Hi All, Does anybody knows how to install Certificate Authority in 2 node Active/ Passive cluster exchange server 2003 for secured Outlook Web Access? With thanks in advance, Sanjay

Hi, Installing a CA on the cluster is not needed. First install a CA on a server (often a DC is a good place). See here: http://www.petri.co.il/install_windows_server_2003_ca.htm Then setup OWA with the certificates http://www.petri.co.il/configure_ssl_on_owa.htm Cheers Nathan

Hi, The first link above shows how to install a CA. It makes no difference whether you are going to use the certificates on a cluster or not. Cheers Nathan
