Problem loading the IIS plug-in
 Technote (troubleshooting)
 
Problem(Abstract)
Plug-in will not load when trying to configure the IBM WebSphere Application Server plug-in module in Microsoft Internet Information Services (IIS) V5.0 (all releases) and V6.0 (all releases).
 
Cause
Two different ISAPI filters are loading the same module.


Problem details

See the information center articles Configuring the plug-in for Microsoft Internet Information Services 6.0 on Windows 2003 server and Manually configuring supported Web servers.

After following the preceding documents and trying to load the plug-in, the ISAPI filter will have a red arrow and will not load. This is due to two ISAPI filters, sePlugin and iisWASplugin, loading the same plug-in module and plug-in file.

Notice that when you right-click on the Web Sites folder, there is a tab called ISAPI Filters. When you look at this tab, it indicates the status of sePlugins is Loaded (represented by a green up arrow):



However, when you look at the IIS plug-in filter, the plug-in is not loaded:


 
Resolving the problem
  1. Backup the plug-in module (iisWASPlugin_http.dll) and the plug-in file (plugin-cfg.xml), as deleting the ISAPI filters will remove the modules associated with it.

  2. Remove the sePlugin ISAPI filter, but make sure you deselect the registry entry for the plug-in when you remove the sePlugin filter. Also remove the iisWASPlugin filter.

  3. Put the plug-in module (iisWASplugin) back to where it belongs (install_root/AppServer/bin). You can also run the custom install of the plug-in if you do not want to backup and copy the module.

  4. Follow the instructions to configure the plug-in for IIS and configure ISAPI filter for WebSphere plug-in. This time it should load the plug-in module.
