we have BaaN IV c4, it is running on AIX4.3-12 , we use hosts file to resolve computer Name, we start to use DNS Server on Win2k3 , So I enabled DNS on AIX Server which becomes able to resolve computer name by using the new DNS Server
my Questions is although AIX OS. can resolve all Computer through the DNS, but BaaN can't able to validate some of those computer, while I resolve them through AIX O.S by using nslookup command
please if you knew any answer feed back me

What do you mean by Baan is unable to validate them?

What does your /etc/nsswitch.conf look like?

In my opinion it depends on the parameter of the rexec daemon. When rexec runs without the parameter -c, only clients can connect to the Baan-system when they have an entry in the /etc/hosts. Please check your entry in the inetd.conf file an start your rexec with the parameter -c. I think this solve your problem

See Baan solution 6443 for more info on rexec -c as suggested by gk1234.
