will need to have the script Ping for availability {True |False}
If True copy files to a temp locations on the host computer.
Then you will need to start a remote process running the command line for vnc silent install on the host computer.

'Reads Line by line host name and passes to *
'Ping Function                              *

Const ForReading = 1
Const ForWriting = 2

Set objShell = CreateObject("WScript.Shell")
Set objFSO = CreateObject("Scripting.FileSystemObject")
strHostFile = <Enter the text file that contains your computer names>  'Line needs to be edited for your environment 
set objTextStream = objFSO.OpenTextFile(strHostFile,1)

Do Until objtextStream.AtEndOfStream
strcomputer = objtextStream.Readline

	blnping = PingHost
	If blnping = true then 
	end if


'Pings the host to see if it's available  *

Function PingHost

Set objShell = CreateObject("WScript.Shell")
Set objExec = objShell.Exec("ping -n 2 -w 1000 " & strcomputer)
strPingResults = LCase(objExec.StdOut.ReadAll)
If InStr(strPingResults, "reply from") Then
  PingHost = True
wscript.echo "True"
	PingHost = False
wscript.echo "false"
End If

End Function

'Remote install                             *

Function RunInstall
strCommand = "calc.exe"  	'Change the Exe that you want to run
				'Leave Calc.exe for testing

Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set objProcess = objWMIService.Get("Win32_Process")

errReturn = objProcess.Create(strCommand, null, null, intProcessID)

If errReturn = 0 Then
Wscript.Echo "notepad.exe was started with a process ID: " & intProcessID
Wscript.Echo "notepad.exe could not be started due to error: " & errReturn
End If
End Function

Here is another option

this is a little web demo

The app they use is call FastPush from

Just one more

Sysinternals is a great source for a plethora of utilities
Here is a link to PSEXEC  and should work really well. 

I like this one because it is backed up by MS.

Poor answers, most likely my question was poorly posed.

I object with the reason for deleting this question.

I think I understood your question pretty clearly .
You want a solution to push applications to machines without having to use GP log on or logoff scripts.

I gave three very viable solutions outside the scope of using GPO.

Did you even read any of my suggestions?

PSEXEC will accomplish what you need, but I am not going to look or search for VNC's install switch variables.
This is something you should find on your own.
DarthRaterAuthor Commented:
I stand by my request to close based on poor responses. I read all your suggestions but they are neither scalable nor feasible for the workload I have in front of me. It just isn't a solution that I can award points on. I also mentioned a reason for the closing that my question was also posed poorly.

You are saying that you cannot stage 200 machines to install VNC silently using any one of these solutions.
What do you want done. A snap of your fingers and poof all machines patched.

What angle are you think of.  Please enlighten us on this.

I gave you a VBS that will ping a list of computers then if they respond the install starts.
The second one seems pretty nice, but I have not tested.
The third I have used multiple times to patch or install on environments that are your size.

The other option is what awaggoner suggested, but sort of not truly address your question.

If feel you are in the wrong by saying these are poor solutions.  

So when a moderator reads these replies I hope he stands his ground with asking you to reward points where they are due.
I spent time putting the script together for you as well as giving you a couple of alternatives.
