At Nadia's networking: XP - (no password account) cannot connect to Vista (password account) for file sharing, error: "Logon Failure: Account Currently Disabled"
Found solution:
The solution does seem to be in the 'control userpasswords2' command but for me it
was in using it on the XP machine I added my Vista PC using the Advanced tab, Manage
Passwords, Add and then for server type PCNAME\USERNAME and then you password for
the Vista computer. - Kevin George
After the setting, a pop-up screen for user/password will now show when accessing network folder. One needs only put username (without domain) and password to login. Checking Remember password box might help for future convenience.
