Assume you have two Windows XP machines, with a different username on
each.

On machine #1, you browse to \\machine2\share , and are prompted for a
username and password. You enter them [e.g. your username on machine2],
everything works.

Now the password on machine2 is changed, and windows keeps trying to
use the old password, which of course fails.

Now suppose that machine2 is on a domain, and the domain has a
5-bad-password-attempt lockout policy. Then you would be where I am.
Every time I try to browse to a share that requires my domain user name
and password (from my laptop, which is not on the domain), I get locked
out - because Window XP keeps trying to use the old password (my domain
password changed today).

It never gives me a chance to enter the new one - it just tries the old
one, and *bam* I'm locked out.

Any idea how to makes windows forget passwords for samba shares?

Thanks!

Found it right after I posted. That's apparently the magic trick.

Control Panel->User Accounts->"Manage my network passwords" on the
left.
