Can anyone help with the following? When I install OpenVPN on Windows Server 2003, it warns me that "TAP-Win32 Adapter V9" hasn't been tested on this version of windows, but I try it anyway. However, that does seem to be where the problem is. When I try and connect as a client to an OpenVPN server installed elsewhere, the "TAP-Win32 Adapter V9" network adaptor fails to pick up the IP address which is assigned to it by the VPN server. The log file starts out as follows:
Wed Dec 12 14:28:32 2012 OpenVPN 2.2.2 Win32-MSVC++ [SSL] [LZO2] [PKCS11] built on Dec 15 2011
Wed Dec 12 14:28:32 2012 IMPORTANT: OpenVPN's default port number is now 1194, based on an official port number assignment by IANA. OpenVPN 2.0-beta16 and earlier used 5000 as the default port.

The route addition failed: Either the interface index is wrong or the gateway does not lie on the same network as the interface. Check the IP Address Table for the machine.
with the last line repeated a few times before the log gives the routing table, followed by all the adaptor information. Instead of a DHCP IP/netmask of 192.168.233.6/255.255.255.252 (as mentioned in the above log), the "TAP-Win32 Adapter V9" adaptor always has 0.0.0.0/0.0.0.0, and the status is always "Acquiring network address".
How can I get round this? Are there any manual configuration changes that I can make to solve this?
Thanks vm, Paul
