Is there a fix available for Windows 7 clients trying to connect to Direct Access and receiving Error Code: 0x643 IPTTPS interface creation failure?
I see a similar thread on TechNet but no solution: http://social.technet.microsoft.com/Forums/forefront/en-US/faf315c2-b04e-463f-8bc9-c47b7430016d/directaccess-iphttps-interface-creation-failure-0x643?forum=forefrontedgeiag
Also, there is a hotfix availave for Windows 8 clients but not Windows 7.
