Windows VPN Connection Setting Instructions

Windows 2000 users only!

Windows 2000 requires a Registry edit to enable L2TP/IPSec to interoperate with Purdue's VPN servers. This is documented in Microsoft Knowledge Base article 310109. You can set the appropriate Registry settings by clicking here. After you download the file, unzip the .reg file and double-click it to merge the entries into your Registry.

After adding these entries to your Registry, you must reboot your Windows 2000 system for the change to take effect. Then continue with the instructions below.

Note that some dialog boxes may appear different from those shown here.
