I have never used a Stretched VLAN but I will take a look at it. Thanks. From: Al Rose [mailto:[email protected]] Sent: Friday, June 10, 2011 3:21 AM To: MS-Exchange Admin Issues Subject: Re: Multiple sites 2003 to 2010 deployment
have you considered stretched VLAN and CAS Array? On Thu, Jun 9, 2011 at 6:38 PM, Jiri P. Kukol <[email protected]<mailto:[email protected]>> wrote: Right now we have two 2003 servers (one per site) in one domain, both setup with a MX record in external DNS. If one server fails, most incoming messages get automatically redirected to the other one and both servers send outgoing messages directly. External users can connect to the server that stores their data using either server1.domain.com/Exchange<http://server1.domain.com/Exchange> or server2.domain.com/Exchange<http://server2.domain.com/Exchange> (they know which one to use). What's the best way to replicate the setup with 2010? I would like to keep two MX DNS records (in case one site goes down) and run two CAS servers (one per site). It is kind of working - I have moved all users in one site to the new 2010 server and they have no problems (internally they can connect using Outlook, externally they can connect using server1.domain.com/owa<http://server1.domain.com/owa> and autodiscover allows them to easily connect using mobile devices). Now I would like to start using the second server for users in the second site but I ran into at least one problem - the Autodiscover service. The external DNS (autodiscover.domain.com<http://autodiscover.domain.com>) points to the first server and I am not sure how to setup the second one in the second site. This is causing problems for both users and some other services (VIPRE for Exchange requires the autodiscover to work). Any suggestions? Or is there a better way to set it up? I searched for a similar scenario with two CAS servers in two sites in the same domain (both the archives and the Internet) and I did not find much. Thanks.
