Nortel NetDirect VPN Problems on Vista - TapAdapter IP not Assigned
Posting this for consumption by Google, so that when this happens to me again I can search Google and find the answer on my own blog. Then I feel silly. Then I am happy I solved my problem.
NetDirect is a Java based VPN client that requires a the installation of a little ActiveX control and then runs in the systray.
The Problem
I have two computers running this virtually identical Vista configurations. One works, one doesn't.
I'm on Vista Ultimate, and had tried getting NetDirect to work in both Firefox. Essentially, I got to the point where a little popup window opens up, I can see the NetDirect icon in the systray, and the client appears to be starting up. Then I get a long pause in feedback and an error. The output I see in the popup is as follows:
Downloading zip file... Extracting zip file... Loading library... NetDirect: Initializing... [[[ long pause here ]]] NetDirect: TapAdapter IP not Assigned NetDirect: Stopping... NetDirect: Stopped!
At this point the window closes and the systray icon goes away. I tried a number of things including starting the browser "as Administrator" and also had searched Google for answers without any luck.
The Solution
The problem may have been due tot he fact that I already had installed (months earlier) OpenVPN to use a different client's VPN. As I was hunting around the system for the "TapAdapter" mentioned in the error message, I found a start menu option under OpenVPN that said "Delete ALL TAP-Win32 virtual ethernet adapters". Woah - that looked promising!
So I ran the bat file, it deleted some stuff, then I tried starting up the NetDirect connection again. Wham! It worked! Problem solved!
Note: I also started Firefox "As Administrator" when first installing the NetDirect client (it downloads and installs a couple of things). This may or may not have mattered.
