Hola:

Trata de verificar en modo seguro por si existen virus en tu Pc, aunque para mayor seguridad, deberias desmontar el disco y ponerlo en otra PC que tenga antivirus actualizado. Ponlo como esclavo y dale una buena pasada.

Despues de ello, baja, instala y actualiza los programas CCleaner y Spybot. Reinicia en modo seguro y manda los analisis correspondientes, y de nuevo el antivirus.

Si es posible regresar al Explorer 6, solo tienes que desinstalar el 7.

Suerte

Cierto... tambien recorda que opera siempre esta ahi para darte una mano como navegador.

Ok saludos he desintalado el IE 7.0, me da error IEFRAME.dll/dnserror. Ahora no puedo instalar el 6.0 quiero saber que bueno es el OPERA, me lo han recomendado. gracias

Como navegador NETO Opera es una excelente opcion en cofiabilidad y rendimiento, pero tiene sus contras, sobre todo para navegadores exigentes que estan muy acostumbrados a sus plugins del firefox Safari es otra opcion pero personalmente no la recomiendo. Suerte.

Hola:

Encontre esto en un foro de Microsoft, ojala te ayude.

I am having a problem with the following website:- www.hi5.com . While trying to visit this website I get the following error
Res://ieframe.dll/dnserror.htm#

I am running IE7, I have been able to visit this website since installing IE7, the problem seems to have just occured recently.

Can anyone help?

I was getting this problem when opening IE7, no matter what website I tried it would come up with that message. I reset my router( pinhole on back of router) and everything works fine now.
This seems to be more of a network issue than a specific IE7 problem. Have you tried accessing the site using a different browser or from another machine on your network? If this is successful, perhaps you should double check the network settings in IE7:
Tools->Internet Options->Connections->LAN settings

I ran into a similar problem.
In my case, I was unable to open Compressed Help Modules (.CHM files) with IE7.
I would get "Internet Explorer cannot display the webpage" and the URL would start with:
res://ieframe.dll/dnserror . . .
After some heavy lifting, I eventually found the following KB article. It addresses both types of problems.
You cannot open remote content by using the InfoTech protocol after you install security update 896358, security update 840315, or Windows Server 2003 Service Pack 1
http://support.microsoft.com/kb/896054
In your case, the UrlAllowList registry key should help.
In my case, the MaxAllowedZone key helped.
A key snippet:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"UrlAllowList"="http://www.wingtiptoys.com/;http://www.contoso.com/"
My problem opening CHM (help) files yielded error messages like this:
Cannot Open the File:
res://ieframe.dll/dnserrordiagoff_webOC.htm#mk:@MSITStore:C:\path\sample.chm
My Event Viewer (Application Error Log) had entries like these:
Event ID ( 1 ) in Source ( ITSS )
Event ID ( 1904 ) in Source ( HHCTRL )
In some cases, however, the above fix was not enough.
In those cases, the "unblock" solution described below did the job:
How to unblock downloaded Compressed Help Modules (.CHM)
http://pointerx.net/blogs/glozano/archive/2006/04/06/151.aspx
Essentially, CHM files can be unblocked by clicking "Unblock" from the "General" tab in the CHM file's "Properties" window.

The above link describes security issues involving the InfoTech protocol (A/K/A: ms-its ITS ITSS).
