Creating Communicator Web Access DNS Records

Topic Last Modified: 2009-01-25

The following procedures explain the steps involved in creating host name and CNAME records for the first scenario, the one where your Communicator Web Access (2007 R2 release) URL and your computers’ fully qualified domain name (FQDN) are the same. A similar approach can be used to create the required Domain Name System (DNS) records for other Communicator Web Access scenarios.

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 Host dialog box enter the host name of the Communicator Web Access Web site (for example, im) in the Name box; make sure that the URL for that site (for example, im.contoso.com) appears in the Fully qualified domain name box.

  4. Type the IP address for the server in the IP address box and then click Add Host.

To create canonical name records 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 Alias (CNAME).

  3. In the New Resource Record dialog box enter the first “alias” for the Communicator Web Access server. This first alias is as. followed by the fully qualified domain name (FQDN) of the server. For example, if your Communicator Web Access server has the FQDN im.contoso.com then the alias would be as.im.contoso.com.

  4. Make sure that the fully qualified domain name (FQDN) for the alias (for example, as.im.contoso.com) has been entered into the Fully qualified domain name box.

  5. In the Fully qualified domain name (FQDN) for target host box type the FQDN for the server itself (for example, im.contoso.com), and then click OK.

  6. Right-click the name of your domain a second time and then click New Alias (CNAME).

  7. In the New Resource Record dialog box, type the next alias for the Communicator Web Access server. The second alias is download. followed by the FQDN of the server. For example, if your Communicator Web Access server has the FQDN im.contoso.com then the alias would be download.im.contoso.com.

  8. Make sure that the fully qualified domain name (FQDN) for the alias (for example, download.im.contoso.com) has been entered into the Fully qualified domain name box.

  9. In the Fully qualified domain name (FQDN) for target host box type the FQDN for the server itself (for example, im.contoso.com), and then click OK.
