NSH proxy just provides authentication to access a server. You still need to be able to resolve the server name from the local client machine.
Thank you for your response.
I was surprised to hear this and as such opened a support call with BladeLogic to see what options they had for addressing this. It turns out that currently all name resolution does occur at the client level, but that there was a product enhancement request to give users the option of doing this at the NSH Proxy server. I've added my ticket to the list of users who are interested in this enhancement. They couldn't give me an estimated time frame on availability however.
