HP-UX

1)MY HP-UX11iv2 machine is on a specific subnet as in rrr.rr.199.( its a rp3410 blade server).It has 2 hard disks one of them has HP-UX11iv2 and the other hard disk is not being used
2)ip of the hp-ux machine is rrr.rr.199.rrr
3)i need to access this hp-ux machine remotely from a windows machine on the same subnet,as in from a windows machine that has an IP address set to rrr.rr.199.***
4)I use putty or xmanager to connect to the Hp-UX machine remotely.
5)The issue i am facing is , the hp-ux machine comes into the network and goes out of network randomly as in i can connect to the hp-ux machine remotely once from windows, but the network connection gets disconnected after 2-3 minutes.I have a lot of Non windows machines(RHEL,Solaris) in the network, they do not give me this problem.
If i try to re-connect it says connection refused.
any help would be greatly appreciated

Thank you

What about connecting to the HP via a RHEL, or solaris, same issue?

Have not tried the same, but i would want to connect from windows only.

Just an FYI. rp3410s are not blade servers. They are rackmount boxes. Blade servers go into enclosures that are managed separately.

Have you checked the ssh logs to see if there are service interruptions? When you are unable to connect, what does a trace route show you? Can you ping the machines?
What are the settings for Putty? Can you perhaps install ethereal/wireshark on your windows machine and see what happens by doing a packet capture when connecting?
