Moving the master and Resource Databases.
The Resource database depends on the location of the master database. The Resource data and log files must reside together and must be in the same location as the master data file (master.mdf). Therefore, if you move the master database, you must also move the Resource database to the same location as the master data file. Do not put the Resource database in either compressed or encrypted NTFS file system folders. Doing so will hinder performance and prevent upgrades.

To move the master and Resource databases, follow these steps.

1. Open Sqlserver Management Studio, Click on New Query and notedown the properties of master database. Please do not close this window until you  finish the activity.

SELECT name, physical_name AS CurrentLocation, state_desc
FROM sys.master_files
WHERE database_id = DB_ID(‘master’)

2. From the Start menu, point to All Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server  Configuration Manager.
3. In the SQL Server 2005 Services node, right-click the instance of SQL Server (for example, SQL Server (MSSQLSERVER)) and choose Properties.
4. In the SQL Server (instance_name) Properties dialog box, click the Advanced tab.
5. Edit the Startup Parameters values to point to the planned location for the master database data and log files, and click OK. Moving the error  log file is optional.

The parameter value for the data file must follow the -d parameter and the value for the log file must follow the -l parameter. The following example shows the parameter values for the default location of the master data and log files.

-dC:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\master.mdf;-eC:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG\ERRORLOG;-lC:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\mastlog.ldf

If the planned relocation for the master data and log files is E:\SQLData, the parameter values would be changed as follows:

-dE:\SQLData\master.mdf;-eC:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG\ERRORLOG;-lE:\SQLData\mastlog.ldf

6. Stop the instance of SQL Server by right-clicking the instance name and choosing Stop.
7. Move the master.mdf and mastlog.ldf files to the new location.
8. Start the instance of SQL Server in master-only recovery mode(Single user mode) by entering one of the following commands at the command  prompt. The parameters specified in these commands are case sensitive. The commands fail when the parameters are not specified as shown.
9. Open command prompt and type the below commands.

 1. For the default (MSSQLSERVER) instance, run the following command.
  NET START MSSQLSERVER /f /T3608
 2. For a named instance, run the following command.
  NET START MSSQL$instancename /f /T3608

10. Using sqlcmd commands or SQL Server Management Studio, run the following statements. Change the FILENAME path to match the new location of the  master data file. Do not change the name of the database or the file names.

ALTER DATABASE mssqlsystemresource
    MODIFY FILE (NAME=data, FILENAME= ‘D:\SqlData\mssqlsystemresource.mdf’);
GO
ALTER DATABASE mssqlsystemresource
    MODIFY FILE (NAME=log, FILENAME= ‘ D:\SqlData\mssqlsystemresource.ldf’);

11. Open command prompt and type the below command to stop sqlserver

 NET STOP MSSQLSERVER

12. Move the mssqlsystemresource.mdf and mssqlsystemresource.ldf files to the new location.
13. Start the sqlserver again in single user mode once you finished moving the files.
14. Open command prompt and type the below command to stop sqlserver

 NET START MSSQLSERVER /f /T3608

15. Set the Resource database to read-only by running the following statement in SSMS.
 
ALTER DATABASE mssqlsystemresource SET READ_ONLY;

16. Exit the sqlcmd utility or SQL Server Management Studio.
17. Stop the instance of SQL Server.
18. Restart the instance of SQL Server.
19. Verify the file change for the master database by running the following query. The Resource database metadata cannot be viewed by using the  system catalog views or system tables.

SELECT name, physical_name AS CurrentLocation, state_desc
FROM sys.master_files
WHERE database_id = DB_ID(‘master’)
