Dear all,
I couldn't connect to my oracle 8.0.5 server after I changed the IP address from 172.16.x.x to 172.18.x.x. I have to change all my computers in my domain to 172.18.x.x. Everything is working properly after address change, except I couldn't connect to Oracle. I can ping to the server but I couldn't tnsping to it. There is error message in listener.log:

System parameter file is C:\orant\NET80\admin\listener.ora

TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
32-bit Windows Error: 50: Unknown system error


Question: How to fix this problem? What is the proper step of changing address for Oracle server?

Now the listener service dies without giving any clue in the NT's event viewer. I can start it up, but after a few minutes the service will die.

Thanks in advance,
