"The Page Cannot Be Displayed"
1. When troubleshooting Internet Explorer 6.0 problems, it is suggested that third-party Tool Bands and Browser Helper Objects features which have been installed be disabled, [Q298931].
a. Tool Bands supports the Radio Toolbar and can place a window on a band contained by the Rebar control that holds the toolbars.
b. Browser Helper Objects are Component Object Model (COM) components which loads whenever IE starts. These objects run in the same memory context as the browser and they can perform any action on the available windows and modules.
c. Supplemental reading:
(1) "Browser Helper Objects: The Browser the Way You Want It?
(2) "What is a Browser Helper Object?."
(3) "BHODemon" that can be downloaded may assist with your situation perhaps.
2. If you browse the Internet with 64-bit Internet Explorer 6.0 on a 64-bit Microsoft Windows XP-based computer and you view a Web page that contains a 32-bit ActiveX control, you are prompted to install the ActiveX control. When you attempt to install the ActiveX control, the installation process is unsuccessful. Although the activeX control acts like it is being installed, it is not, [Q294517].
3. Browser extensions allow developers to provide easy access to their browser enhancements by adding elements like an Explorer Bar to the default user interface. Introduced in Internet Explorer 4.0, this feature enables developers to create Explorer Bars and add entries into the standard context menus. Beginning with Internet Explorer 5, this feature allows developers to add entries into the Tools menu and buttons besides a host of many other things. Close all instances of Internet Explorer before starting!
a. Click Start, Control Panel, Network and Internet Connections, Internet Options, Advanced tab.
b. Under Browsing, clear the Enable third-party browser extensions (requires restart before it takes affect) check box, and then click OK.
4. The article [Q328785] explains that when you use IE to connect to a File Transfer Protocol (FTP) site that requires authentication, you may not be able to connect to the site because:
a. When you connect to an FTP site, IE first sends anonymous credentials to see if a connection can be established. In most cases, IE can connect using anonymous credentials. However, if the FTP site requires credentials, IE prompts you for credentials again because the anonymous credentials that are sent are not successful.
b. However, if the Show friendly HTTP error messages option on the Advanced tab of Internet Options is turned on, IE does not generate an Authentication dialog box for you to enter the correct user name and password. Because you are not prompted to reauthenticate to the FTP site, you cannot connect to the site and you receive the error message:
The page cannot be displayed
5. The TechNet article explains the "Internet Explorer Add-on Management and Crash Detection" that allows users to view and control the list of add-ons; it attempts to detect crashes in Internet Explorer that are related to an add-on; users are able to view, enable, and disable the add-ons used by Internet Explorer and identify add-ons that might be related to Internet Explorer crashes to improve the overall stability of Internet Explorer.
6. Connection and page problems can be caused by any of the following circumstances (and probably a lot of others), [Q812336]:
a. Internet Explorer connection settings are incorrect, "How to Troubleshoot Possible Causes of Internet Connection Problems (Q314095)."
b. An incorrect entry exists in a "Hosts" file, [Q309642].
Note: The "Hosts" file is used for host name resolution and found in c:\winnt\system32\drivers\etc\ for Windows NT/2000/XP Pro, or c:\windows\system32\drivers\etc\ for XP Home. To open the file using Notepad, start Notepad, and then use a drag-and-drop operation with the Hosts file (or Hosts.sam file) into the open Notepad document. Learn all you want about a "Hosts" file:
"Welcome to Ray Marron's Hostess page!" -- a free utility for maintaining Hosts files.
"Gorilla Design Studio" -- Using the Hosts file.
c. The WinSock2 registry key is damaged, [Q811259].
d. The Winsock.dll, Wsock32.dll, or Wsock.vxd file is missing, damaged, multiple copies are present, or one of these files is in the wrong folder. Verify Winsock using the System Information (Msinfo32.exe) Tool, [Q308549].
Utilities which may correct the above two anomalies::
"WinSock XP Fix" (Image) offers a last resort if your Internet connectivity has been corrupted due to invalid or removed registry entries. It can often cure the problem of lost connections after the removal of Adware components or improper uninstall of firewall applications or other tools that modify the XP network and Winsock settings. If you encounter connection problems after removing network related software, Adware or after registry clean-up; and all other ways fail, then "download" and give WinSock XP Fix a try, a 1,412kb file. It can create a registry backup of your current settings, so it is fairly safe to use.
"LSP-Fix" is a free utility that may be downloaded to repair certain problems associated with Internet software when you can no longer access Web sites due to bugs in the LSP software or deletion of software. LSP-Fix repairs the Winsock LSP chain by removing the entries left behind when LSP software is removed by hand (or when errors in the software itself break the LSP chain), and removing any gaps in the chain.
e. Transmission Control Protocol/Internet Protocol (TCP/IP) is not installed or is not functioning correctly, "How to Write an LMHOSTS File for Domain Validation and Other Name Resolution Issues (Q314108)", and review whether LMHOST services are ON, [Q316434].
f. The Internet Connection Sharing (ICS) installation is damaged or is not functioning:
(1) "HOW TO: Configure Internet Connection Sharing in Windows XP (Q306126)."
(2) "Troubleshooting Internet Connection Sharing in Windows XP (Q308006)."
(3) "Time-Out Error Message When You Attempt to Connect to the Web Through Internet Connection Sharing (Q311070)."
(4) "Internet Access Is Restricted After You Upgrade from Windows Me (Q313067)."
g. The Rnr20.dll file is missing or damaged or the "Library Path" value in the following registry key is missing or contains the wrong location:
Note: Jump to "Q241344" listed below.
