Not a MVP (yet...? :P) but will try to help you.
I am afraid that it is not possible without calling some external COM object
from within T-SQL. See the script by Umachandar Jayachandran:
DECLARE @.ServerName varchar( 128 ), @.SQLServer int, @.RetCode int,
@.Instances int, @.Count int, @.NumInstances int, @.Instance varchar(
128 )
EXEC @.RetCode = sp_OACreate 'SQLDMO.SQLServer2', @.SQLServer OUTPUT
IF @.@.ERROR|@.RetCode <> 0 GOTO Error_Handler
EXEC @.RetCode = sp_OAMethod @.SQLServer, 'ListInstalledInstances', @.Instances
OUTPUT, @.ServerName
IF @.@.ERROR|@.RetCode <> 0 GOTO Error_Handler
EXEC @.RetCode = sp_OAGetProperty @.Instances, 'Count', @.NumInstances OUTPUT
IF @.@.ERROR|@.RetCode <> 0 GOTO Error_Handler
SET @.Count = 1
WHILE ( @.Count <= @.NumInstances )
BEGIN
EXEC @.RetCode = sp_OAGetProperty @.Instances, 'Item', @.Instance OUTPUT,
@.Count
IF @.@.ERROR|@.RetCode <> 0 GOTO Error_Handler
SET @.Count = @.Count + 1
PRINT @.Instance
END
IF @.Instances > 0 EXEC sp_OADestroy @.Instances
IF @.SQLServer > 0 EXEC sp_OADestroy @.SQLServer
RETURN
Error_Handler:
IF @.Instances > 0 EXEC sp_DisplayOAErrorInfo @.Instances, @.RetCode
IF @.SQLServer > 0 EXEC sp_DisplayOAErrorInfo @.SQLServer, @.RetCode
IF @.Instances > 0 EXEC sp_OADestroy @.Instances
IF @.SQLServer > 0 EXEC sp_OADestroy @.SQLServer
You can see intances list on a machine by checking the registry key
HKLM\SOFTWARE\Microsoft\Microsoft SQL Server\InstalledInstances.
See "ListSQLSvr.exe - Enumerate SQL Servers" for the non-TSQL approach

article Michas sent to me. Now, I understand how the SQL Server should be
configured via a firewall.
Many thanks again, and have a nice day.
