Hello, I dont' exactly where to post this message so I apologize in advance for any mistake. I have a question about Windows 2003 Certificate Authority servcies : I would like to know how to provide high availability for this Windows service. Thanks in advance for your help !

*bump* nobody have an idea ?

Hi , Sorry for the delayed response For windows 2003 CA you should deploy multiple CA for providing high availability , but windows 2008 eliminates this by introducing HSM concept, you can read through more from the below link http://www.microsoft.com/downloads/details.aspx?FamilyID=15c75333-be26-4955-a32c-03077daf1631&DisplayLang=en Also you cannot perform CA clustering on windows 2003

Hi, thanks for your reply but my question concerns windows 2003 :-) (but thanks also for the details about win 2008 CA ! ) I'm sorry but I don't understand when you said "deploy multiple CA" .. I don't have heavy skill in this domain and I don't really know how technically deploy multiple CA. On my own knowledge, deploy multiple CA means deploy a ROOT and several CHILDS. But my application is directly linked to a unique CA (<CA_server_fqdn>\<CAname>), and then if I deploy several CA they cannot have the same name, and I'm stucked. Can you please give me more details ? Thanks in advance !
