Network Credential and Webpage could not be found error

Windows XP and 2008 offer the ability to save credentials for websites and other network resources. Yes this is good to know if you have the following problem:

You want to manage your SharePoint Server and each time you enter the url of your SharePoint Site a credential  window pops up of a user who possibly installed something on the server and saved his credentials.

You say huh and try to delete the browsing history of your browser. Nothing changes and the credential window pops up if you type the url. You notice that this happend only if you want to surf to the url and not when you type another url which is used for the same webapplication.

More worse is when nothing happens. You only see a message with "The webpage could not be found". You check your IIS and everthing seems fine. No error messages. Probably you see in the IIS logs a user which you don't know.

The problem is that someone saved his credentials for the url. To delete these crendentials click Start then run and type: rundll32.exe keymgr.dll, KRShowKeyMgr

Delete the url from the upcoming window.


Great find, I’m going to have to check this one out. Thanks for sharing.
