This is Linux, there are several ways ;-)

Two that spring to mind are (both run on what you think is a DC):

ps ax | grep '[s]amba'

host -t SRV _ldap._tcp.dc._msdcs.$(hostname -d) | grep $(hostname -s)

If you get any output from the first, it is a DC. Same goes for the 
second, but it will also work on any Unix domain machine if you remove 
the pipe '|' and anything after it.
