I am using TOAD 8.6.1 to connect to an oracle database.  I have already done a tnsping and everything came back ok.  But when i try to connect to this particular schema i get 'ORA-12571: TNS:packet writer failure' , when i hit ok, it allows me to query the database but not use the schema browser (to see functions, procedures, etc).  I have verified my TNSNAME.ORA file is ok (verified by the tnsping).  Any ideas why i may be getting this or how it can be fixed?
