The error "HTTP Error 404 - File or directory not found" appears in the browser when attempting to access http://yourhost/mewebmail or http://yourhost/meadmin (even though web mail or web administration support has been configured for that web site).
This issue may occur if ASP.NET has not been installed/configured on the server. MailEnable .NET web applications (i.e. web administration and web mail) require that ASP.NET is installed on the server.
ASP.NET needs to be installed on the server so that IIS understands how to process ASPX web pages. In some situations, it is possible that the .NET Framework is installed, however ASP.NET (Script Mappings for processing ASPX pages) may not have been configured.
To resolve the issue, it is necessary to install/configure ASP.NET for IIS on the server. There are two configuration changes that need to be made to IIS.
Enable the Web Service Extension (IIS Version 6 and later)
If using IIS 6 or later (i.e. Windows 2003 or later) access the Internet Service Manage (IIS Management Console) and check that the ASP.NET and ASP Web Service Extensions are allowed). If these were subsequently enabled, then test whether web mail and/or web admin function.
Configure ASP.NET Script Maps
If problems are still being experienced, it may be that the ASP.NET script maps have not been configured under IIS. A procedure for enabling them is outlined below:
1. Select Start, and then select Run.
2. In the Open text box, type cmd, and then press ENTER.
3. At the command prompt, type the following, and then press ENTER:
In this path, version represents the version number of the .NET Framework that is installed on the server. This placeholder must be replaced with the actual version number when typing the command.
