Hi,
Go to the Assistant at
on the Atlantic LAN (Give your Laptop 192.0.2.100)
Go through the Client Preparation if not already done.
If you are using Windows XP then just remove your Java from the control panel and download the java from the client preparation.
If using Windows 7 then you will have to add in a virtual machine with XP to do this.
After you are finished the client preparation then log on to the assistant.
After logging on then go to
Base Administration
Unix Base Administration
LAN Cards
Delete the existing IP address there with the big red x
Add in the new IP address using the top white page icon
Ensure you have the subnet netmask correct
and the broadcast address
Then in routes
check the default
add in the local router for your subnet
metric 1 or 2
In firewall add in subnets that need access or individual PC's
When done click on shutdown
and restart the unix
Good Luck
