    The Network Adapter could not establish the connection  - 17002

      Hi,

       

      this issue has been discussed already but none of the solutions or circumstances seem to be similar to mine.

       

      I have W 7 64bit, SQL Developer 3.2.20.09 and jdk1.7.0_40.

       

      I can connect to "Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production"

      but I cannot get any connection to "Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production" and get the aformentioned error message.

       

      It's not an connectivity issue as I can connect to the database from a different application running on my W7 machine or from SQLDeveloper on my XP machine.

       

      My Oracle Client seems to be "SQL*Plus: Release 11.2.0.3.0 Production".

       

      Any ideas or suggestions?

       

      Many thanks, Rob
