Introduction

You can use log files from Microsoft Internet Information Server (IIS) when you troubleshoot issues with Cisco web-based products. This document describes where to find these log files.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

  • How to navigate in a Windows environment

Components Used

The information in this document is based on these software and hardware versions:

  • Cisco Collaboration Server version 5.0 and later

  • Cisco Media Blender version 5.0 and later

  • Cisco Trailhead Server version 4.0

  • Cisco Dynamic Content Adapter version 2.0.1

  • WebView for Cisco ICM version 4.6.2 and later

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

Refer to Cisco Technical Tips Conventions for more information on document conventions.

Identify the IIS Log File Location

By default, IIS log files reside in the c:\winnt\system32\LogFiles\W3SVC1 directory. These files have the naming convention ex*.log (see Figure 1). These files contain information on client requests against the web server.

Nondefault IIS Log File Location

Use the Internet Services Manager to determine the settings for logs within IIS. Here is the default program location, depending on the operating system version:

  • Windows 2000—Click Start > Settings > Control Panel > Administrative Tools > Internet Services Manager.

  • Windows NT 4.0Start > Programs > Windows NT 4.0 Option Pack > Microsoft Internet Information Server > Internet Service Manager.

When you select the Internet Service Manager option, the Internet Services Manager window opens.

Complete these steps:

  1. Double-click Internet Information Services to view the list of associated servers.

  2. Double-click the server name to view the list of sites on the server.

  3. Right-click the site name in use (usually "Default Web Site") and choose Properties.

  4. Click Properties in the "Enable Logging" section at the bottom of the dialog box.

    Figure 2 – The Log File Directory Field

    You can now see a field called Log file directory, which lists the directory that is currently set for logging.

Gather Log Files

After you determine the location of the log files, navigate to that directory in order to review the log files. You can use a standard text editor to read the files. If you want to retrieve logs related to a Cisco TAC case, ensure that you gather all logs that cover the time before and during the issue.
