Description of SQL2005 server error after reloading renaming _mssql2005

The error message is:
The server ' BBB ' was not found in the sys.servers. Please verify that the specified server name is correct. If necessary, execute the stored procedure sp_addlinkedserver to add the server to Sys.servers.
The reason is because the name of the computer changed after installing the system, the original name is "AAA", the new computer name is "BBB"
Workaround:
First step:
Open SQL Server Management Studio and create a new query:
SELECT * FROM Sys.servers
Go
The original computer name can be obtained here. Then record it (copy it)
(For example, the original name is AA)
Step Two:
New query:
sp_dropserver [AAA]
Go
sp_dropserver [BBB]
Go
Here is the original name and now the name are deleted.
Step Three:
New query:
sp_addserver [BBB]
Go
sp_addserver ' BBB ', ' local ', ' DUPLICATE_OK '
Go
Here is the new server name BBB
Fourth Step:
New query:
Sp_serveroption ' BBB ', ' data access ', ' true '
Go
Restarting the server is complete.
