Problems with SSL VPN on SBS 2003 domain need users to install .dll files in IE8

Last Modified: 2012-05-07

I recently bought a netgear SSL312 VPN concentrator to allow the users of my SBS 2003 domain to get VPN access to our LAN.

Part of the attraction of buying this box was that users could use a browser to establish a vpn connection. Once authenicated an icon would appear in their system tray and providing they keep the browser open then a SSL VPN tunnel would be established. This system requires that certain active x controls be allowed in order for some software to be temporarily installed on the system

I have setup the unit just fine and have set it up to use kerberos to authenticate my users. When I log into the unit from my computer at home (non-domain) I can successfully authenticate on the box and connect to the domain. I cant do much else because my computer is not part of the work domain.

My problem is that when I try to estables a VPN tunnel using a client machine the active x control will not install on the system and therefore no VPN access can be established. I have followed netgears advice on which active x controls to allow and it still wont work. Fearing that it might be somthing to do with IE8 I have tried using Firefox and got the following message:

Windows registration faliure or could not perform copying files

 It should be noted that I can authenticate just fine when I am using domain admin credentials.

What I think is happening is that my domain users arent allowed to install software onto their machines and this is causing the issue.

Netgear tell me that I need to be able to run a .dll file in order to get the tunnel working. This is installed in the active x control.

Does anybody have any suggestions?

Much appreciated.
