don't forget, on a workgroup, each computer has its' own SAM (Security Accounts Manager). Therefore, if you're using on xp, username/pw of joe/blow, you have to add the user joe/blow to your 2k machine, and visa versa. Also, make sure you assign permissions to that user to the folder you want to share on windows xp. Windows XP doesn't have the group Everyone set as the ntfs permissions for everyone, Win2k does, however. You can always use simple filesharing, which should actually be enabled since you're in a workgroup, so all you have to do, is modify the share level permissions, which is already set to allow everyone. Everyone including guests, which is what the everyone group is for, which you can use by enabling the guest account, which means you don't have to be in the same workgroup to access the other groups resources. Hopefully this was throughough (however you spell it) enough for you. Cheers!
