When I tried to sign in MS office communicator 2007 R2 from INTERNAL domain. I amgetting the error " There was a problem in veryifying the certificate. Please contact your system administrator"
Sip changed and certificated issued and assigned to ocs 2007 r2 server . if we install the certificate manually on the client , user can sign up successfully .
my question why domain joined client couldnt get the certificate , how to solve it.
thank you
