If you can’t access a particular web site, but you can open other web sites in your web browser, the most likely explanation is that the web site you’re looking for is temporarily unavailable. It could be that they’re having some trouble with their server or they could simply be updating their site and doing a bit of maintenance.

You might like to add the site to your bookmarks and visit it later – in most cases, it will load up just fine.

If you’re using Windows XP and you’ve chosen Internet Explorer as your web browser, you might encounter problems accessing secure sites, for example an online bank or other site where security is essential. This may be something to do with your security settings. Click here to carry out some basic checks that might resolve the issue.

If these checks don’t help, and you are comfortable with using DOS commands, follow the steps below.

Advanced user?

If you’re an advanced user comfortable with using Windows DOS commands, you can check if this is a problem with your computer’s dynamic link library (DLL) files. DLL files are a collection of small programs that are stored “offline”, so they don’t take up any space on your computer unless they are needed. However, they can go missing, become damaged or not be properly registered.

One method for resolving this is to use a Windows program called regvr32.exe.Regsvr32.exe is a tool that registers the DLL files.

To use Regsvr32.exe, follow these instructions:

1. Click on Start, and then click on Run.
2. In the Run box, type cmd, and then click OK.





3. At the command prompt (shown below), type the following command and press Enter after each one:
   · regsvr32 softpub.dll
   · regsvr32 wintrust.dll
   · regsvr32 initpki.dll
   · regsvr32 dssenh.dll
   · regsvr32 rsaenh.dll
   · regsvr32 gpkcsp.dll
   · regsvr32 sccbase.dll
   · regsvr32 slbcsp.dll
   · regsvr32 cryptdlg.dll





4. Click on OK when you receive the message DllRegisterServer in FileName succeeded.
5. Type exit to exit the command screen.
