I have many power shell scripts on my servers that report to me status I have Exchange 2016 CU10 DAG setup 2 NODES My scripts all point to NODE 1 but when I take down NODE 1 for maintenance No email is received. thru NODE 2 I changed the script to point to NODE 2 and it works great. How can I automatically switch from NODE 1 to NODE 2? Here is a sample script I use. $Server = hostname $Subject = “$Server Delete VSS Report” $Body = “Open attachment for Delete VSS Report” $From = “[no-reply@mynet.com](mailto:no-reply@mynet.com)” $To = “[systems-alert@mynet.com](mailto:systems-alert@mynet.com)” $LogFolder = “c:\util\logs” $LogFile = “vss.txt” remove-item -path $LogFolder$LogFile -Force vssadmin list shadows \>\>$LogFolder$LogFile vssadmin delete shadows /all /quiet \>\>$LogFolder$LogFile vssadmin list shadows \>\>$LogFolder$LogFile $PSEmailServer = “[SERV021-N1.MYNET.COM](http://SERV021-N1.MYNET.COM)” Send-MailMessage -From $From -To $To -Subject $Subject -Body $Body -smtpserver $PSEmailServer -attachment “$LogFolder$LogFile” [SERV021-N2.MYNET.COM](http://SERV021-N2.MYNET.COM) IS NODE 2 Thank you Tom     ---

You could detect the availability of the two servers and make a decision which to use for Hostname ``` $Mailservers = @("HOST1","HOST2") if (Test-Connection -ComputerName $Mailservers[0] -Count 1 -Quiet) { # first Server is UP $Nailserver = $Mailservers[0] } elseif (Test-Connection -ComputerName $Mailservers[1] -Count 1 -Quiet) { # second server is UP $Mailserver = $Mailservers[1] } else { Write-Error "No Mailservers Available" } ``` ---

Schlauge, Thanks for the fast reply. That’s a good start.   I should have mentioned that both server are up and running. When I meant it was in Maint Mode it is applying upgrades to Exchange. I need a check that will detect the Exchange Server is in Maint mode. Thoughts?   ---

How do you determine the state where you would consider the Exchange server in MaintMode? Are you running another script, externally, tp place the Exchange server into Maintenance. That should point you in the right direction. I’m not an Exchange guy, but I found this with a quick search. [Get-ServerComponentState](https://docs.microsoft.com/en-us/powershell/module/exchange/server-health-and-performance/get-servercomponentstate?view=exchange-ps) or [Exchange Maintenance Mode](http://ehloexchange.com/exchange-maintenance-mode/) ---

You can try PSRemoting to get the state of the HubTrasnport component. The overall logic is the same: \

Schlauge

Your code below looks good can we use this

Test-NetConnection -ComputerName SERV021-N1 -port 25

Output is in my last posting above

This will test if port 25 is available  
$Mailservers = @(“HOST1”,“HOST2”)

if (Test-Connection -ComputerName $Mailservers[0] -Count 1 -Quiet) {

# first Server is UP

$Nailserver = $Mailservers[0]

}

elseif (Test-Connection -ComputerName $Mailservers[1] -Count 1 -Quiet) {

# second server is UP

$Mailserver = $Mailservers[1]

} else {

Write-Error “No Mailservers Available”

}  
 

 

TcpTestSucceeded : False when port is not available

I would do like below.

Create a function to send mail, then

```
$Mailservers = @("HOST1","HOST2")
$Mailserver = ''
$Mailservers | ForEach-Object -Process {
   if (Test-Connection -ComputerName $_ -Count 1 -Quiet) {
     $Mailserver = $_
   }
}
if($Null -ne $Mailserver){
   # Call send mail function here
}
else{
   # Throw here
}

#Or 

$Mailserver = Test-Connection -ComputerName $Mailservers -Count 1 -ErrorAction SilentlyContinue
if($Null -ne $Mailserver){
   # Call send mail function here
   $ActiveServer = ($Mailserver|Get-Random)
}
else{
   # Throw here using $Error
}
```

It would be great if you update the post by formatting the code using code posting tags , this makes other to easily understand your code, below link will help you.

