I just received my new machine, and immediately after I assigned it to the domain I began downloading my programs. I quickly noticed that the file download speed is severely handicapped. I'm on a 1Gbps connection local area and a 50Mbps wide area, and neither will climb above 250Kbps, normally sitting around 96Kbps.
I did some troubleshooting, reset TCP/IP and Winsock, turned off IPv6 (incl. registry edit), etc. I finally started in Safe Mode with networking, and the download speed jumped to normal speeds. So I went back to normal startup and disabled all startup services, and the problem persisted.
Finally I started working on normal services, and narrowed the problem down to "Parental Controls". Weird thing is the service is stopped, however when I disable it, the problem is gone. Keep in mind that on a Domain controlled machine, Parental Controls shouldn't be running, which it's not. But somehow, it's still affecting file download speed.
Any idea why it is affecting it, and how I can fix it without disabling the service? (in case the machine gets moved to a home office). I've contacted Dell, and they've never seen this problem and don't have an idea of how to fix it, short of a clean OS install.
Windows 7 Ultimate x64, not on SP1 yet (got an alert it was buggy, and I can't really download it yet anyway).
