Hi All, I'm planning to procure Digital certificate for my E2K7 Servers. Two of the server acts as both CAS and HT and they will be internet facing; configured on NLB. I want to support webmail, outlook anywhere/autodiscover, Active Sync. I would buy a a UC certifcate with SAN for this. Does the host name of the CAS/HT servers be part of the SAN? I have a split DNS where the name of cas/ht are CASHT1.blr.contosl.com & CASHT2.blr.contosl.com but the SMTP or external namespace is contoso.com what all the domains name should i include in the Certificate? should it be just mail.contoso.com , autodiscover.contoso.com, activesync.contoso.com, webmail.contoso.com or mail.contoso.com , autodiscover.contoso.com, activesync.contoso.com, webmail.contoso.com, CASHT1.blr.contosl.com & CASHT2.blr.contosl.comswamy

You need: webmail.contoso.com autodiscover.contoso.com server1.contoso.com server2.contoso.com most of the services will use webmail.contoso.com (or mail, or email or whatever you decide to call it) Mike Crowley Check out My Blog!

Thanks Mike. my server names are CASHT1.blr.contosl.com & CASHT2.blr.contosl.com not server1.contoso.com & server2.contoso.com. does it mean mail.contoso.com (outlook anywhere) webmail.contoso.com (OWA) Activesync.contoso.com (Active Sync) autodiscover.contoso.com (autodiscover) CASHT1.blr.contoso.com CASHT2.blr.contoso.com Does the above looks good for the UC SAN certifiacate? As yo can see the host name in the internal network contains the blr.contoso.com no just contoso.com swamy

Hi swamy, You just need to include the following domain names: mail.contoso.com , autodiscover.contoso.com, activesync.contoso.com, webmail.contoso.comPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Gen, why are you recommending a seperate name for ActiveSync. I've never seen this done. You also differentiate between webmail and mail. This too seems unncessary based on the abovementioned design. Channavera, let me rephraase: webmail.contoso.com autodiscover.contoso.com Active Directory FQDN of server 2 Active Directory FQDN of server 2 Mike Crowley Check out My Blog!
