Hi Asif, Problem #1: That error is being reported by msiexec (the windows installer app), not the FW client. What is different between the working and non-working machines? The FW client installer is coming from the same place, so it can't be that. Problem #2: 1. don't use the ISA as a workstation; it breaks you carefully-crafted security model. 2. to allow web browsing, enter "localhost:8080" in the IE proxy settings on the ISA 3. to allow non-proxy apps, create packet filters Problem #3: NAT is built into ISA; if you mean "use secureNAT", then take a read in: http://isaserver.org/authors/harrison/tutoials/isa-clients-part1.htm http://isaserver.org/authors/harrison/tutoials/isa-clients-part2.htm http://isaserver.org/authors/harrison/tutoials/isa-clients-part3.htm Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/authors/harrison/ Read the books! ----- Original Message ----- From: Asif Bakali To: [ISAserver.org Discussion List] Cc: fareed@xxxxxxxxxx ; sherrera@xxxxxxxxxx ; jim@xxxxxxxxxxxx Sent: Thursday, May 02, 2002 1:14 AM Subject: [isalist] Win 32 Application Error http://www.ISAserver.org This is a multi-part message in MIME format. ------------------------------------------------------------------------------ Hi I'm a little confused on all the terms here....
