1. The article [Q870700] explains how to troubleshoot problems accessing secure Web pages with Internet Explorer:
? Network connectivity issues
? Look for third-party firewall or antivirus programs
? Turn off the pop-up blocker
? Delete the contents of the Temporary Internet Files folder
? Configure security, content, and advanced settings in Internet Explorer
? Use the System File Checker (Sfc.exe) tool to scan all files that are protected by Windows File Protection (WFP)
? Third-party browser extensions
? Create a new user profile
2. Click Start, Run, type ncpa.cpl, and then press ENTER. Click the Local Area Connection in the right window pane and look to see what is displayed at the bottom Details of the first column of the Network Connections context window. You should see a connection, whether connected and firewalled protected, including the network controller and IP Address.
3. It the Details does not show a proper connection, what happens if you repair it? Right-click the Local Area Connection and select Repair which may or may not restores the connectivity of your network connection. Repair operations attempt to refresh the stored data related to the connection and renew registration with networking services. Repair is used to issue broadcast renew of the Dynamic Host Configuration Protocol (DHCP) address, flush the Address Resolution Protocol (ARP), NetBIOS and domain name service (DNS) local caches, and reregister with Windows Internet Name Service (WINS_ and DNS.)
4. "You receive an error message in Internet Explorer: "Internet Explorer cannot display the webpage" (Q956196)."
5. The article [Q314067] explains the procedure that you can use to troubleshoot TCP/IP issues depends on the type of network connection that you are using and the connectivity problem that you may be experiencing. Use either the instructions in the topic Automated troubleshooting or simply click Start, Run, type netsh diag gui, and then press ENTER.
Note: As instructed, "look for any items that are marked in "RED", expand those categories with the small plus in front, and then view the additional details about what the testing showed" and if you have further question concerning "FAILED" items, included them in your subsequent posts -- any item(s) displayed can be highlighted and copied.
1. Download and follow the instructions for "IEFix" - a general purpose fix for Internet Explorer (Win 98/ME/2000/XP) which:
a. Registers Urlmon.dll, Mshtml.dll, Actxprxy.dll, Oleaut32.dll, Shell32.dll, Shdocvw.dll, [Q281679].
b. Refreshes Internet Explorer using IE.INF method -- two additional notes FYI:
? "Unable to Install Internet Explorer 6 on Windows XP (Q304872)"
? "How to Reinstall or Repair Internet Explorer and Outlook Express in Windows XP (Q318378)"
NOTE: Read and understand what RESETING Internet Explorer means in the article "How to reset Internet Explorer settings (Q923737)"
c. Initiates "SFC /Scannow" (Win2K&XP), [Q310747].
Caveat: Using IEFix myself, the utility does not suggest or require a reboot but I do suggest that you do. In addition, if an extra icon for IE is located on the Desktop afterwards you may delete it.
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 this example. Second, click Start, Run, type exactly "(Hard Drive Letter):\Program Files\Internet Explorer\iexplore.exe" /rereg and then either click OK or press Enter.
2. Reinstalling otherwise:
a. First, be familiar with "Information About Internet Explorer Setup (Q256340)". Second, click Start, Search, All Files and Folders, More Advanced Options, enter a check in Search Hidden Files and Folders, Search System Folders, and Search Subfolders. Type ie.inf in All or Part of the File Name box, select C: in the Look In drop-down menu or the letter of the hard drive containing the Windows folder, and then click the Search button. Find the file labeled ie.inf in the result pane. Right-click this file and then from the context menu, select Install.
b. The article [Q304872] states that when you try to install IE6, you may receive an error message that can occur if it has already been installed and the installation package does not contain any new customizations -- a customized versions of Internet Explorer 6 that was created by an Internet service provider, Internet content provider, or a corporate administrator that is installed instead of the default browser.
3. Fixing connectivity/WinSock problems:
a. WinSock XP Fix 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.
b. "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.
