Hi. I installed Small Business Server 2000 at a client site. They are using ISA server to access the Internet and Email via a dial up connection over modem. I have the DUN entry to disconnect after 5 minutes inactivity. The dial up connects rarely and when it does, works fine for a few minutes but will disconnect after a random period of time. It happens with several ISPs. Have I done something wrong or missed something? ANy advice much appreciated.
