The problem is the driver what IDE a you using ?
are these two words "dss w2k01"?

This is not a driver problem, this is either because your hostname or port number are wrong, or the TNS Listener isn't running on the db box.

Can you ping that server?
Can you connect to that oracle instance using SQL*Plus?
