Ora-12154 after creation of second database

Question

DB 10g ver 10.1.0.2.0
OS Windows server 2003 32bit +sp1
Summary:
Due to the addition of extra storage to the server I decided to rebuild from scratch, and all was working correctly until I came to create a second database on the server, once this is created I get ORA-12154 errors at logon for both databases.
Full:
Installation of Windows and Oracle are fine, creation of the first database also works correctly and connection is without problems e.g sqlplus user/pass@database1 allows me to logon.
On creation of the second database the same command: sqlplus user/pass@database1 or sqlplus user/pass@database2 gives me an ORA-12154 error.
If in the command prompt window I set ORACLE_SID=database1 then try sqlplus user/pass it connects without problems, the same for database2, although sqlplus user/pass@database1 still fails.
I have checked tnsnames.ora, all looks fine, I used the net configuration assistant to generate the entries and used the connection test to verfiy all was ok, both connection tests worked fine.
I can tnsping both database1 and database2 and lsnrctl status shows
Service "database1" has 1 instance(s).
Instance "database1", status READY, has 1 handler(s) for this service...
Service "database1XDB" has 1 instance(s).
Instance "database1", status READY, has 1 handler(s) for this service...
Service "database2" has 1 instance(s).
Instance "database2", status READY, has 1 handler(s) for this service...
Service "database2XDB" has 1 instance(s).
Instance "database2", status READY, has 1 handler(s) for this service...
I have searched through back posts and the web and as yet have not been able to find how to resolve this. Any pointers or ideas as to why I cannot use the sqlplus user/pass@database to connect?
TIA
Will

Hi,
Thanks for the quick reply, I created the listener using the net configuration assistant, I assumed this would add all necessary configuration entries?
I have added an extra section as suggested to the listener.ora, it now reads
# listener.ora Network Configuration File: c:\oracle\product\10.1.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
     (GLOBAL_DBNAME = dm)
     (ORACLE_HOME = c:\oracle\product\10.1.0\db_1)
     (SID_NAME = dm)
    (SID_DESC =
     (GLOBAL_DBNAME = medline)
     (ORACLE_HOME = c:\oracle\product\10.1.0\db_1)
     (SID_NAME = medline)
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = c:\oracle\product\10.1.0\db_1)
      (PROGRAM = extproc)
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = well-mccarthy02)(PORT = 1521))
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
  )Is this correct, I have bounced the listener and still get ora-12154 errors on connection.
running lsnrctl services gives:
