How is pw_name going to change without a logoff?

Maybe too many requests to the DC for all users?  Couldn't you just reinitialize if the network data changes?  There are times when I would be on the DC and times when I am not with the same account.

A network change event works fine for me but not a timer event.

I'll take to NET plea as well.  I'm doing good to read the list mail.
