For some reason the firewall service on our ISA server is not working, the only error messages I can see in the event is related to not being able to create a packet filter, could this be part of the problem? The Web Proxy has no problems accessing the Internet so there is no problem with the ISA server actually accessing the web but firewall clients cannot connect to any service such as POP mail or Terminal services. Has anyone experienced this before? Can anybody help?
