In continuation to my previous post “Check Exchange 2003 vitals with PowerShell”, I also have a code block that you can replace if you want to query all exchange servers in your environment dynamically with script instead of using text file as in the code I posted earlier.

In the code I posted earlier, the following lines read the file servers.txt.

1
2
3

# Read file and store server names in variable
 
$Servers = (Get-Content .\servers.txt)

Replace it with the following, which queries Active Directory for objectclass msExchExchangeServer and returns all servers found.

# Get Exchange Servers from Active Directory
 
function GetExchangeServers()
{
	# Set variables to connect to Active Directory, searching Configuration Naming Context
	$root= New-Object System.DirectoryServices.DirectoryEntry("LDAP://RootDSE")
	$configpartition = [adsi]("LDAP://CN=Microsoft Exchange,CN=Services," + $root.configurationNamingContext)
 
	# Set variables for search criteria
	$search = New-Object System.DirectoryServices.DirectorySearcher($configpartition)
	$search.filter = '(objectclass=msExchExchangeServer)'
 
	# Perform Serach, this will return all Exchange Server objects
	$ExchServer = $search.FindAll()
 
	# Output Name property of each server object stored in ExchServer array
	$ExchServer | foreach {$_.properties.name}
 
	# Comment the line above and uncomment the line below if you want to search specific Exchange servers by name
	# The example filter below will only output servers that have MBX in their name (i.e. MBX01, SRVMBX45 etc.)
	#$ExchServer | foreach {$_.properties.legacyexchangedn -match "MBX"}
}

You will also have to replace the lines:

# Get vitals for each server stored in $Servers array
$Servers | %{getVitals}

with the following:

1
2

# Get vitals for each server stored in $Servers array
GetExchangeServers | %{getVitals}


Comments welcome.
