1. Querying a remote machine registry using WMI and VB.NET
Hello. I'm not sure if this is the right forum, so please let me know what
is the correct one if it isn't.
I've been puzzled by this a for a few days. I'm trying to read a registry
value from a remote system's registry using WMI (System.Management). I'm
able to connect to the system and even run a process, but I cannot figure out
what is I have to do to get the StdRegProv process. Here is what I am doing:
Dim wmiOptions As New ConnectionOptions
wmiOptions.Username = "username" 'Administrator's login and pwd.
wmiOptions.Password = "password"
wmiOptions.Impersonation = ImpersonationLevel.Impersonate
Dim wmiScope as New ManagementScope("\\" & pAddress & "\root\cimv2",
wmiOptions)
Dim wmiPath As New ManagementPath("Win32_Service")
Dim processClass As New ManagementClass(wmiScope, wmiPath, Nothing)
Dim inParams As ManagementBaseObject =
processClass.GetMethodParameters("GetStringValue")
I know that the inParams fails because I have the Win32_Service, not the
StdRegProv, but how do I get the StdRegProv?
I tried querying instead of instanciating the ManagementClass directly, but
I get nothing returned:
Dim query As New SelectQuery("Win32_Service", "Name='StdRegProv'")
Dim searcher As New ManagementObjectSearcher(wmiScope, query)
Dim envVar As ManagementBaseObject
For Each envVar In searcher.Get()
... <-- There is nothing in envVar.
Next
I am using WMI because although I don't have domain rights to the systems
(otherwise I'd use RegistryKey.OpenRemoteBaseKey...although if anyone can
tell me how to use this with a provided username/password, it would be
great), I have usernames/passwords with administrator rights. I was able to
create a process remotely, so I know that access rights is not the problem.
Any help, alternative method, or pointer to a solution would be appreciated.
