I have Windows 2003 server and ADSL 2Mb/s internet connection. Also I have a LAN with 2 XP computers, only one laptop (sometimes appears in network).
Also I have licensed Agnitum Outpost Firewall 2.1 on this win2003 server + some plugins.
Usually I download some working data from ftp servers and so on... Then I have a very strange problem: when I reboot server and dial DSL, internet connection works very fine - very quick, I can connect to all my ftp and mail, but after some time, perhaps 3-4-5 hours, internet become very slow, connections are slow, I.E. opens pages very long, I can't connect to my ftp's and mail servers, but, if I was previously connected to some ftp, speed stay good.
I can't find what the problem is, but I mentioned, if I am not using inet at all it stays in good speed. Before, when in my server was Win XP I didn't have such problems.
