If so, Microsoft has this article about what to do next.
And the answer is no. No one, including Microsoft has issued tools to diagnose or fix misbehaving accounts. This is how things are.
I have three users on my desktop runing MS XP and IE 8. My son, husband and myself (the administrator). The pages in IE 8 display perfectly on my son and husband's user accounts. When I access IE 8 as my user, it is always missing headers or links and sometimes graphics. I have tried disabling add-ons and reenabling them one at a time, disabling the Avanquest firewall and virus potection, checking the IE 8 options against each user logon for differences, uninstall IE * and reinstalling IE 7, cleaning the registers with two different tools, searching the Microsoft Knowledgebase, and other options that I cannot even recite. I have reached my frustration level. This problem has been occuring since I had to restore the computer. My son downloaded a virus onto the computer so I ended up restoring the system and reinstalling most programs, and recreated each user, reinstalling MS Outlook Express, and copying my email /messages and my IE links from backups. I have Windows XP on a Dell computer that is several years old. A good example of the problem is the www.yahoo.com page. On my son's and husband's logon the page is displayed perfectly with a grayish blue background and all of the links and pictures visable. My yahoo page is a white page and looks like a skeleton with no background color. The links I have tried, seem to work fine. On other web sites the header and header links are missing. I have researched the problem and tried every option I have read without any luck. I just don't understand how IE 8 and previously IE 7 can work on two out of three logons. I use my user account for my business and desperatly need to fix it. I would greatly appreicate it if somonee could tell me how to resolve this problem.
