Failover problem

[NortonES2]

Hi I have installed the RTM version on 2 servers in different sites and have configured the DAG and database copies successfully. I can mount the database on both servers and when I shut the primary exchange server down the database is mounted automatically on the 2nd server, so far so good. However Outlook 2007 does not connect to the 2nd server and therefore connect to the mailbox, what part of the jigsaw am I missing?

I have never used Exchange 2007 so the clustering aspect is still new to me, we will be moving straight to 2010 from 2003 once our test environment has proved successful.

Thanks for any ideas you may have.

2010 doesn't really use clustering per-se, with the exception of the heartbeat stuff.

What do the logs say?

I have not deployed Exchnage 2010 as of yet, but it was my understanding that you would need a hardware load balancer for doing DAG. I'm assuming that doing this with Exchange is the same or close to it as doing OCS with servers in a pool, so you'd have to create the nessessary DNS records to the VIP (virtual IP) of the hardware load balancer which your clients would then point to so failover would happen.

Let me know if I'm wrong about that Pat since, again, I'm talking from a OSC perspective and have not done this yet with Exchange.

A hardware load balancer is only needed if you have two (or more) servers that are in a DAG -AND- those servers also have the CAS and HT roles. The load balancer is only for the CAS and HT roles, not the DAG.

The load balancer is what I'm missing as it is the CAS role that outlook connects to.

Though would still be stuck if the load balancer was in the site that failed. Trying to allow for the London office being destoyed and getting the DR site up and running.

Seem to have resolved it, I had the CAS and HT roles installed on both servers but I hadn't created a CAS Array, once this was done I could alter the DNS and Outlook could connect to the CAS instance in the second site

Thanks for help
