Today, with the SQL Server 2008 Attach feature attached a database, a bit of a problem, the prompt error is:

Unable to open physical file "D:\Documents\Dalt\XXXX.mdf" Operating system error 5: ' 5 (Error not found) ' (Microsoft SQL Se Rver:error 5120) ".

MSDN Forum says you need to add a user right to the. mdf,.ldf file, run the following statement to find the name of the permission

1 Declare @sqlser varchar( -)
2 EXECMaster.. Xp_regread@rootkey='HKEY_LOCAL_MACHINE', @key='System\currentcontrolset\services\mssqlserver',
3 @value_name='objectname', @value=@sqlserOUTPUT
4 PRINT 'Account starting SQL Server Service:' +Convert(varchar( -),@sqlser) 

The result on my machine is: Account starting SQL Server Service:localsystem, then right-click the folder containing the. mdf,.ldf file, switch to the security interface, add LocalSystem user. I can never find this user here, as

But here are some users such as: User (Prchaz01210\user), Administrator (Prchaz01210\user), I gave the latter to add Full Control permissions, and then try to attach, did not expect to succeed, I do not know the above statement to find out what information, and so there is time to see.
