Creating Certificate Requests in Windows that have multiple CNs
I am having an issue finding a way to get a certificate with multiple names on it issued so that I no longer have certificate not correct issues with my IIS sites. I am sure that this is simple and I am just leaving out a step or something, but I am just not able to find something that works by searching online so I thought I would ask. I want to generate a certificate that is good for both of these names: LANSrvr0 LANSrvr0.mynetwork.com Pretty basic stuff, I know, but I cannot seem to get the Certificates MMC and my internal Windows Server 2008 R2 ADCS server to give me a certificate with both on there. I am currently using a computer template for this, but maybe I need to use a different template? I dont know and would love it if someone had some guidance on this issue.

Hello, the Security forum is the better one to ask about CA and certificates http://social.technet.microsoft.com/Forums/en/winserversecurity/threadsBest regards Meinolf Weber MVP, MCP, MCTS Microsoft MVP - Directory Services My Blog: http://msmvps.com/blogs/mweber/ Disclaimer: This posting is provided AS IS with no warranties or guarantees and confers no rights.

Hi, I think you want to request a certificate with a custom Subject Alternative Name (SAN). The use of SANs in server authentication certificates enables a single certificate to be bound to multiple names on a single computer. For example, a web server might be identified by multiple DNS names. Also, multiple computer computers might host a website and each computer can request a certificate with the sites DNS name in the SAN. For soma combinations of client computer operation system and CA, two different procedures can be used: on procedure using the command-line application Certrey.exe and another procedure using either the Certificate Enrollment wizard or the CA Web enrollment pages. For more information please refer to following MS articles: How to Request a Certificate With a Custom Subject Alternative Name http://technet.microsoft.com/en-us/library/ff625722(v=WS.10).aspx Creating Subject Alternative Name Certificates with Microsoft Certificate Server http://blogs.technet.com/b/industry_insiders/archive/2007/03/23/creating-subject-alternative-name-certificates-with-microsoft-certificate-server.aspx Configure SSL Certificates to Use Multiple Client Access Server Host Names http://technet.microsoft.com/en-us/library/aa995942.aspxLawrence TechNet Community Support
