The cerificate status could not be determined because revocation check failed.

Hi we are using exchange 2010 in our setup. we enabled the DAG and configured the  DR site in our setup.

i had recently renewed the   certificate of our Hub server i got the certificate from comodo and do that same. but i forgot to renew it on my DR Site.

1. can i use the same certificate  (which we bought from Comodo)  for my DR.

2. i export the certificate from my Mainsite Hub server and inported the same in our DR Site server. but in the status it shows " The  certificate status could not be determined because the revocation check failed.

if any one help in this regards was very much appreicated.

Thanks & Regards
