name resolution problem,

I have a pc running on Win98 se and NT server.
By the way, when i tried to ping one of servers by using hostname positioned
inside, the response of ping test came from outside address, not the
internal host. When I tried to do with ip number, it worked very well.

i think that the DNS name resolution come first than WINS server.
I added a match for ip and hostname in hosts.sam to avoid this happening.
But the result was not changed.
NBTSAT -c shows that NetbIOS is set correctly..

Please help me from Anybody who knows the soltion!!

Thanks in advance.
