Hello list,

We have been using OpenVPN for a long time now, and recently introduced
2.0 and certificates besides our existing 1.6/shared-keys infrastructure.
This has mainly been a snap and it works like a charm for the two clients
I connected upto now on 2.0.

The third client however, gets the following error in his log:

Thu Jan 06 11:31:23 2005 us=174944 PUSH: Received control message:

I cannot find anything on Google about this, anyone have any idea what's
wrong? I can post the config if needed, but I don't think it has much
relation to this error. The same config and certificate work on other
machines.

That usually means that an other openvpn process is already running using the TAP interface. If this is intensional you can create a second TAP interface from the Start-menu.


Check in the Task Manager if there is any other openvpn processes running. Perhaps the OpenVPN Service has been started by mistake.
