Will this have an affect on the internet bandwidth?

You need to be absolutely sure that ISA can resolve internal and external names quickly. There are several articles at www.isaserver.org that discuss ISA and DNS configurations. Also, the type of client request has a lot to do with it as well. Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/Jim_Harrison/ http://isatools.org Read the help / books / articles! http://www.ISAserver.org Well I have been struggling to sort out a problem we have. It seems we have a problem with our bandwidth. For some reason out of the 10MB bandwidth (ADSL) we only ever receive around 2MB. Every user complains "the internet is too slow". We are using Rainconnect to aggregate the bandwidth. We have finally reached the following conclusions: - Either we are receiving DOS attacks - Kazaa or MSN messenger (I think Kazaa) is causing the bandwidth degrading - Or it maybe the ADSL routers Regards Sachin Vaish Vaioni Group Limited t: 0870 160 0650 f: 0870 160 0651 Please note our new address below: 32 Leslie Hough Way Manchester M6 6AJ -----Original Message----- From: Jim Harrison [mailto:jim@xxxxxxxxxxxx] Sent: 29 March 2003 00:51 To: [ISAserver.org Discussion List] Subject: [isalist] Re: DOS attack http://www.ISAserver.org For the most part (proper configuration), ISA is self-protecting. Is there a particular attack you're concerned about? DoS is a generic term referencing any attack that reduces or completely eliminates your network connectivity.
