               Good morning,

               I fear the answer to this is that I just cannot do this....

               I wrote a python script that goes out to a bunch of remote
               machines and queries the registry for some values.
         Effectively,
               there have been some software upgrades that have been done as
               the need arose but we need to do them across the organization
               now.  There are three, and the script checks all three and
               returns the values.  One of these just needs to be a registry
               change as it is a client server application that the
        server was
               upgraded and the clients need a change to a registry
        value to work.

               Long story short, I am using _winreg to do this.

               hKey = _winreg.OpenKey (keyPath, path, 0,
        _winreg.KEY_SET_VALUE)
               value,type = _winreg.QueryValueEx(hKey, item)
               if (value == wrongValue):
                     _winreg.SetValue(hKey,'',_winreg.REG_SZ,correctValue)

    Hmm. If you're querying with (hKey, item), shouldn't you also be setting
    with (hKey, item), not (hKey,'')?


               When I do this I receive the error:

               _winreg.SetValue WindowsError: [Error 5] Access Denied


               I am running this from my machine as a domain admin,
        connecting
               to the remote machine which is also on the domain.
               I am connecting to the remote registry with:

               keyPath = _winreg.ConnectRegistry(r"\\" +
               ipAddress,_winreg.HKEY_LOCAL_MACHINE)


               Thanks for any help.

           What is 'ipAddress'? Is it an actual IP address? The
        documentation says
           it should be the computer name.

        Thanks for the response.  From my experience that does not
        matter.  It is an actual IP address.  I can connect to the
        registry fine, its just the writing.  I read that value and
        other values.  It errors on the _winreg.KEY_SET_VALUE.  I am
        wondering if Windows just will not let the registry be changed
        remotely in this way or if there is something else I have to do.

Sorry, that line is correct, I was removing specific information relevant to our infrastructure. That is the valuename. The error I am getting is:

Traceback (most recent call last):
  File "script.py", line 53, in <module>
    value,type = _winreg.QueryValueEx(hKey,item)
WindowsError: [Error 5] Access is denied

But the real error is here I believe:

       hKey = _winreg.OpenKey (keyPath, path, 0, _winreg.KEY_SET_VALUE)

When I just do a:

       hKey = _winreg.OpenKey (keyPath, path, 0, _winreg.KEY_READ)

I receive no errors.

Thanks.

If it's complaining _as soon as_ you request write permission then I'd
say that was a permissions problem, not an error! :-)
