之前因为从VFP数据库中把数据导入到SQL SERVER2000中，用DTS做了发布与复制数据库'distribution' ，现在要把它删除，当在企业管理器中执行删除时，提示下面的错误：
Error 3724: cannot drop the database 'distribution' because it is being used for replication.
解决方法：
一、首先要备份 master 数据库，在查询分析器选择 master 数据库下操作：
sp_configure 'allow updates',1
reconfigure with override
go
update master..sysdatabases set category = 0 where name='distribution'
delete the distribution database
执行了上面的命令，就可以在企业管理器中删除'distribution'数据库了。
二、方法讨论：
1、如果你只执行这条命令：update master..sysdatabases set category = 0 where name='distribution'
会出现错误：Ad hoc updates to system catalogs are not enabled. The system administrator
must reconfigure SQL Server to allow this.
所以你在必须先执行：
sp_configure 'allow updates',1
reconfigure with override
go
这条命令允许更新，上面的错误才能解决。
2、也可以移除，自己翻译一下 ^_^： Make sure that you did not enable this database for replication by using the sp_helpreplicationdboption system stored procedure. Do not enable the database for replication. If it is enabled for replication, run the sp_removedbreplication stored procedure to disable replication.
IMPORTANT: Running sp_removedbreplication on a database removes all replication objects from the database. Therefore, all publications and subscriptions in the database are removed. Only members of the sysadmin fixed server role can run the sp_removedbreplication stored procedure. For more information about the sp_removedbreplication stored procedure, see the "sp_removedbreplication, Transact-SQL Reference" topic in SQL Server Books Online.
To run the sp_removedbreplication stored procedure, use the following code in which you replace dbname with the name of your database:
执行命令： sp_removedbreplication 'distribution'
