The nslookup on "server2" looks ok to me. It's using /etc/hosts and getting an answer.
The problem could be on "server1" not recognising "server2" as a valid server in a secure environment depending on whether the "telnet" is by name or by IP address. This can be a reverse DNS lookup issue on the client or an access control setting ... or something else.
1) Need to ensure that the nslookup by name and IP address for both "server1" and "server2" are totally consistent on both "server1" and "server2".
Also try "telnet" from "server1" to "server2" by name and IP address.
2) Check /etc/hosts.allow and /etc/hosts.deny on "server1" and "server2".
3) If this is not a secure enviroment it might be due to the contents of /etc/securetty (if present) on "server1" but I don't think you get the "not on system console" message from HP-UX.

LOCKTEST(1) Test Suite LOCKTEST(1)
NAME
locktest - Find differences in locking between two SMB servers
SYNOPSIS
locktest {//server1/share1} {//server2/share2} [-U user%pass] [-U user%pass] [-s seed] [-o numops] [-a] [-O] [-E] [-Z] [-R range] [-B base]
[-M min]
DESCRIPTION
locktest is a utility for detecting differences in behaviour in locking between SMB servers. It will run a random set of locking operations
against //server1/share1 and then the same random set against //server2/share2 and display the differences in the responses it gets.
This utility is used by the Samba team to find differences in behaviour between Samba and Windows servers.
OPTIONS
-U user%pass
Specify the user and password to use when logging on on the shares. This parameter can be specified twice (once for the first server,
once for the second).
-s seed
Seed the random number generator with the specified value.
-o numops
Set the number of operations to perform.
-a
Print the operations that are performed.
-A
Backtrack to find minimal number of operations required to make the response to a certain call differ.
-O
Enable oplocks.
-u
Hide unlock fails.
-E
enable exact error code checking
-Z
enable the zero/zero lock
-R range
set lock range
-B base
set lock base
-M min
set min lock length
-k
Use kerberos
VERSION
This man page is correct for version 4.0 of the Samba suite.
