Sun Networking Services and Protocols - DHCP lease was terminated

Perhaps you have some of your terminology mixed up.

You can configure a system to have a static IP address,

or you configure a system to be given an IP dynamically -- which is "DHCP".

http://en.wikipedia.org/wiki/Dhcp

"DNS" is Domain Naming Services, and is for routing your signals,

and translating the text words of a location to its actual IP address.

( to the "ones" and "zeroes" that a computer can understand )

http://en.wikipedia.org/wiki/Dns

A DNS server does not give IP addresses to a system;

that's what a DHCP server does for you.

If you haven't set up that Sunfire V445 system with a specific static address,

then it receives its IP address from a DHCP server on your network.

The IP leasing rules on that server can be customized many ways

and that can include such things as a short lease time.

Another possibility is that the DHCP server is configured

to only recognize specific MAC addresses, and yours is an unknown system.

Thus it will refuse to give an IP address to a foreign machine.

That is an example standard Best Practices security,

and since it's a familiar part of Best Practices, that is why there was no other response.

The simple method should be just to sys-unconfig and do not select DHCP as the option when the machine reboots.

The harder method would be to show us the entry in /var/adm/messages or cut and paste from the screen.

Also:

ifconfig -a

and

ls -l /etc/dhcp*

The SC is how the Lights-Out Manager refers to itself when it gives you alerts, etc. To fix this error message:

enter #. when you are operating from the console (whatever you have connected to the Serial/alom port). that should put you in the ALOM control mode.

NOTE: If you haven't used ALOM yet, you will need to set a password for the "admin" account when you attempt to change configuration

A couple of helpful commands in ALOM:

showsc -v(shows current configuration of SC)

setsc netsc_dhcp false(this is the command that will turn off the DHCP alerts)

resetsc(this restarts the SC (no affect on host OS) and is required to apply the change to netsc_dhcp)

console this returns you to the host OS/PROM - wherever you were before you got into SC

If you return to ALOM to check the values, you will be required to log in as admin with the password you created (unless you've created other logins)
