    The error below occurs periodically when running a webapplication (.net). The
    server is a Windows 2003 and the clients run Windows XP. It is a intranet
    with Windows integrated authentication.

    "The kerberos client received a KRB_AP_ERR_MODIFIED error from the server
    host/pasp1h1.forsmark.se. This indicates..." Source: Kerberos, id=4.

    While you are using the webapplication a loginform popup periodically.
    Sometimes it works to login, but not always. If you leave the webform open in
    IE for about 30 minutes and then return and click some link the loginform
    always popup. It works for a while if you close and reopen IE.

    The iis applicationpool runs under a domain user because the webapplication
    needs to write files on a fileserver.

    We have a testserver where the webapplication works with no problems. I set
    up a new webserver but got the same problem. If I use the IP-adress instead
    of the servername in IE it seems too work. If the applicationpool runs under
    the Network service it also works.

    Thanks in advance for any help!
