Basic Exchange 2010 Health Check PowerShell Script

2017-12-01T12:56:00+00:00 March 30th, 2012|Exchange|

Please see below a handy PowerShell Script which will give you a quick health check on your environment

The PowerShell Script will check the following

  • That all Exchange Databases are Mounted
  • Mapi Connectivity to all databases are working
  • ActiveSync Connectivity to each CAS Server is working
  • OWA Connectivity to each CAS server is working
  • Mailflow to Each Database is working
  • Main CAS Server Ports are open and working
  • IMAP is working
  • POP3 is working
  • All Exchange Services are Started

Please note the test port function in the script is from the following http://gallery.technet.microsoft.com/scriptcenter/97119ed6-6fb2-446d-98d8-32d823867131

The Script will give an output like below

image

At a later date i will be blogging another PS1 script which will give a more verbose output.

Please save the below to a .PS1 file and run from the Exchange Management Shell.

function Test-Port{ 
<#   
.SYNOPSIS   
    Tests port on computer. 
   
.DESCRIPTION 
    Tests port on computer.
    
.PARAMETER computer 
    Name of server to test the port connection on.
     
.PARAMETER port 
    Port to test
      
.PARAMETER tcp 
    Use tcp port
     
.PARAMETER udp 
    Use udp port 
    
.PARAMETER UDPTimeOut
    Sets a timeout for UDP port query. (In milliseconds, Default is 1000) 
     
.PARAMETER TCPTimeOut
    Sets a timeout for TCP port query. (In milliseconds, Default is 1000) 
                 
    To Do: 
        Add capability to run background jobs for each host to shorten the time to scan.         
    
.EXAMPLE   
    Test-Port -computer ‘server’ -port 80 
    Checks port 80 on server ‘server’ to see if it is listening 
   
.EXAMPLE   
    ‘server’ | Test-Port -port 80 
    Checks port 80 on server ‘server’ to see if it is listening
     
.EXAMPLE   
    Test-Port -computer @(“server1″,”server2”) -port 80 
    Checks port 80 on server1 and server2 to see if it is listening 
   
.EXAMPLE
    Test-Port -comp dc1 -port 17 -udp -UDPtimeout 10000
   
    Server   : dc1
    Port     : 17
    TypePort : UDP
    Open     : True 
        
    Description
    ———–
    Queries port 17 (qotd) on the UDP port and returns whether port is open or not
      
.EXAMPLE   
    @(“server1″,”server2″) | Test-Port -port 80 
    Checks port 80 on server1 and server2 to see if it is listening 
     
.EXAMPLE   
    (Get-Content hosts.txt) | Test-Port -port 80 
    Checks port 80 on servers in host file to see if it is listening
    
.EXAMPLE   
    Test-Port -computer (Get-Content hosts.txt) -port 80 
    Checks port 80 on servers in host file to see if it is listening
       
.EXAMPLE   
    Test-Port -computer (Get-Content hosts.txt) -port @(1..59) 
    Checks a range of ports from 1-59 on all servers in the hosts.txt file
