LogonUserW Logon failure: the user has not been granted the requested logon type at this computer

Error

[XXX][error] [CM-SBS Exchange BackupSet (1417735865455)]
[XXX] Error uploading data. Reason = ‘[WindowsUtil:createProcessAsUserN] Failed to LogonUserW for wcDomain=’DOMAIN’ username=’cmadmin’. (1385) Logon failure: the user has not been granted the requested logon type at this computer.

Cause

The user defined in “domain authentication for windows” does not have appropriate access privileges (either local or group policy) needed to start the backup.

Resolution

  1. Check the credentials defined in the “windows domain authentication” settings
  2. Check local and group policies to ensure that the user has administrator privileges
  3. As a last resort – set the “Log On” settings for the backup scheduler system service to logon as a valid user, rather than the “Local System” account.
