I was able to connect to database using Enterprise Manager, TOAD and SQLPLUS. At the moment I can only connect using SQLPLUS and I beleive it happened after I changed my computer name. So I changed back my PC name back to orginal name still it's not working.

The error is

ORA-12545: Connect failed because target host or object does not exist.

Pasted below  is my  tnsnames.ora file content

Any help is highly appreciable
