By default, forms-based authentication is not enabled for Outlook Web Access in Exchange2007. Forms-based authentication stores the user’s user name and password in a cookie instead of in the browser. When the user leaves an OWA session or after the expiration of the inactivity period, the cookie is cleared. As a result, the user must re-authenticate to use OWA again. This is a good security measure.To enable the Outlook Web Access logon page, do the following:
1. Open the Exchange Management Console.
2. Choose Server Configuration > Client Access.
3. Click the “Owa (Default Web Site)” entry.
4. From the Action pane, choose the Properties option.
5. From the Owa (Default Web Site) Properties page, click the Authentication tab.
Under the “Use Forms-Based Authentication” option there are three options for enforcing a particular logon format. The Domain\User Name option is self-explanatory and is useful if you have multiple domains. The User Principal Name (UPN) option, or e-mail address format, is probably the easiest for users to remember since they use it all the time. The User Name Only option is the last option, which is also self explanatory. If you choose the User Name Only format, you also need to choose a Logon Domain.
6. Click OK
Because this change affects IIS, you must restart IIS. From a command line on the Outlook Web Access server, issue the command iisreset /noforce.

High Availability uses a combination of redundancy and fault tolerance in order to provide a level of operational continuity.Redundancy means that there is more than one instance of resources available. Fault Tolerance means that resources will be available even if there is a hardware failure.
Configuring round robin
Round robin is a local balancing mechanism used by DNS servers to share and distribute network resource loads. You can use it to rotate all resource record (RR) types contained in a query answer if multiple RRs are found.
By default, DNS uses round robin to rotate the order of RR data returned in query answers where multiple RRs of the same type exist for a queried DNS domain name. This feature provides a simple method for load balancing client use of Web servers and other frequently queried multihomed computers.
If round robin is disabled for a DNS server, the order of the response for these queries is based on a static ordering of RRs in the answer list as they are stored in the zone (either its zone file or Active Directory).
Example: Round-robin rotation
A forward lookup-type query (for all A RRs that match a DNS domain name) is made for a multihomed computer (multihomed.example.offsitenoc.com) that has three IP addresses. Separate A RRs are used to map the host’s name to each of these IP addresses in the zone. In the stored example.offsitenoc.com zone, the RRs appear in this fixed order:
multihomed IN A 192.168.1.1
multihomed IN A 192.168.1.2
multihomed IN A 192.168.1.3
The first DNS client that queries the server to resolve this host’s name receives the list in default order. When a second client sends a subsequent query to resolve this name, the list is rotated as follows:
