When working with Forefront Unified Access Gateway (UAG) in an array that uses Network Load Balancing (NLB), you must take care when installing Update 1. This topic describes how to install Update 1 on a Forefront UAG array that is using NLB.

To install Update 1 on an array using NLB

  1. On the array manager server, in the Forefront UAG Management console, on the Admin menu, click Web Monitor.

  2. In Web Monitor, under Array Monitor, click Current Status.

  3. In the Array Monitor, under Nodes, select the check box for the array manager. Then, in the drop-down list, click Drain Stop, and click Apply.

    Note:
    For a Forefront UAG DirectAccess-only deployment, in the drop-down list click Stop, click Apply, and then continue with step 6.

  4. Wait until all sessions have finished.

    To check the number of sessions, in Web Monitor, under Session Monitor, click Current Status.

  5. In the Array Monitor, under Nodes, select the check box for the array manager. Then, in the drop-down list, click Suspend, and click Apply.

  6. Exit the Forefront UAG Management console.

  7. As the administrator, install Update 1 on the array manager by double-clicking the ForefrontUAG_KB981323_ENU.msp file.

    Important:
    If User Account Control (UAC) is turned on, to install Update 1, from an elevated command prompt, locate the folder containing the ForefrontUAG_KB981323_ENU.msp file, type ForefrontUAG_KB981323_ENU.msp, and then press ENTER.

    Restart the server, if required.

  8. Start the Forefront UAG Management console and activate the configuration.

    Note:
    For trunks that are configured with a certificate, on the main property page of the trunk, in Trunk Configuration, click Configure. On the Advanced Trunk Configuration dialog box, on the General tab, in the Server Certificate area, in the Server certificate drop-down list, select a different certificate. Then, on the Advanced Trunk Configuration dialog box, click OK. Reopen the Advanced Trunk Configuration dialog box, select the original certificate, and then click OK.

  9. Wait until the activation completes successfully on the array manager. Use the Activation Monitor to view the activation progress.

    Note:
    Activation will be successful only on the array manager. Do not wait for activation to succeed on the array members.

  10. On an array member (not on the array manager), in Web Monitor, under Array Monitor, click Current Status.

  11. In the Array Monitor, under Nodes, select the check box for the array manager, in the drop-down list click Resume, and then click Apply. When the NLB status changes to Stopped, in the drop-down list click Start, and then click Apply.

    Note:
    For a Forefront UAG DirectAccess-only deployment, in the drop-down list, do not click Resume; instead click Start, and then click Apply.

  12. Check that the activation was successful by browsing to the portal home page from a client endpoint.

  13. For each array member, do the following:

    1. On the array member, in the Array Monitor, under Nodes, select the check box for the array member. Then, in the drop-down list, click Drain Stop, and then click Apply.

      Note:
      For a Forefront UAG DirectAccess-only deployment, in the drop-down list click Stop, click Apply, and then continue with step d.
    2. Wait until all sessions have finished on the member that you stopped.

      To check the number of sessions, in Web Monitor, under Session Monitor, click Current Status.

    3. On the array member, in the Array Monitor, under Nodes, select the check box for the array member. Then, in the drop-down list click Suspend, and click Apply.

    4. As the administrator, install Update 1 on the array member by double-clicking the ForefrontUAG_KB981323_ENU.msp file.

      Important:
      If UAC is turned on, to install Update 1, from an elevated command prompt, locate the folder containing the ForefrontUAG_KB981323_ENU.msp file, type ForefrontUAG_KB981323_ENU.msp, and then press ENTER.
      Restart the server, if required.

    5. On the array manager server, activate the configuration.

    6. Wait until the activation completes successfully on the array manager and on the upgraded array member. Use the Activation Monitor to view the activation progress.

    7. On the array member, in Web Monitor, under Array Monitor, click Current Status.

    8. In the Array Monitor, under Nodes, select the check box for the upgraded array member. Then, in the drop-down list click Resume, and click Apply.
