Common reasons IIS Server returns "HTTP 404 - File not found" error
View products that this article applies to.
Article ID : 248033
Last Review : October 5, 2005
Revision : 9.0
This article was previously published under Q248033
We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:
http://www.microsoft.com/technet/security/prodtech/IIS.mspx (

Important This article is written for Internet Information Services (IIS) administrators. If you are not an IIS administrator, but you want to understand what this error message means when you see it in your Web browser, click the following article number to view the article in the Microsoft Knowledge Base:
264284 (
http://support.microsoft.com/kb/264284/) What to do when you receive "The page cannot be found" error message in your browser
SYMPTOMS
When a Web page is requested, you receive the following error message at the top of the Web browser:
The page cannot be found
The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.
You receive the following error message further down on the Web page:
HTTP 404 - File not found
Internet Information Services
Back to the top Back to the top
CAUSE
The Web server returns the "HTTP 404 - File not found" error message when it cannot retrieve the page that was requested.
The following are some common causes of this error message:
The requested file has been renamed.
The requested file has been moved to another location and/or deleted.
The requested file is temporarily unavailable due to maintenance, upgrades, or other unknown causes.
The requested file does not exist.
IIS 6.0: The appropriate Web service extension or MIME type is not enabled.
A virtual directory is mapped to the root of a drive on another server.
Back to the top Back to the top
RESOLUTION
To resolve this problem, verify that the file requested in the browser's URL exists on the IIS computer and that it is in the correct location.
Use the IIS Microsoft Management Console (MMC) snap-in to determine where the file requested must exist in the IIS computer's file system.
This is particularly important if the Web site uses a virtual directory (VDIR). A VDIR is a directory that is not contained in the home directory of the Web site, but appears to client browser as though it does. This virtual directory must be mapped to a subfolder on a drive or reference the files by name.
For example, assume that the URL that caused the 404 error is
http://Microsoft.Com/Test/File1.htm, and the IIS snap-in shows that for Microsoft.Com Web site, the /Test/ directory is actually a virtual directory that maps to the location of c:\Information on the IIS computer. This means that you must verify that the File1.htm file is located in the c:\Information directory (and that the file name is spelled correctly).
IIS6 Dynamic Content: A 404.2 entry in the W3C Extended Log file is recorded when a Web Extension is not enabled. Use the IIS Microsoft Management Console (MMC) snap-in to enable the appropriate Web extension. Default Web Extensions include: ASP, ASP.net, Server-Side Includes, WebDAV publishing, FrontPage Server Extensions, Common Gateway Interface (CGI). Custom extensions must be added and explicitly enabled. See the IIS 6.0 Help File for more information.
IIS6 Static Content: A 404.3 entry in the W3C Extended Log file is recorded when an extension is not mapped to a known extention in the MIME Map property. Use the IIS Microsoft Management Console (MMC) snap-in to configure the appropriate extension in the MIME Map. See the IIS 6.0 Help file for more information.

HTTP Error 404 "Page cannot be displayed" when you attempt to connect to the OWA server after you upgrade from Exchange Server 5.5 to Exchange 2000 Server
View products that this article applies to.
Article ID : 288123
Last Review : April 25, 2005
Revision : 4.2
This article was previously published under Q288123
SYMPTOMS
After you upgrade Exchange Server 5.5 to Exchange 2000 Server, you cannot connect to the Exchange Server computer using Outlook Web Access (OWA). When you try to connect to the OWA server, you may receive an HTTP 404 "Page cannot be displayed" error message.
Also, when you start the Internet Services Manager, right-click Default Web Site, click Properties, and then click the ISAPI Filters tab, if two Exchfilt.dll files appear, you receive the "Page cannot be displayed" error message. However, no errors or warnings are logged in Windows NT Event Viewer, and any other virtual directories or Web pages that are stored on the default Web site load correctly.
NOTE: If you have installed Exchange 2000 Conference Server on this computer, you will see "Microsoft Exchange Conferencing Web Component" as the name of the ISAPI filter.
When the Exchange Server 5.5 version of the Exchfilt.dll file appears, the Exchange 2000 version of Exchfilt.dll does not load. Depending on your authentication method, you may also receive the following error message:
HTTP 404 "File not found."
If you view the IIS logs for the Web site, you see that the 404 error is returned after the HTTP GET request is redirected to the Exchange/USA/Username folder. The USA folder is only used in Exchange Server 5.5, and it does not exist in Exchange 2000.
NOTE: USA is a localization folder. The USA folder may be replaced with a different language folder if OWA is set up for multiple language support.
Back to the top Back to the top
CAUSE
This behavior can occur if Exchange 2000 Setup did not remove the existing Exchange Server 5.5 version of the Exchfilt.dll file from the list of ISAPI filters that are loaded by the default Web site. The old Exchange Server 5.5 Exchfilt.dll file automatically tries to redirect the user to the USA folder.
Back to the top Back to the top
RESOLUTION
To resolve this issue:
1. Click Start, point to Programs, click Administrative Tools, and then click Internet Services Manager.
2. Right-click Default Web Site, and then click Properties.
3. Click the ISAPI Filters tab.
4. Click exchfilt, and then click Remove.
5. Click Apply, and then click OK.
NOTE: Do not delete the Microsoft Exchange Web Component entry on the ISAPI filters tab. This filter is the Exchange 2000 OWA ISAPI filter component and must be present for OWA to work properly.
Back to the top Back to the top
MORE INFORMATION
To differentiate between the two versions of the Exchfilt.dll file, compare the location and the version stamps of each file. The Exchange Server 5.5 Exchfilt.dll file is located in %SystemRoot%\System32, by default. The Exchange 2000 Exchfilt.dll file is located in C:\Exchsrvr\Bin, by default. (For new installations, the files are located in C:\Program files\Exchsrvr\Bin, by default.) The version stamp of the files indicates which .dll is the correct version to use with Exchange 2000:
Version of Exchfilt.dll Exchange Version
5.5.1960.4 Microsoft Exchange Server 5.5
6.0.4417.0 Microsoft Exchange 2000 Server
6.0.4417.0 Microsoft Exchange 2000 Conferencing Server
