I had the same issue. My password was having @ in between so oracle couldn't find that in tnsnames.ora. When I gave the password in double quotes like connect system/"password"@XE, it got connected.

Asadul Islam : 1)check your oracle service name which is defined in tns.ora 2) check your oracle service is running or not. If not resolved, please show me command you are firing.