7. Download and use "IEFix" - a general purpose fix for Internet Explorer (Win 98/ME/2000/XP):
Note: Else, some of the core Internet Explorer ".dll files" may not be correctly registered or need registering. First, verify the exact path of where the Iexplore.exe file is found and used as noted for the "Primary. . ." example. Second, click Start, Run, type exactly "Primary Hard Drive Letter:\Program Files\Internet Explorer\iexplore.exe" /rereg, and then either click OK or press Enter.
a. Registers Urlmon.dll, Mshtml.dll, Actxprxy.dll, Oleaut32.dll, Shell32.dll, Shdocvw.dll, [Q281679].
b. Refreshes Internet Explorer using IE.INF method. Note:
"Unable to Install Internet Explorer 6 on Windows XP (Q304872)"
"How to Reinstall or Repair Internet Explorer and Outlook Express in Windows XP (Q318378)"
c. Initiates "SFC /Scannow" (Win2K&XP), [Q310747].
8. You may not be able to log on to a particular Web site or gain access to certain services at a particular Web site and a message may be displayed or may not, indicating that you must use a supported browser or that the browser used does not support frames, cookies, java, or some other technology, and the browser simply cannot gain access to either the site or to certain provided services. This issue can occur if a Web site blocks certain versions of a browser or any which have known issues with the site. Because of the sensitive nature of some Web site services, site administrators may block any browser they have not had the opportunity to test, or perhaps the browser being used is not compatible with their Web site services or because of options set in the browser make it incompatible, [Q301455].
9. Internet Explorer may display a blank page with a placeholder icon instead of displaying a Portable Document Format (.pdf) file with Adobe Acrobat Reader. This behavior occurs because the Uniform Resource Identifier (URI) to the .pdf file does not end in ".pdf" (for example, the file is opened by using script or the file is dynamically generated) and the content-type header (Multipurpose Internet Mail Extensions [MIME] type) that is returned by the server is "unknown/unknown". Previous versions of IE open Adobe Acrobat Reader as a plug-in, but IE6.x does not support Netscape-style plug-ins, which BTW, could happen with any unrecognized plun-in, [Q305153] and [Q306790].
Note: The article [Q555027] explains that when you try to connect to web site by using Internet Explorer 6 or Internet Explorer 6 with Service Pack 1 - it may open with blank page, instead of web site and the problem could be that some dll's didn't register themselves. Check the registering process in this article as well as downloading and following the instructions for "IEFix" - a general purpose fix for Internet Explorer (Win 98/ME/2000/XP).
10. In Internet Explorer 6, the Restricted sites "zone settings" have been changed:
Active Scripting, is set to Disabled.
Java Permissions, which is located under the Microsoft VM heading, is set to Disable Java.
Script ActiveX Controls marked as safe for scripting, is set to Disabled.
Allow Meta Refresh, is set to Disabled.
Warning: The settings which contains the "Java permissions" subheading (that are located under the Microsoft VM heading normally) are not present if the Microsoft virtual machine (Microsoft VM) is not listed by Default. If the Microsoft VM is installed as a stand-alone package or by means of "install on demand", these settings are then used. By default, the "Restricted sites" zone is used by Microsoft Outlook Express 6 and is used to restrict active content in Hypertext Markup Language (HTML) e-mail messages, [Q300443]. Determine if the scope is a JAVA problem by accessing the "MSN Java Web" site. If the Java program operates correctly, the problem is probably specific to a Web site. Otherwise review the troubleshooting tip in the MSDN article to assist in determining a possible solution, [Q168806]. Download "Microsoft Virtual Machine for Internet Explorer (Build 3802, released 1/25/01)" for all versions of Windows.
11. Incorrectly configured or non-functioning firewall or proxy software. Please read, "Description of a Personal Firewall (Q321050)."
12. When receiving an error message referencing script errors, it could be caused by any of the following reasons and whether a corruption of this sort is cause for a page not being displayed is anybody's guess, [Q283185].
Corrupt or outdated video card drivers.
Corrupt or outdated scripting engine.
Outdated DirectX component.
Corrupt Internet-related folders.
13. Internet Explorer 6 will notify you of Web sites that do not satisfy the browser privacy settings. The Microsoft Knowledge Base article [Q283185] describes how to manage privacy (or cookie) settings, and the article [Q293222] provides information about the default privacy settings in IE6. Otherwise see the MSDN article, [Q196955] for how to set and customize cookies settings in Internet Explorer.
14. If the address in the system registry pertaining to Style Sheets has become corrupted or is missing, some Web page may be poorly formatted (font sizes may be too small or mismatched, words may overlap, or colors may not be displayed as expected) and perhaps the Web site simply does not display, [Q183717].
15. If you install the preview edition of Morpheus version 188.8.131.52, you may receive the following error message which is most likely to occur when you click a link in an e-mail message or when you paste a URL in to the Address bar, [Q321923]:
Internet Explorer has encountered a problem and needs to close. We are sorry for the inconvenience
16. The article [Q885355] explains that when the by default Use smooth scrolling option is enabled, the following anomalous behavior can occur:
When you scroll through a Web pages, the CPU Usage meter in Task Manager may indicate 100 percent CPU use.
Other programs may slow down or become unresponsive. For example, if you play a video DVD, an audio DVD, or an audio CD while you scroll through a Web page, you may experience video or audio distortion.
