Hello,I wanted to implement front end server in my company. Main purpose is to consolidate all sites owa through a front end .For this iam implementing in a lab setup first for my manager to approve it.What i have done:1) Forest Ad domain : ccofc.edu2) Child AD domains: cccs.ccofc.edu and acc.ccofc.edu in two microsft virtual servers.First exch 2k3 server installed on cccs domain.( housing mailboxes) --smtp domain created as @LowryCollege.eduFQDN of exch server -- >cccsdena11.cccs.ccofc.edusecond exch 2k3 server on acc domain ( housing mailboxes) -----------smtp domain created as @Arapahoe.eduFQDN of exchange server---> acc.ccofc.eduI can send mail by OWA . I created a DNS domain, as Lowrycollege.edu with MX record pointing to cccsdena11Now i type http://mail.lowrycollege.edu/exchange and works fine.NOW I am trying to implement FE.I installed third exch 2k3 server in the physical machine and joined to the administrative group containing first exch server( that is lowrycollege) and made it a front end.restarted server.Read http://www.microsoft.com/technet/prodtechnol/exchange/2000/maintain/e2kfront.mspxhttp://hellomate.typepad.com/exchange/2003/07/owa_and_multipl.htmland sone others too.Created a virtual srvr in front end . Name :LowryCollege, selected "Mailboxes for SMTP Domain" and typed Lowrycollege.edu as the SMTP domain.Hostheader given as "cccsdena11.cccs.ccofc.edu" .Also created a virtual directory under this server with the name "Exchange" and selected "Mailboxes for SMTP domain"and typed "Lowrycollege.edu". Also restarted the virtual server.Created the same thing in cccsdena11 ( which is the backend server for smtp domain lowrycollege.edu)Now when i type:http://lowrycollege.edu/exchange or http://lowrycollege.edu it does not come up. But when i right click the virtual server and say "browse" it will ask for authentication.Read in the above article that host header is the name that u want to type in the browser. so changed hostheader from cccsdena11.cccs.ccofc.edu to www.lowrycollege.edu and it will not work( any ways this setting will not work because if i right click the virtual server and say browse it will not)The article does not discuss abt the creation part neat. Also i could not find a better doc in the internet.Any help greatly appreciated !.PS: i deleted the domain RUS in the root AD domain (ccofc) as it will not allow me to select it as a front end srvr.But anyways i dont have any mailboxes/Pfolders on the front end)ThanksRaj07
