NT Domain authentication's

[Purcell, Charles E]

Recently our Unix Administrator installed Samba v.2.07.  It was configured
to attach to our NT domain.  When this occurred we started to experience
problems with user authentication's to the domain and it appeared that the
"Samba" server had become the master browser.

Have you seen this problem occur at other sites? If so, what is the work
around?  

 We have been using  Samba v2.06 on another server for about two years
without any similar incidents.
