Do you know where I can get an answer to the following question:
 
Why do I get the following error: "ORA-12541: TNS:no listener" on my win
2000 professional client when trying to connect using "SQLPLUS
lanier/lanier@cde <mailto:lanier/lanier@cde> ?"
 
1.  The client is a separate box from the server running oracle v8.1.6.
2.  The listener service on the server is running.
3.  Am able to connect using the same string on the server.
4.  The SQLNET trace file reveals the following:
 
niotns: Calling address:
(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=172.18.118.51)(PORT=
1521)))(CONNECT_DATA=(SERVICE_NAME=cde)(CID=(PROGRAM=C:\Oracle\Ora81\bin\SQL
PLUS.EXE)(HOST=CMT01)(USER=jkelton))(SERVER=dedicated)))
