Removes a server from the list of known remote and linked servers on the local instance of SQL Server.
If you run sp_dropserver on a server that has associated remote and linked server login entries, or is configured as a replication publisher, an error message is returned. To remove all remote and linked server logins for a server when you remove the server, use the droplogins argument.
sp_dropserver cannot be executed inside a user-defined transaction.
The following example removes the remote server ACCOUNTS and all associated remote logins from the local instance of SQL Server.
sp_dropserver 'ACCOUNTS', 'droplogins';
