Hi Arthus, Some things to consider: 1. Content download jobs 2. Active Caching 3. Spyware, scumware, malware on your clients or servers 4. Someone running warez software (Kaaza, et.al) on one of their desktops Do a netmon trace on the external interface and see what's happening.

[mailto:alim@xxxxxxxxx] Sent: Tuesday, February 25, 2003 9:12 PM To: [ISAserver.org Discussion List] Subject: [isalist] Slow connection http://www.ISAserver.org We've been experiencing slow internet connection lately, when I checked our utilization using the MRTG, I noticed that we're taking so much of our bandwidth on outbound connections. This is weird because yesterday is a non working holiday here and we still experienced the same thing. There are some things that I suspect have caused the problem: Maybe there's a problem with our ISP, or somebody is using our connection without us knowing, maybe holes in our configuration which I would like to check. In this regard, may I ask what are the things that I should look for and check for in our system? How can I tighten up our proxy/firewall? We're just using ISA as our firewall? Hope you can help me folks! Thanks a lot! ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Exchange Server Resource Site: http://www.msexchange.org/ Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
