.After you create the
sp_help_revlogin stored procedure, run the
sp_help_revlogin procedure from Query Analyzer on the source server. The
sp_help_revlogin stored procedure can be used on both SQL Server 7.0 and SQL
Server 2000. The output of the
sp_help_revlogin stored procedure is login scripts that create logins with the
original SID and password. Save the output, and then paste and run it in Query
Analyzer on the destination SQL Server. For example:
[sql]
EXEC master..sp_help_revlogin
[/sql]
