[Samba] Windows admins "upgraded" network so Samba is no longer working ...

[Jamie Risk]

I'm a long time user of Unix OSes, and new to Linux/Samba administration.

The Window's administrators have changed all logins to domain based and as
such, my previous configuraiton of Samba no longer is viisible in the
network neighbourhood.  (If I log into my machine locally, everything works
great with teh Samba server but nothing on the windows side is conveniant).

Could someone push me in the right direction vis-et-vis documentation?  If,
by chance, the above is a clear picture of my connectivity issue, don't be
mislead into thinking I know what's going on.

Should interested helpers wish to see configuraitons files other than what's
below, I'll e-mail them directly.

Samba 2.2.7a
Linux version 2.4.20
gcc version 3.0.3

This is what previously worked...

[global]
        netbios name            = BIGSERVER
        workgroup               = WORKGROUP
        local master            = no
        log level               = 1
        encrypt passwords       = yes
        log file                = /usr/local/samba/var/samba.log
        server string           = "IBM Box in the server room"
        security                = user
        hosts allow             = 192.168.1. 127.

[public]
        path                    = /home/risk
        browseable              = yes
        guest ok                = yes
        read only               = no

[risk]
        path                    = /home/risk
        browseable              = yes
        guest ok                = yes
        read only               = no
