I don't use a Squid proxy but you can try mapping root to Administrator.
Create the following file /etc/samba/user.map. Add '!root =
DOMAIN\Administrator DOMAIN\administrator' without quotes. In your
smb.conf file add under [global] 'username map = /etc/samba/user.map'
without quotes again.
Any reason to run such an old version of Samba? It's end of life.
