Do you mean "connect sys/@xyz as sysdba"? This command is invalid for me in either server or client. But "connect /@xyz as sysdba" or "connect sys/passwd@xyz as sysdba" works. Pls advice.
LY :

He says hez getting ORA-01031 Insufficient privilege.

Had he jus given conn Sys/@connect string as sysdba, then he wud have got

Usage: CONN[ECT] [logon] [AS {SYSDBA|SYSOPER}]
where ::= [/][@] | /

Probalabaly he forgot to type "PSWD"

Its suerly the problem in SQL * NET. NTS authentiation should be commented.....
