Now this is rather unusual but possible ;-)
Since we don't know what the error is, it's kinda difficult to guess.

The correct method is AFAIK "vos changeaddr ..." which is precisely
what you did.
You can remove the entries for the volumes of the server in question
by using "vos delentry" than _fix_ your address problem
start the fileserver and use "vos syncvldb". Of course you can't do
this on a production server. Maybe you want to move the volumes to
another server, or something.
If you don't know where to put VosRestrict, call the fileserver using
strace and watch where the fileserver is trying to open the file.
