To create a host record for a Communications Web Access server

1. Log on to the DNS Server as a member of the Domain Administrators group.
   
   
2. In the DNS snap-in, expand the name of the DNS server, expand Forward Lookup Zones, right-click the name of your domain, and then click New Host (A or AAAA).
   
   
3. In the New Hostdialog box enter the host name of the Communicator Web Access Web site (for example, cwa) in the Namebox; make sure that the URL for that site (for example, cwa.litwareinc.com) appears in the Fully qualified domain namebox.
   
   
4. Type the IP address for the server in the IP addressbox and then click Add Host.
