CREATE FILE encountered operating system error 5(error not found)

Hola ! les paso a detallar un inconveniente detectado al tratar de realizar un chequeo de base (DBCC CHECKDB) sobre bases de sistema (master,msdb), previo a tomar un backup de la misma.
Antes de pasar al problema propiamente dicho, les cuento que si realizábamos un BACKUP DATABASE, el mismo lo corria sin inconvenientes.

A continuación se detalla el error:

"DBCC CHECKDB" contra la base de datos "msdb" :

Msg 1823, Level 16, State 2, Line 1
A database snapshot cannot be created because it failed to start.
Msg 5123, Level 16, State 1, Line 1
CREATE FILE encountered operating system error 5(error not found) while attempting to open or create the physical file 'D:\MSSQL.1\MSSQL\DATA\MSDBData.mdf:MSSQL_DBCC16'.
Msg 7928, Level 16, State 1, Line 1
The database snapshot for online checks could not be created. Either the reason is given in a previous error or one of the underlying volumes does not support sparse files or alternate streams. Attempting to get exclusive access to run checks offline.
Msg 5030, Level 16, State 12, Line 1
The database could not be exclusively locked to perform the operation.
Msg 7926, Level 16, State 1, Line 1
Check statement aborted. The database could not be checked as a database snapshot could not be created and the database or table could not be locked. See Books Online for details of when this behavior is expected and what workarounds exist. Also see previous errors for more details.

Explicación:

Al tratar de realizar un snapshot de la base msdb y realizar el chequeo de la misma, no puede, pues arroja "System Error 5" que es 'Access Denied' en la carpeta 'D:\MSSQL.1\MSSQL\DATA\.', Solamente la cuenta SYSTEM y miembros del grupo DOMAD\Administrators tenian permiso de escritura en esa carpeta.

Solución:

Se asigno permisos de escritura sobre el directorio 'D:\MSSQL.1\MSSQL\DATA\' al grupo ' DOMAD\SQLServer2005MSSQLUser$S0001SC3245$MSSQLSERVER', al cual pertenece la cuenta de servicios de SQL.

Abrazo virtual a todos !!!
