rm | help me, obi-wan kenobi and why the fuck aren't you taking my calls? -- router problems part deux

Thank you for all those kind suggestions, unfortunately, they didn't work.

Here's more of the nitty gritty details.

My computer, running Windows 2000 professional, is connected to th router with a wire. This is successful, and I have internet access.

Megan's computer, running Windows XP, is:
- connected to the router (when i log into the router I see her)
- can see the good signal strength from the network
- currently sporting the proper IP.

Only problem is, she still can't get to any websites. She's dicked around with the firewall stuff, and doesn't think that is the problem, but stumbled on something just now, that when she tried to change it said she didn't have Administrator priviledges. The thing is, there is only one account on her computerm "Megan" -- no Administrator. She is the Administrator. is there some secret account she needs to get into? How? I don't know XP for shit.

Thnx.
