I have a custom membership provider in Sharepoint. My issue is that I
changed an incorrect email in the table it pulls the membership info.
from. But that change has not reflected in the site.

I know there are long term fixes with the membership provider
properties. But I'm not looking to change the DLL at this time.

I just need to do a "one time only" sync with the database where the
info resides.

I'm assuming the info is chached or in a cookie. And I don't know how
to clear that so that it goes out and retrieves updated info from the
DB.

Anyone have any ideas on how to "one time do this"? is there an ASP.NET
or SP command to do that at command prompt?
