bugs, Information_schema appeared as a user in master database

Hi, All
Recently, I was running a script in sql 2000 on window 2000 server like:
declare @.sql nvarchar(4000)
declare @.db sysname ; set @.db = DB_NAME()
declare @.u sysname ; set @.u = QUOTENAME('db_executor')
set @.sql ='select ''grant exec on '' + QUOTENAME(ROUTINE_SCHEMA) + ''.'' +
QUOTENAME(ROUTINE_NAME) + '' TO ' + @.u + ''' FROM
INFORMATION_SCHEMA.ROUTINES ' +
'WHERE OBJECTPROPERTY(OBJECT_ID(ROUTINE_NAME),'
'IsMSShipped'') = 0'
exec master.dbo.xp_execresultset @.sql,@.db
to grant stored procedures execution permition to role, after running the
script, the privilige is grant it to that role, but I got very strange
things happened on sql server.
1. Master database get Information_Shema as a user. dbaccess "via group
membership"
2.Master database got system_function_schema as a user , dbaccess "via group
membership"
3.guest user show in every database in the instance, dbaccess "via group
membership"
if I delete guest account, show me message "the user is not in
database", sp_helpuser did not show guest user, enterprice manager show it
as a user.
4. run sp_grantdbaccess guest. the guest get permitted to use database. I
delete it successful, however, a couple minutes later, it appears in the db
as dbaccess via group membership.
it is really painful for me. could anyone give me a hint to fix the problem?
any help is appreciated.
Thanks
YifeiHi
You may want to try
set @.sql ='select ''grant exec on '' + QUOTENAME(ROUTINE_SCHEMA) + ''.'' +
QUOTENAME(ROUTINE_NAME) + '' TO ' + @.u + ''' FROM ' + @.db +
'.INFORMATION_SCHEMA.ROUTINES ' +
'WHERE OBJECTPROPERTY(OBJECT_ID(ROUTINE_NAME),'
'IsMSShipped'') = 0'
Although if that gives you thre right view you may get nothing back as the
OBJECT_ID function could cause problems, you may therefore want to resort to
using sysobjects.

Thank you for replay,
I think the issue relate to sql 2005, because from em on the server, the
information_shema does not show as user, from em installed sql2005,
information_shema shows as user. Same as another machine that installed sql
2005 and does not run the script.
The reason because I did not check the user until I run the script and have
to check it and find the problem.
Thanks

manager to look at a SQL 2000 database there is no division between
system and user views. If you used a cursor instead of using the
undocumented xp_execresultset this should work.

You are right, what I want to say that sql 2005 caused the information_shema
as a user in master db. it is nothing wrong with running script.
Thanks

In SQL 2005 you need to be more aware of the difference between a schema and
a user. I think Kalen wrote about this some time ago in SQL Server magazine,
but I can't put my hands on this, but you may want to read
