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.

NAME
asadmin-restart-instance, restart-instance - restarts the specified server instance and all the services associated with it
SYNOPSIS
restart-instance [--user admin_user] [--password admin_password] [--host localhost] [--port 4848] [--local=false] [--domain domain_name]
[--passwordfile filename] [--secure|-s]instance_name
Use the restart-instance to restart the instance with the instance name specified. The restart-instance command can be run both locally and
remotely. To restart remotely, the administration server must be running on the hostname and port number specified. The user authenticates
using the password identified for the administration server. Additionally, the instance must already exist within the domain served by the
administration server, and the instance must be running. The restart-instance command is not supported on Windows.
OPTIONS
--user administrative user associated for the instance.
--password administrative password corresponding to the administrative user.
--host host name of the machine hosting the administrative instance.
--port administrative port number associated with the administrative host.
--local determines if the command should delegate the request to administrative instance or run locally.
--domain name of the domain.
--passwordfile file containing passwords appropriate for the command (e.g., administrative instance).
--secure if true, uses SSL/TLS to communicate with the administrative instance.
OPERANDS
instance_name name of the instance to be restarted.
Example 1: Using restart-instance in local mode
asadmin> restart-instance --local --domain domain1 server1
Instance server1 started
Where: server1 is the name of the instance restarted on the domain1 domain.
Example 2: Using restart-instance in remote mode
asadmin> restart-instance --user admin --password adminadmin --host bluestar --port 4848 server1
Instance server1 started

specified.
