Question: I have a Windows XP Pro SP2 computer that is consistenly getting about 500 Kbps download on bandwidth tests. On another computer running W2K3, I am downloading at about 2,800 Kbps. It's 3Mbps DSL, so the server seems to be getting about what it's supposed to. They are both connected to a Watchguard X5 firewall.

On the XP computer, I have tried switching to the cable that the server was using, but that didn't change anything. I have tried adding a different network card, but same result. I have restarted the computer, disabled the firewall, disabling all non-MS services, I tried disabling all startup items, and rebooted the firewall. Still same problem. There shouldn't be anything slowing it down. Both machines are running 10/100 NIC's in auto negotiation. Being that they were both plugged into the same router, I can't imagine that is the issue. What else could the problem be?

The next thing would be to check the MTU settings on both - My XP Pro is 1300. Now I haven't looked at this since 95/98 times, but as I recall the optimum setting was 1500. Check what it is in 2003. There are tools around for this, but most are old, I can't see anything I would care to use on XP at this point. Anyway if the settings are the same then this isn't the problem. If you do a regedit search, the MTU settings are towards the end, so it will take a while to get there.
