I cannot access a shared drive on a Windows XP Pro machine from a Windows 2000 Pro machine via Peer-to-Peer. Both machines belong to "WorkGroup" and can see each other. When I click the Windows XP machine on the Windows 2000 box I am prompted for a username and password. I put in the username and password I created on the Windows XP box (that belongs to the administrator group) and it won't take. After 3 attempts, it tells me the referenced account is locked out. I check the Windows XP machine and sure enough, the account is locked. I know I am using the correct username and password, so why is it locking the account? Any ideas?
