WebView II is a browser-based software program that is used to view
reports from a server. Reports can show real-time or historical system data.
This document describes how to troubleshoot the error message,
"HTTP 500: Internal Server Error", when you
launch WebView reports.
Cisco recommends that you have knowledge of these topics:
Cisco Intelligent Contact Management (ICM)
Microsoft Windows NT/2000 Security
Microsoft Internet Information Server
The information in this document is based on these software and
Cisco ICM versions 4.5.x and 4.6.x
Microsoft Windows NT and Windows 2000
Microsoft IIS 4.0 and 5.0
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.

In the WebView II reporting menu, when you click on any report category
in the left pane of the browser, you should receive a list of available reports
for the selected category. Instead, "The page cannot be
displayed" and “HTTP 500 - Internal Server
Error” error messages appear, as shown in
Figure 1: WebView Error Message
This symptom might not appear for all WebView II users.
WebView II uses the NewAtlanta ServletExec Servlet plugin for IIS to
generate a list of available items for a specific report. ServletExec ISAPI
folder is usually located in the c:\Program Files\New
If certain users and groups have not been granted sufficient Microsoft
Windows NT File System (NTFS) security permissions, retrieving report items
fails, most likely with the HTTP error 500. If you use the NTFS, permissions
for the ServletExec ISAPI directory and its subdirectories, they must have read
and write access to these directories. Because ServletExec/ISAPI runs as part
of the IIS process, it runs as a different user at different times.
These groups need to be granted Full Control
permission to the ServletExec ISAPI directory and its subdirectories:
This user needs to be granted Full Control to the
ServletExec ISAPI directory and its subdirectories:
After you install MS patches on all ICM systems, the WebView no longer
works and returns this error:
HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials.
This issue might occur if the IUSR account for IIS authentication is
assigned as a member of the Guests local group instead of Users. In order to
resolve this issue, change the group membership of IUSR account from the
GUESTS group, and add it to the USERS
