WindowsXP hangs at startup because my DSL is plugged in

Here's a tricky one. Becaues I have DSL plugged in, my windows xp pro sp1 hangs when windows starts; I can't go into my computer or open explorer for about a minute and then every thing goes back to normal.

When I leave my DLS UNplugged, everything starts up normally.

I've had this problem for about 3 years over two different DSL providers, two different computers, two different lan cards, many different re-installations, and with many different friends that have totally different computers but the ONLY thing thats in common is Windows XP.

I have updated drivers for lan, chipset, windows patches, my startup is clean, i've defraged, no harddrive errors, no device manager conflicts, no spyware, no virus, my computer is squeaky clean. Even with black vipers service configuration and without. Lastly I'm not on a network, only user, and I have no printers or scanners.

The only solution I can come up with is some network setting, special windows patch to fix DSL users, or some bootup (non-startup item) option conflicting with network settings. It can't be anything else.

Thanks for any help. =)

EDIT: PROBLEM SOLVED![/u]

The solution below stoped that hanging I was experiencing during windows startup:

start/control panel/network connections/right click Local Area Connection/properties

Click on internet protocol then properties.
Dot "Use the following IP address" and put in 192.168.1.10 for IP and 255.255.255.0 for subnet mask.

This solution came from dslreports.com, here is the link:

Thanks to everyone who tried to help. =) I'm so happy that I don't have to live with plugging and unplugging dsl everytime I restart windows! =)
