Much reading to be done, grasshopper: www.isaserver.org www.microsoft.com/isaserver NLB and CARP can conflict because of the potential for a connection loop: - user needs to make web request - CARP directs client to specific server name (resolves to VIP) - user requests content from VIP - ISA serving request doesn't have the content; makes CARP request to other array member (resolves to VIP) - ISA making request gets own request; throws "proxy chain loop" error - user gets pissed and throws PC out the window - user gets fired and arrested; problem solved ------------------------------------------------------- Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/Jim_Harrison/ http://isatools.org Read the help / books / articles! ------------------------------------------------------- -----Original Message----- From: klocke [mailto:kevin.locke@xxxxxxxxxxxx] Sent: Friday, April 01, 2005 10:25 To: [ISAserver.org Discussion List] Subject: [isalist] ISA 2004 EE http://www.ISAserver.org Can somebody please a explain to what would be best to a very new ISA admin. I have been tasked with replacing our old Proxy with ISA 2004 EE. The requirment are that the it needs to be fault tolorate and it for Web proxy only. My thoughts were to create ISA in a array with CARP for web caching and also us NLB on internal NIC's for the fault tolorate. But I have seen a few article recommending not to use NLB with CARP? can you please explain.
