If you have any rules implementing username-based authentication through the firewall service they'll kill your macs, that can only happen when using the firewall client. Only the web proxy service will do username-based authentication without the firewall client. Also, although I don't think it's your problem here, you can only use Basic authentication with Macs. -Shawn ----- Shawn R.

A problem I am having presently, is our Mac clients (using POP3) in regards to retrieving their e-mail. They can retrieve their e-mail - BUT they are not able to SEND mail - and they have SMTP authentication turned on (because it's required by their ISP). I am not sure if the SMTP auth is adding another level of complexity to the situation - but turning it off is not an option. Are there any tidbits of information you can throw my way, or any articles that will explain all of the ins and outs of running Macs in a ISA 2000 environment? I know there are no ISA Software Clients for the Macs (which is really unfortunate) - and they are forced to run as a Secure-NAT clients which under normal circumstances, *should* be good enough. BUT in this case, hardly anybody can send e-mail - and of course, the PC's work flawlessly. I don't want to sound like a Mac Basher, but why must EVERYTHING be so darn difficult, the moment Macs enter into the picture???? Thanks very much in advance for any info you can offer.
