Resolution

• Make sure the correct URL is being used - for example:
  http:// /MetastormSSO/esso.asp?service=
  OR
  http:// /e-WorkSSO/esso.asp?service=.

• Open Internet Information Services (IIS) Manager. Go to the MetastormSSO (e-WorkSSO) virtual folder. The default location is \\Default Web Site\\MetastormSSO (e-WorkSSO). Right-click and select properties. On the Virtual Directory tab, make sure the Application name field is enabled and set to MetastormSSO (e-WorkSSO) (if that is the name of the virtual directory). If the Application name field is disabled, click the Create button and accept the defaults. Restart IIS.

• Verify that all of the steps in the Windows Single Sign On document have been followed exactly as specified.

• This issue has also been observed if the domain name contains an ampersand (&). For more information, see the Microsoft article Naming conventions in Active Directory for computers, domains, sites, and OUs
