Hi CS,
There are a number of possibilities, small issues with internet connectivity
beyond your control are the most likely. But the 1-5 AM is a bit of a clue
also, as the server is busy for short bursts of time with maintenance tasks,
Exchange maintenance being one of them.
I remember the POP3 connector being a good indicator of when the ISP was
having difficulty ;-). I could tell them, with 15 minute resolution, when
the internet connection was flaky.
I've learned to trust SBS, and the issues you see do indeed point to
internet connectivity problems. But there's most likely not much you can do
about it, short of trying another ISP - or another grade of service.
If you like, give us some detail about your connection type and network
topology. (single or dual nic, router/firewall, xdsl/cable/other, static or
dynamic IP, name of ISP. Some basic information on your server hardware may
also be helpful.
