How to disable CRL check in Communicator 2007

by  computerhighguy  Posted    (Edited  )
If Communicator 2007 cannot get to the CRL distribution point for the ceritificate (Details Tab --> CRL Distribution Points on the Root CA certificate), it usually won't log in. This most commonly is an issue when you are using an internal CA that is either offline or firewalled off.

Disable CRL checking on Office Communicator Client:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Communicator\CertificatePolicy
Set EnableCRLChecking = 0 (if does not exist, please create a DWORD value.)
Restart computer to take effect.
