If it's in Cache only mode, then there isn't a firewall to stop it from working. Sounds like you have another issue.... Think of ISA in this case as a network bridge with a hard drive.... -----Original Message----- From: Ramdhari, Ravesh [mailto:ravesh@xxxxxxxxxxxxxxxxx] Sent: Tuesday, August 31, 2004 8:52 AM To: [ISAserver.org Discussion List] Subject: [isalist] RE: ISA 2000 Cache Mode http://www.ISAserver.org Hi Greg, I will test this and let you know. However I don't need voice and video, so here's a plus for now. Thanks -----Original Message----- From: Greg Mulholland [mailto:greg@xxxxxxxxxxxxxx] Sent: Tuesday, August 31, 2004 2:09 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: ISA 2000 Cache Mode http://www.ISAserver.org <rant>Obviously we need to make it easier for people to find the right information, short of running "search the web classes" because this topic comes up as much as anything else and the answer is always the same. </rant> Get Jim's msnim.zip file and run the extracted script on your ISA. This will create the necessary protocols for MSN. However, since you didn't say, I'll assume you want to use voice and video, well here's the thing, you cant. Messenger voice and video uses SIP which ISA as yet, doesn't support. Until then your toast, unless of course the person initiating the call is not behind a NAT service, like ISA or some kind of NAT firewall. If you want voice and video try net meeting, works well with ISA.
