How to delete and create user remotely on SQL Server 2000
I found a workaround

To change the permissions of the user to where it can't write

EXEC [Server].Database.dbo.sp_droprolemember N'db_owner', N'User'
EXEC [Server].Database.dbo.sp_addrolemember N'db_denydatawriter', N'User'


After I am done, change it back

EXEC [Server].Database.dbo.sp_droprolemember N'db_denydatawriter', N'User'
EXEC [Server].Database.dbo.sp_addrolemember N'db_owner', N'User'


Just tested it in my lab environment and it does the trick. Can't wait to get rid of all of our SQL Server 2000 databases! Just a few more months and we will be rolling 120 servers into one SQL Server 2012
