Question

Remotely install software using WMI

Asked by: qwertypal

Hello!

Have the following problem I can't find a solution to...

Computer A remotely needs to install software on Computer B.

I have the following environment:

1. Software installation requires admin privs
2. Computers are part of the same Workgroup (not Domain !!!)
3. Computers have same admin account names (Admin) with the same passwords
4. Computer A logged on and runs under Admin account
5. I do not know Admin password

Can I somehow install this software using MSI ??? or any other technique without knowing the Admin password ???

Tried the script below but on line

      Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\CIMV2")

got Access Denied error...

Thanks.

On Error Resume Next
strComputer = "comp-a"
	
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\CIMV2")
	
Set objSoftware = objWMIService.Get("Win32_Process")
	
Res = objSoftware.Create("msiexec.exe /i C:\orca.Msi /qn /l*v C:\InstallORCA.log", Null, Null, PID)

how remote are the computers from each other?

would it be possible to resolve the "5. I do not know Admin password" ?
the password reset takes about 3 mins:

Well, comps are located within one building. We didn't want to store Admin password anywhere in the system to compromise all computers

The problem is that we have N number of comps on one Workgroup, which were set up with the same admin login and password. And now they all have to be updated with software that requires admin privs. Why they are not in a domain, I've got no idea. What are my options? Could it be done without knowing the admin password?

Here ia a solution for somebody how is interested. Impersonation works even for workgroups.

Here is the list of requirements to set up Computer B if it is a Win XP Pro. It doesnt work with Win XP Home.

1. Have same workgroup name on both comps
2. Go to Local Security -> Local Policies -> Security Options ->
Network access : Sharing and security model for local accounts = Classic...
3. Turn off or reconfigure firewall to allow RPC

Thank you all !
