    Clear IE7 DSN Cache


    I'm using a dynamic dns for one of my hosts that has dynamic ip. The problem appears when I'm changing the ip and the dns is changed. If I do not restart internet explorer it will still try to connect to the old ip.
    I've tried ipconfig /flushdns but it seems IE7 has its own cache.
    I can not restart the IE7 window so I'm looking for a solution to either disable IE7 cache or notice the IE7 window programatically by sending a message to all instances of a change in the network settings.
    Please advise.

    Ok, I thing I got it. To be useful to others that are having problems with the Internet explorer's own DNS cache (not the resolver's cache).
    I have added in the registry location
    HKeyCurrentUser\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings
    the following three keys
    DnsCacheEnabled  0x0 (REG_DWORD)
    DnsCacheTimeout 0x0 (REG_DWORD)
    ServerInfoTimeOut 0x0 (REG_DWORD)
