F.18 iFolder 2.1.3 on Windows 2003 Server FAQs

F.18.1 Why is the iFolder Administration page displaying error message such as “The application called an interface that was marshalled for a different thread”? What can I do to resolve this?

The reason for this could be that the IIS Web site is configured to run in the IIS 5.0 isolation mode with security level set to Medium.

To resolve this, set the Security level to Low.

F.18.2 Why is the iFolder Advanced Search failing with the error "Bad Request (Invalid URL)"?

The advanced search might be made on a context. Use the simple search page to search for the users.

F.18.3 The iFolder login is failing for a multi-home Web site. What can I do to resolve this?

To resolve this, use the IP address instead of DNS name for the following settings:

  • The iFolderServerDNSorIP and iFolderServerSecureDNSorIP attributes of the iFolder Server object

    To do this,

  1. In the iFolder Administration page, select the Global Settings > iFolder Servers.

  2. In the iFolder Servers page, select the Server for which the multi-home Web site login is failing.

  3. In the Host DNS or IP field of the selected server page, change the DNS name of the server to the IP address.

  • Connection information for the client login.
  • In the registry key located at
    My Computer\H KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC\iFolderServer

Change the following:

  • Replace the value of iFolderServerDNSorIP with the IP address of the iFolder Server.
  • Replace the value of ServerDNSorIP with IP address of the iFolder Server.

F.18.4 iFolder fails to work after renaming domain controller. What can I do to resolve this?

In the registry key located at 

My Computer\H KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC\iFolderServer

Change the following attribute values, if applicable, from old Domain Controller name to new/changed Domain controller name.

  • iFolderServerDNSorIP
  • LdapHost
  • ServerDNSorIP

Restart the IIS.
