Use two different CAS Array FQDN's, one for each site. In DR, you would change the DNS record to point to the surviving site. Also be sure you set the database property RPCClientAccessServer depending on where the active database is.

Primary Site: Redundant CAS, HT, Mailbox servers Split DAG to replicate to DR site All users mailbox will be active at this site DR site: CAS, HT, Mailbox servers DAG copy of mailbox databases So I create a CAS array at each site, CASA-Primary and CASA-DR. What do I use for the FQDN for each CAS array? Can I use the same FQDN in each array, say Outlook.company.com, and the DNS entry would point the VIP for primary site and in the event of site failure I would update the DNS entry to point to the VIP at the DR site? How does this change if we decided to have active mailbox databases at each site, and to make it simple we keep on the 1 DAG? --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
