IE/Chrome w/ proxy pac file causes huge delays when not going through proxy
having a bit of an odd issue here at my company, let me give you some background.
we have a proxy server and apply IE proxy settings via group policy for everyone to point to a pac file. then within the pac file if your IP lies within a range that our office networks are in, you goto the proxy, otherwise go direct. the pac file is located on one of our file servers.
now my issue lies with 1 computer. With all other hundred or so laptop users this isnt an issue. but for this one person, whenever he tries to connect to the internet outside of the office, it takes about 2 minutes for his homepage (google) to load, after that initial load the internet seems to be okay...here is what i tried so far:
1) IE master reset
2) different domain user on that laptop and that user on a different laptop, the only constant was this laptop is slow to timeout to the proxy.
3) install chrome, same issue, but chrome's status bar says "resolving proxy" during that wait period.
one "dirty" fix we thought of the resolve this is for this person to put the proxy pac file local, so that it doesnt wait the 2 minutes to timeout, but we want to avoid that and i havent tested it yet. ideally i'd like to get some suggestions here, try them, then if it comes down to that nothing else works, we would go this route.
so anyone know any tricks or registry fixes that may resolve this proxy timeout issue?
Cause on all of our other laptops, when outside the office and using the computer, the proxy can't be reached, so it timeouts and it loads the webpage, it seems instant. thank you in advance.
