The Web Proxy service (W3proxy.exe) may intermittently cause access violations with error 0xc0000005. If you take a network trace, you see that a DNS response is returned to Internet Security and Acceleration (ISA) Server immediately before the access violation occurs.
The DNS server that ISA Server is using returns an "A" record in response to a PTR record query. This is incorrect behavior by the DNS server. However, the DNS resolver permits the information to pass to ISA Server.
