Outlook clients offline after applying SP2 on a windows 2003 Serve

  1. Hi all,

    Anyone can explain what the server firewall per port feature included in
    SP2 does for the 2K3 server? We recently updated to Windows 2003 server SP2
    from SP1 on an Exchange server (version 2K3 Sp2) that also serves as
    sceondary DC/DNS.

    After that some Outlook clients, were not able to connect to Exchange and
    goes offline. It was resolved by going to security setings of the Outlook
    clients and selecting NTLM password authentication from the default setting
    of Kerberos/NTLM authentication. I suspect it was something to do with the
    firewall per port included in SP2. Funny thing is, I know I checked that the
    server is not running Windows Firewall after the upgrade. Appreciate the
    inputs. Also is it ok to leave the current Outlook client setup as is?
