linux/unix admin question

Guys,

I registered a domain name where I work and I forgot the freek'en domain 
name. I know it starts with mic. Is there a way to query a DNS server 
and get it to dump out all its records so that I can then do a search 
for anything which starts with mic? the ls command withing nslookup 
looks to not be implemented...

Cheers and thanks in advance. Steve.
