I am trying to find a vbscript that will backup and clear event logs on remote computers. What I am wondering is, can the strComputer function call the contents of a text file that say, has all the computers listed in it and then backup and clear the event logs for said computers?

I found the script from Microsoft that allows one to backup and clear the event logs on a single computer, but being new to this I am not sure where to go next.

This is the script that Microsoft and others have posted for backing up and clearing event logs. I have coupled this with dumpel.exe and have successfully parsed the security logs for the events I was intersted in, then backed up and cleared the logs.

# Begin script 

dtmThisDay = Day(Now)
dtmThisMonth = Month(Now)
dtmThisYear = Year(Now)
strBackupName = dtmThisYear & "_" & dtmThisMonth & "_" & dtmThisDay
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
 & "{impersonationLevel=impersonate,(Backup,Security)}!\\" & _
 strComputer & "\root\cimv2")
Set colLogFiles = objWMIService.ExecQuery _
 ("SELECT * FROM Win32_NTEventLogFile WHERE LogFileName='Security'")
For Each objLogfile in colLogFiles
 objLogFile.BackupEventLog("c:\scripts\" & strBackupName & _
"_Security.evt")
 objLogFile.ClearEventLog()
Next

# End Script 

Any help would be great!

Hi Jeff,

The WMI moniker string (the argument to the GetObject function in your code) only connects to a single computer. However, here are two options:

1. Use the Cmd.exe For command to parse the text file and execute the WSH script for each line in the text file (simpler), or
2. Extend the script to use the FileSystemObject objects and methods to read the text file from within the WSH script (more complex).

For a quick-and-dirty solution, #1 is simpler. For example:

@echo off
setlocal enableextensions
for /f %%p in ('type Computers.txt') do cscript MyScript.vbs %%p
endlocal

The above script echoes each line of the file Computers.txt and passes it as an argument to MyScript.vbs (your WMI script, above).

Solution #2 is beyond the scope of a short forum reply, but there are numerous examples in past articles of how to open, read, and close text files from a WSH script. 

HTH,

Bill
