First, if you want to share a device/drive, right-click on it, and choose Sharing and Security.
Now, in XP, there's a setting called 'simple file sharing'. I recommend turning it off for now, so that way you'll see exactly how sharing works.
Open My Computer, go to tools, folder options, view tab, and all the way at the bottom, uncheck simple file sharing.
Okay, now if you want share anything, right-click on it, and choose sharing. Then share it. You can also specify who you want accessing it, but by default, it will give everyone access.
next step is to make sure that there are valid user accounts on both machines. For example, You log in as Joe Blow on the XP machine. If you want to share something on the 2000 machine, you'll need to create a user account for Joe Blow and assign him the same password.
This goes vice-versa for sharing on the XP machine. If Bob Smith logs into windows 2000 and wants to access something on the xp machine, then he'll need to have an account created on the XP machine.
The other thing that comes into play here is if the machines can 'see' each other. You are using a router and by default, it should configure both machines to see each other. You can test this by going to start, run, and typing \\name of the computer. For example, \\WINXP
This will show you all the shared devices on here. You then double-click on what you want to use, and you will be prompted with username/password. Enter the same username/password as the user that's currently logged in.
