Cannot push the password recovery website to a remote system

Problem

Enterprise / Random Password Manager cannot push the password recovery website or the “check system compatibility” fails when attempting to push the website to a remote system.

Cause

Possible causes include:

  • A firewall being enabled and blocking file sharing and/or DCOM communication (dllhost.exe, port 135)
  • File and printer sharing not being installed/enabled
  • Internet Information Services (IIS) not being installed locally. IIS is required locally in order for Enterprise / Random Password Manager to recognize the COM interfaces required to perform a remote push of the website.
  • Application Server server role is not installed
  • COM versions are incompatible


Resolution

Firewall blocking file and printer sharing and/or DCOM communication

Most software firewalls will block all incoming traffic unless otherwise configured. Either turn off your firewall during the installation process or allow communication from the machine running Random Password Manager for file and print sharing (ports 137,138,139 and/or 445) and for DCOM communication (dllhost.exe, port 135).

You may also perform a manual installation of the website as outlined in the help manual of Random Password Manager.

File and printer sharing not being installed/enabled

If “File and Printer Sharing for Microsoft Networks” is not listed, you will need to install it to perform an automated push of the web site. If you do not wish to install “File and Printer Sharing for Microsoft Networks” you will need to perform a manual installation of the website as outlined in the help manual of Random Password Manager.

Installing “File and Printer Sharing for Microsoft Networks” will also install and start the SERVER service which is required for remote connectivity.
  1. Open your network connection’s properties:
    • In Windows 2000, right click on “My Network Places” and select properties.
    • In Windows XP/2003, open Control Panel and open “Network Connections”.
    • In Windows Vista/Server 2008, open Control Panel and open “Network and Sharing Center”, then select the link in the top left to “Manage network connections”.
  2. Right-click on your network connection and choose properties
  3. If “File and Printer Sharing for Microsoft Networks” is listed, ensure that it is enabled by placing a checkbox next to it.
  4. If “File and Printer Sharing for Microsoft Networks” is not listed, you will need to install it to perform an automated push of the web site.
  5. To install “File and Printer Sharing for Microsoft Networks” click the INSTALL button.
  6. Select “Service” and click ADD
  7. Click OK to close your network connection properties.

Internet Information Services (IIS) not being installed locally.

IIS is required locally in order for Enterprise / Random Password Manager to recognize the COM interfaces required to perform a remote push of the website. You do not need a complete installation of IIS on the local computer to push the password recovery website to a remote system; a bare installation of World Wide Web Services is sufficient.

If you do not wish to install “Internet Information services” on your local machine, you will need to perform a manual installation of the website on the remote system as outlined in the help manual of Random Password Manager.
  1. Open your network connection’s properties:
    • In Windows 2000/XP/2003, open Control Panel and open “Add/Remove Programs” the select “Add/Remove Windows Components”.
    • In Windows Vista/2008, open Control Panel and open “Programs and Features”, then select the link in the top left to “Turn Windows features on or off”.
  2. Choose to install World Wide Web Services:
    • In Windows 2000, choose “Internet Information Services” and then click DETAILS.
    • In Windows XP/2003, select and enable “Application Server” so that the check box is gray with a check mark.
    • In Windows Vista select “Internet Information Services”.
    • In Windows 2008 Server Manager, select ROLES from the left pane, then select “Add Roles” from the right pane. Select “Web Server” from the available roles then click NEXT.
  3. Choose the necessary sub-components:
    • In Windows 2000 you only need to enable “World Wide Web Server” and “Internet Information Services Snap-In”
    • In Windows XP/2003, following step 2 will enable only the requirements for IIS.
    • In Windows Vista/2008 select “Internet Information Services”. Then expand “Web Management Tools” and select all items under “IIS 6 Management Compatibility”. Windows will prompt you if it requires additional components.
  4. Click OK to accept your choices.
  5. Click NEXT to install Internet Information Services.


Application Server server role is not installed

In Windows 2008 and later, remote COM access is not provided for the target web server unless the Application Server server role is installed. Add the application server role and add the sub-component for Network COM+ Access.

COM versions are Incompatible

COM+ interfaces can only communicate to the same version of COM+ or older. Windows NT4 has version 1.0, Windows 2000 has version 1.5, and XP and later have version 2.0. Thus pushing the website from a machine running Windows 2000 to a Windows 2003 system will result in an error message that states that the COM interfaces are not supported.

Applies To:

Random Password Manager (RPM)
Enterprise Random Password Manager (ERPM)
