Network adapter could not establish connection

Question

I get this error on WLS 6.1 SP2 and WLI 2.1 SP1. This is the scenario. I have
two instances of Weblogic installed on the machine. I first start oracle then,
I bring up the first server run an application and then shutdown the server.
When I try to start the second server, I get this error when the server tries
to make an Oracle database connection.
