How-To: Configure Windows 2003 for Web Components


Product: All

Version & Build: All


To run the Modus Web components on a Windows Server 2003, you must have the following configuration:

1. Ensure that you have .NET framework version 1.1 installed on the server

NOTE: .NET version 1.0 is no longer compatible with our code.  If you have both versions 1.0 and 1.1 installed on the server and are getting ASP.NET errors with our web applications, see the Troubleshooting section below.

If you have version 1.0 installed, it is recommended to uninstall it prior to installing 1.1 in order to avoid problems.


2. Verify that the ASP.NET component is activated on the server

  • Go to Control Panel > Add/Remove Programs > Add/Remove Windows Components > Application Server
  • Click on Details and select ASP.NET (if not checked)
  • Click OK and Next to install the component


3. Verify that Active Server Pages and ASP.NET are "allowed" in IIS

  • Right-click MyComputer > Manage > Services and Applications > Internet Information Services
  • Expand the directory tree and select Web Service Extensions
  • Make sure that Active Server Pages and ASP.NET are set to Allowed


4. Verify the properties of WebMail/WebQuarantine, WebMonitor and WebAdmin directories in IIS

  • In IIS, open the properties of Virtual Directory or Home Directory > Configuration > Options
  • Make sure that Enable Parent Paths is checked
  • Go to the Directory Security > Anonymous Access & Authentication control > Edit and make sure that Integrated Windows Authentication is checked


5. Permissions

Modify permissions must be given to the local machine's IUSR and Network Service accounts on:

  • The root Web folder, e.g., C:\Program Files\Vircom\Web


  • The individual WebMail / WebQuarantine and WebAdmin folders, e.g. ModusMail: C:\Program Files\Vircom\Web\Webmail and ...\Web\WebAdmin; ModusGate: C:\Program Files\Vircom\Web\Quarantine and ...\Web\WebAdmin.

Also add Read & Execute, List Folder Contents, and Read permissions to the root ModusMail or ModusGate directory for the IUSR and Network Service accounts, e.g. C:\Program Files\Vircom\ModusMail or ModusGate.

IMPORTANT: Be sure to propagate all above-listed changes to the child files & folders

NOTE: If using an Access database for mailbox authentication, give IUSR and Network Service accounts Modify permissions on the .mdb file



If the web components had been installed prior to installing or upgrading to .NET framework 1.1, run the following command from a DOS prompt: aspnet_regiis -I.  This will try to bind all aspx code to the new .NET framework.

If this step does not work:

  • Uninstall both .NET framework versions (1.0 and 1.1)
  • Reinstall .NET 1.1 and reboot
  • Reinstall the Modus Web components (no need to install the mail portion)
If none of the above steps work, contact Support at or 514-845-8474.
