Windows 2003 Server SP1 Blocking Internet Access

Discussion in 'Windows Networking' started by Alan van der Vyver, Jun 16, 2005.

  1. Hi!

    I installed Windows 2003 Server SP1 onto a machine running a
    non-Microsoft mail server. Everything seemed fine, except that the mail
    server was inaccessible from the Internet. As we needed a quick
    resolution, we removed the service pack.

    Yesterday I installed the service pack on a machine runing a
    non-Microsoft FTP server and a few IIS web sites. Everything appeared to
    work fine from within our network, but again, nothing was accessible
    from the Internet.

    No other configuration changes had been made and I checked that the
    Windows firewall was off. As there is no obvious cause of this I don't
    know where to look to resolve it, so I again uninstalled service pack 1
    and everything worked fine again.

    I really would like to know what the problem is or what configuration
    needs to change, so I can keep the machines up to date. I expect it is
    something trivial and obvious, but I don't know what it is and I can't
    find any other references to the problem.

    Any suggestions would be appreciated.

    regards,
    Alan.

    Just guessing - check the web service extensions settings in IIS. Your
    applications may be using libraries or script files that are prohibited by
    default, and perhaps the SP reset those settings....
