Hello Everyone I am trying to diagnose a problem with either the PC, Firewall Client or ISA I have a simple program that seems to work without the firewall client enabled, but when it is enbaled, it fails to function. I just checked the PC in question and found a FIREWALLC.LOG file, but this only contains info on the install and not telling me anything about what the firewall client is trying to do! Is there anyone that can help me find additional information, so that I can try to see where the problem lies! IF the client is disabled, program works IF the client is enabled, just sits there for hours and hours..... Thank you everyone Simon Weaver Technical Consultant MCSE+Internet / MCSE Windows 2000 Integrated Solutions Corp. Ltd http://www.iscl.net <http://www.iscl.net/>
