Bug: Microsoft Sharepoint does not start after installing ArcGIS Server .NET ADF is installed

Description

Microsoft's Sharepoint does not start when ArcGIS Server .NET Application Development Framework (ADF) is installed on the same machine. This occurs with ArcGIS Server .NET ADF versions 9.0 and 9.1.

Cause

This is caused by the setup of an ASP.NET HTTP Handler for streaming images from ArcGIS Server.

Workaround

  1. Open the machine.config file in a text editor. The machine.config file is typically found at the following location:
    C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\CONFIG\machine.config
  2. Find the following line which establishes the HTTP Handler for ArcGIS Server image streaming:

    Code:
    <add verb="*" path="ESRI.Web.Controls.MIMEImage.aspx"
    type="ESRI.ArcGIS.Server.WebControls.ImageHandler,
    ESRI.ArcGIS.Server.WebControls, Version=9.0.0.4, Culture=neutral, PublicKeyToken=8fc3cc631e44ad86"/>

  3. Add the validate attribute to that tag and set the attribute to false.

    Code:
    <add verb="*" path="ESRI.Web.Controls.MIMEImage.aspx"
    type="ESRI.ArcGIS.Server.WebControls.ImageHandler,
    ESRI.ArcGIS.Server.WebControls, Version=9.1.0.722, Culture=neutral, PublicKeyToken=8fc3cc631e44ad86" validate="false" />

    Sharepoint should now work correctly.
