Fix “Access is denied” issue while installing Sql Server 2008 R2

While installing several machine with Sql Server 2008 R2, I encounter the same problem: “Access is denied”.

Apparently this error is related to the account privilege.

Here’s the steps to fix this issue:

1. Log on to the computer as a user who has administrative credentials.
2. Click Start, click Run, type Control admintools, and then click OK.
3. Double-click Local Security Policy.
4. In the Local Security Settings dialog box, click Local Policies, double-click User Rights Assignment, and then double-click Backup Files and Directories.
5. In the Backup Files and Directories Properties dialog box, click Add User or Group.
6. In the Debug Programs Properties dialog box, click Add User or Group.
7. In the Manage auditing and security log Properties dialog box, click Add User or Group.
8. In the Select User or Groups dialog box, type the user account that is being used for setup, and then click OK two times for steps #5, #6 and #7.
9. On the File menu, click Exit to close the Local Security Settings dialog box.

Hope it helps
