Re: pywintypes.error: (5, 'OpenEventLogW', 'Access is denied.')

OK , let's explain the case


My goal is to read the event log of the remote windows machine.
I have experienced the wmi library, the wmi problem is that I have to create parsers, I have not found any code.
On the remote machine I have no authentication problems as I connect to the local network.
the only question now is how i have to do? before call
 hand = win32evtlog.OpenEventLog (server, logtype)
maybe i have to create an authentication contex? i'am not skilled in that.

Tim noted that the issue is what permissions you have on the *remote*
machine - having the username and password of the local machine means
nothing to the remote machine you are trying to access.

Tim also suggested a specific experiment you should try - did you try
it? What happened?

(To put it another way - the issue is not about your code, nor about
your account on the local machine - it's about your permissions on the
server. The server apparently does not trust either your local machine
or the account you are using on your local machine)

Cheers,

Mark
