Search is working fine on one server but not giving results from other servers. moss 2007?

hi,

we have multi server or wfe architecture. configured search service on one server 01, central admin is 02, and query as 03, now crawled content with hostname:port of 01. everything is fine.

but now when we trying to search results its giving results on server 01 which is index and query role. but didnt return any results in other servers.

help is really appreciated.

Thanks,

SJ
