Hello, Can anybody help me with this script. I want 20 DC to have a every 3 hours a backup of the security eventlog, but on a DomainController it doesn`t work, only the Application and System eventlog will work. The script give me No errors. I`m member of the administrators and domain admins group. Here is the script. strComputer = "." Set objWMIService = GetObject("winmgmts:" _ & "{impersonationLevel=impersonate,(Backup)}!\\" & strComputer & "\root\cimv2") Set colLogFiles = objWMIService.ExecQuery _ ("Select * from Win32_NTEventLogFile where LogFileName='Security'") For Each objLogfile in colLogFiles errBackupLog = objLogFile.BackupEventLog("c:\temp\Security.evt") If errBackupLog <> 0 Then Wscript.Echo "The Application event log could not be backed up." End If Next Floyd
