This is what Oracle says about it:
ORA-12203: TNS:unable to connect to destination

Cause: Invalid address specified or destination is not listening. This error can also occur because of underlying network or network transport problems.

Action: Verify that the net service name you entered was correct. Verify that the ADDRESS portion of the connect descriptor which corresponds to the net service name is correct. Ensure that the destination process (for example the listener) is running at the remote node.

I don't know will you find it helpful or not, but - just being curious - what bad luck made you install Oracle 7 these days? It is quite an old (and desupported) version (as well as 8i). Not that those versions aren't good or something, but - there are newer ones at the market.
