When attempting to connect to Pangea, the connection application will spit back an Error 86 (network password incorrect).

Solution for Windows 7 Professional
To solve this you will need to edit a Local Security Policy and set one of the entries to something other than “Not Defined” as it is on default.

First, enter the control panel, and in the top right, under ‘View by’ select ‘Large Icons’.  Now choose ‘Administrative Tools’, and then select ‘Local Security Policy.’  A new window will appear and then choose ‘Local Policy’ on the left, then ‘Security Options’.  You will now have a large list of options in the right side of this window.  Scroll down to the entry for ‘Network Security: LAN Manager authentication level’ – You will double click on this choice and change the drop down menu item from ‘Not Defined’ to ‘Send LM & NTLM – use NTLMv2 session security if negotiated’.  Now simply click the ‘Apply’ button.

Solution for Windows 7 Home Editions (Starter, Home Basic, Home Premium)
This is a little trickier than the Professional fix.  For this you will need to edit the Registry by creating a DWORD in the location for:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa

The DWORD should be called LMCompatibilityLevel and it needs a value of 0

I am purposefully leaving out some details about how to implement this solution as errors in the Registry due to improper editing can render your computer crippled.  If you are comfortable in the Registry then this will make sense and you can edit this as you see fit.  If not, find someone that is or contact CNSIT.

You should now be able to connect to Pangea.  Enjoy Windows 7!
