Introduction

The Cisco Unity web server sporadically fails to display the web/SA login page. The web page simply fails to appear, even though the certificate acceptance box appears and asks whether to continue.

This document describes the workaround for this problem.

Prerequisites

Requirements

Cisco recommends that you have knowledge of Cisco Unity.

Components Used

The information in this document is based on the Cisco Unity 4.x and 5.x.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

Problem

The Cisco Unity SA web page is not accessible to the Cisco Unity Administrators.

If you restart the IIS, it clears the problem temporarily. This is seen occasionally with Cisco Unity servers that run on Microsoft Windows Server 2003, typically after an SA session times out. This problem is seen with Cisco Unity 4.2(1) and 5.0(1).

Solutions

In order to overcome this problem, review these options:

• Restart the WWWP service.

  or

• Increase the SA Session Timeout value in the Internet Information Services (IIS) Manager from the default of 20 minutes to 180 minutes, or more. Additionally, you can set the Idle Timeout to a value lower than the SA Session Timeout in order to workaround this issue.

  This does not prevent the problem, but it does decrease the chances of occurrence.

  These steps describe how to increase both the session and the idle timeout values, and to set the idle timeout to a value less than the session timeout.

  In order to increase the session timeout, complete these steps

  1. Choose Start > Programs > Administrative Tools > Internet Information Services (IIS) Manger.

  2. In the left-hand pane, expand the tree for the local computer.

  3. Right-click the Default Web Site, and select Properties.

  4. Click the Home Directory tab.

  5. Click the Configuration button.

  6. On the Application properties sheet, click the Option tab.

  7. Increase the session timeout from the default 20 minutes to the desired number (180 minutes or more).

  In order to change the idle timeout, complete these steps:

  1. In IIS Manager, expand the Application Pools folder.

  2. Right-click DefaultAppPool, and select Properties

  3. Select the Performance tab.

  4. Change the value in Idle timeout to a couple of minutes less than the session timeout for the SA.

  5. Click Apply.

  6. Restart the DefaultAppPool.

  Once these settings are changed, after the timeout fires, the browser window either closes on its own or a dialog box appears and asks if you want to close the window. A new SA session can be opened by the Cisco Unity icon in the System Tray.

  If you do not see the Application Pools container in IIS Manager, complete these steps in order to display the Application Pools and then adjust the idle timeout.

  1. Choose Start > All Programs > Administrative Tools > Internet Information Services (IIS) Manager in order to open IIS Manager.

  2. Expand the tree in the left pane.

  3. Right-click Web Sites and select Properties.

  4. Click the Service tab.

  5. In the Isolation Mode section at the top of the page, uncheck the Run WWW service in IIS 5.0 isolation mode check box.

  6. Click OK on the message box to restart IIS. The Application Pools container displays.

  7. Close IIS Manager.
