Exchange 2010 Correlation Engine

Creating overrides for the Exchange Correlation engine is not easy. Here is a link that shows you how to correctly change the monitors or rules.

Often the rules or monitors are using numerical values for severity and priority. Here is an article that shows what the numerical values are.

Reset Local Administrator Password(s)

Here are two PowerShell scripts to reset the local administrator password on multiple machines.  The first one seaches an OU with a filter on objectClass=Computer and prompts for a new password.  The second script you use a text file imported with computer names which the script reads from.  Either way works, I prefer the first.

## This variable creates the LDAP connection to Servers, you must enter in the correct DN name of the OU you will be using.
$objDomain = [adsi] (“LDAP://OU=Servers,OU=OU,dc=domain,dc=local”)

$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = $objDomain
$objSearcher.PageSize = 1000
$objSearcher.Filter = ‘(objectClass=Computer)’
#$objsearch.propertiestoload.add(“name”)
$colResults = $objSearcher.FindAll()

$password = read-host “Please type in the new password.”

$erroractionpreference = “SilentlyContinue”
foreach ($Computer in $colResults) {   
    $ServerName = $($Computer.properties.name).ToUpper()       
    $ping = new-object System.Net.NetworkInformation.Ping   
    $Reply = $ping.send($ServerName)       

        if($Reply.status -eq “success”) {       
            Write-Host “$ServerName is online”       
            $Admin=[adsi](“WinNT://” + $ServerName + “/administrator, user”)       
            $Admin.PSBase.Invoke(“SetPassword”, $password)               

            # Verify password was just changed       
            $PasswordAge = $Admin.PasswordAge               
            If($PasswordAge -ne $null) {                       
            Write-Host “$ServerName password change SUCCEEDED”               
            } Else {           
                Write-Host “$ServerName password change FAILED”               
            }   
            } Else {       
                Write-Host “$ServerName is not online – skipping”       
            }
        }

 

#This script will change the local adminstrator password for every machine in serverlist.txt
#Only if the server is online via ping request

$erroractionpreference = “SilentlyContinue”

##for <directorylocal> type in the correct location of the serverlist.txt
foreach ($Computer in get-content <directorylocal>\serverlist.txt) {   
    $ServerName = $Computer.ToUpper()       
    $ping = new-object System.Net.NetworkInformation.Ping   
    $Reply = $ping.send($Computer)       

        if($Reply.status -eq “success”) {       
            Write-Host “$ServerName is online”       
            $Admin=[adsi](“WinNT://” + $Computer + “/administrator, user”)     

##replace –-password—with the actual password  
     $Admin.PSBase.Invoke(“SetPassword”, “–password–”)               

            # Verify password was just changed       
            $PasswordAge = $Admin.PasswordAge               
            If($PasswordAge -ne $null) {                       
            Write-Host “$ServerName password change SUCCEEDED”               
            } Else {           
                Write-Host “$ServerName password change FAILED”               
            }   
            } Else {       
                Write-Host “$ServerName is not online – skipping”       
            }
        }
