If you are on the network there is a good chance that the DHCP is configured to assign a default domain and alternate 
search domains
Winipcfg /all on windows - look for connection-specific DNS Suffix
Review the /etc/resolv.conf for a search entry and IP addresses for DNS servers

That's true but you still have to know the internal domain name :-)

These solutuons are useful, but you're assuming a machine joined to
the domain, running in the context of an authenticated user session,
with knowledge of the internal domain name.

Indeed.
Similar to ethe cho %logonserver% method is:

Systeminfo | findstr /I /C:"logon server"
But a nice way is to get it from dns:
Nslookup -type=srv _ldap._tcp.pdc._msdcs.<domainname>
Will give you the same answer as logonserver, to see all DC's change
pdc to just dc. I got 8 DCs doing this at work all of which I know are
dcs

depends on how auth'd you are to the domain I guess, but dsquery is
very useful too

Hi
I'm wondering what techniques people are using to detect domain
controllers when they get on networks. I've asked a few people and
the
standard answer seems to be to look for the DNS server as the PDC is
usually also acting as the DNS server. Has anyone else got any
better
or alternative techniques they use?
