Hi List,
Got Oracle 8.1.6 running on Solaris 7 with W2k clients. When the Clients (this is a clarify client not sqlplus) try to connect, an ORA-12545 Connect failed because target host or object does not exist.
tnsping succeeds, as do client connects from clients on a different subnet, and the IP address, rather than name, of the server is specified in tnsnames.ora.

So maybe it's the firewall? Does anyone know what is required at the network level for successfull Oracle client-server operation? Also, if some of these network facilities are missing, due to firewall problemettes, could that lead to an error 12545?

Tia
