Form Error on installing CRM 2011


If you see this error message, you have a problem with customization.

CRM uses a component called "Microsoft URL Rewrite 1.1 for IIS7" along with a rule that is visible within the CRM Web site configurations under the URL Rewrite section called “WebResourcesRule”.

There are instances in which the Microsoft URL Rewrite Module does not get loaded properly and/or the rewrite rules are missing.

On the CRM server you can open IIS Manager and choose the CRM website, and then you could begin by selecting Modules under IIS heading and making sure that Rewrite Module is in the list as shown below: %SystemRoot%System32Inetsrvrewrite.dll

Then select URL Rewrite under the IIS heading and verify that ClientGlobalContectRule, WebResourcesRule, FederationMetadataRule exist here.

If one or both of the above does not appear correctly, you have two solutions:

  1. Verify that Kernel-mode authentication is enabled

    • Launch IIS Manager on the CRM server, select CRM website, then select Authentication under the IIS heading, click on Advanced Settings and verify that “Enable Kernel-mode authentication” is marked.
  2. Repair or Reinstall the URL Rewrite Module

    • The installation can be located inside the CRM server installation media in a folder called UrlRewriteModule. The file name is rewrite_1.1_amd64_rtw. After reinstalling the module Reboot the CRM Server.

You can download Microsoft URL Rewrite Module 1.1 for IIS 7 (x64) from:
