Unable to start IE 6.0

For the past week I have been unable to start Internet Explorer 6.0. Message to the effect that Microsoft IE has encountered an error and need to restart. I located a Microsoft KB 281679 article “You cannot open a new Internet Explorer Window …” which suggests a correction to the registry (which I made once) and to Start Run Regsvr32 for 6 dlls (urlmon.dll mshtml.dll, actxprxy.dll, Oleaut32.dll, Shell32.dll, Shdocvw.dll). I can then run IE successfully. However, at the end of the day, I leave my PC on but locked and in the morning I need to go through the same process to access the internet. Is anyone familiar with this? The article also mentions the IE Administration Kit (IEAK) that the problem is relaed to a custom install … of which I know nothing. My PC runs W2k, IE 6.0. Thanks
