OCS 2007: Manually Configuring the External Web Farm FQDN

Original text from: http://technet.microsoft.com/en-us/library/bb803611.aspx

---------------------------------------------------------------------------------

If you did not configure an external Web farm FQDN when you created your Enterprise pool or configured your Standard Edition server, you can use some the following commands in LCSCmd to configure or change your external URLS specified in Table 3 Directories used by Web Components Servers (see the table in Step 2.1. Configure a Reverse Proxy).

To configure the external Web farm FQDN

1. Log on to the Standard Edition server or Enterprise Edition server in the pool with an account that is a member of RTCUniversalServerAdmins group or has equivalent permissions.

2. Open a command-line prompt.

3. Navigate to the \Program Files\Common Files\Microsoft Office Communications Server 2007 directory.

4. To set the external URL for the Web farm, type the following command:

   Lcscmd /web /action:updatepoolurls /externalwebfqdn: /poolname:

   For example:

   Lcscmd /web /action:updatepoolurls /externalwebfqdn:contoso.com /poolname:pool2

   Lcscmd /web /action: ListWMISettings /poolname:pool2
