Hi Dan, check out http://www.isaserver.org/articles/ISA2004_ClientAutoConfig.html. HTH, Stefaan _____ From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of Ball, Dan Sent: woensdag 5 april 2006 16:27 To: isalist@xxxxxxxxxxxxx Subject: [isalist] wspad.dat I am right to assume that no authentication is required when the FWC requests the wspad.dat file from the ISA2004 server? Trying to track down some problems, and occasionally requests for the wspad.dat file go unanswered from the ISA server. If it requires no authentication for that file, then I can look at the ISA server closer, but if it does require authentication to get that file I will have to look at both the ISA server and the local DC. -- No virus found in this outgoing message.
