Is it just that site that you're having trouble viewing, and is hte problem just with one computer?
If so, try flushing out your Temp and Temporary Internet Files folders. You can empty your Temporary Internet Files folder from the Internet Options control panel, but I prefer to delete everything manually just to make sure I've completely flushed things out:
- Reboot into safe mode (you get to the safe mode boot option by hitting the F8 key as your computer is starting up)
- Open Windows Explorer, and in the Folder Options->View settings under the Tools menu, select "show hidden files and folders", and uncheck "Hide protected operating system files".
- For every user account listed under C:\Documents and Settings, delete the entire contents of these folders:
1. Local Settings\Temp
2. Cookies
3. History
4. Local Settings\Temporary Internet Files\Content.IE5
- Delete the entire content of your C:\Windows\Temp folder (in Win XP) or C:\WINNT\Temp folder (in Win 2000)
Note- If you get any messages concerning the deletion of system files such as desktop.ini or index.dat, just choose to delete those files; they'll be automatically regenerated by Windows if needed. Windows will allow you to delete the versions of those files which exist in sub-folders within the main Temp/Temorary folders, but might not let you delete the versions of those files that exist in the main Temp folders themselves; this is normal and OK.
- Empty your Recycle Bin.
- Reboot normally.
