[SOLVED] slave DNS issue

[azer]

I have a slave server running(was working yesterday), and a win7 client which uses this slave as its primary DNS. but today when im on the slave server and try to use the host command to test out if it can find hostnames, not working. msg is "no servers could be reached." But the thing is when i use the nslookup up from the win7 wich is only using the slave for DNS theres no issue. when i restart named service i get this

Hint: Some lines were ellipsized, use -l to show in full.

Then i do it again and it seems to be running fine.
