i am able to solve the above issue after 3 days.
the main issue is i registered sql server with IP address.
solution is: so i made an entry in the C:\WINNT\system32\drivers\etc\hosts.txt file of publisher server. the entry i made is subscriber server's host name, example '192.168.10.33 FS6'.
and then registred sql server with the name FS6 instead of instead of using IP address. And then i set up transactional queued update replication, it's working fine.
thax and regards
