Windows Server - grant the Logon as a batch job privilege

Question: How do I grant the Logon as a batch job privilege to my user account?
Answer: On Windows, this privilege is granted through the Local or Domain Security Policy. To do this using the Local Security Policy, follow these steps.

1. In the Control Panel, open Administrative Tools, then Local Security Policy.
2. Beneath Security Settings, open Local Policies and highlight User Rights Assignment.
3. Locate Log on as a batch job. Open the properties and add any users that need this right.
4. When finished, save your changes and close the Local Security Settings window.

Your changes should take effect immediately. To make changes to the Domain Security Policy, on a domain controller, use the Domain Security Policy utility in the Control Panel.

Windows issues

Windows Keep Check Disk at startup

"fsutil dirty query d: ". This queries the drive, and more than likely it will tell you that it is dirty.

"CHKNTFS /X D:". The X tells Windows to NOT check that particular drive on the next reboot. At this time, manually reboot your computer, it should not do a Chkdsk and take you directly to Windows.

Once Windows has fully loaded, bring up another CMD prompt and type and now you want to do a Chkdsk manually by typing "Chkdsk /f /r d:".
This should take you through 5 stages of the scan and will unset that dirty bit.

Finally, type "fsutil dirty query d:" and Windows will confirm that the dirty bit is not set on that drive.
