Update the client setting when network changed

hi ,I have a DSCS95, it was running well several months ago. and today when I want to do some test. I found I cannot enter the client setting page (or any other pages). to enter the page i need enter the password, but it has no response.
because the network config changed( I re-apply for the company testing network config ), so the device has no network connection.
no network → change the setting → enter password → no network so cannot check password → so I cannot enter the setting page.
am I right? pls help

Which setting page are you talking about?
On the DSCS or CMS?