Guys

 

[PRE]Invoke-Command -ComputerName $Mailservers[0] -FilePath c:\Util\get-exchangestatus.ps1 [/PRE]

I created the script get-exchangestatus.ps1 on my exchange servers in the folder c:\util

but when I run the command above it returns command not found.

So I placed the script on my local c drive in the same folder it ran but had this error

[PRE]Active Directory operation failed on . The supplied credential for ‘MYNET\myaccount’ is invalid.

   
+ CategoryInfo : NotSpecified: (🙂 , ADInvalidCredentialException  
   
+ FullyQualifiedErrorId : [Server=SERV021-N1,RequestId=2b810f62-fd8c-4b97-91cb-69958d5d7ba0,TimeStamp=9/30/2018 1:44:28 PM] [FailureCategory=Cmdlet-ADInvalidCredentialException] 3A548CBE  
   
+ PSComputerName : [SERV021-N1.mynet.com](http://SERV021-N1.mynet.com)  
[/PRE]

So how can I run the script on the exchange server?

I have many servers that need to run this script

I thought the invoke-command would work

 

Thoughts?

Tom,

Start with Enter-PSSession from a Powershell prompt

[PRE]  
Enter-PSSEssion -ComputerName SERV021-N1  
[/PRE]

If you can connect to connect to the remote server, then run the Get-ServerComponentState

[PRE]  
Get-ServerComponentState -Component HubTransport  
[/PRE]

IF this works, then you can expand that to the previous script I provided. It looks like my last, got garbled somehow…

[PRE]  
$Mailservers = @(“SERV021-N1”,“SERV021-N2”)  
$MailSvrStatus = Invoke-Command -ComputerName $mailServers -ScriptBlock {  
Enter-PSSEssion -ComputerName SERV021-N1

if ( {  
# first Server is UP  
$Nailserver = $Mailservers[0]  
}  
elseif (Test-Connection -ComputerName $Mailservers[1] -Count 1 -Quiet) {  
# second server is UP  
$Mailserver = $Mailservers[1]  
} else {  
Write-Error “No Mailservers Available”  
}

Tom,

Break this down into little chunks…  
…Can you get the Mail Server’s Maint Status from the server running the script…

Try starting with Enter-PSSession from a PowerShell prompt

```
Enter-PSSEssion -ComputerName SERV021-N1
```

If you can connect to connect to the remote server, then run the Get-ServerComponentState from within the session

```
Get-ServerComponentState -Component HubTransport
```

IF all this works, then you can expand that to the previous script I provided. It looks like my last, got garbled somehow…

```
$Mailservers = @("SERV021-N1","SERV021-N2")
$mailServerStatus = Invoke-Command -ComputerName $mailServers -ScriptBlock { Get-ServerComponentState -Component HubTransport }

if ( $mailServerStatus[0].State -eq "Active" ) {
# first Server is UP
$Nailserver = $Mailservers[0].Server
}
elseif ($mailServerStatus[1].State -eq "Active") {
# second server is UP
$Mailserver = $Mailservers[1].Server
} else {
Write-Error "No Mailservers Available"
}
```

if you can’t get a PSSession to get the data you are looking for… then you’ll need some other method to get the state of Maintenance Mode.

I hope this helps…

Perhaps a better way to tell if the Exchange server is ready, is to utilize the Test-ServiceHealth cmdlet. That is provided you are running the script from the Exchange management shell where this cmdlet is available.

It will check if all required services are running on said Exchange server. And if they are running, you will be OK to send mail through it.

Simply edit to your original sample script, replace the following line:

 

```
$PSEmailServer = "SERV021-N1.MYNET.COM"
```

 

with an if statement that checks if services are running, then sets your PSEmailServer variable with the server name:

 

```
if (Test-ServiceHealth -Server SERV021-N1.MYNET.COM | ? {$_.RequiredServicesRunning -eq $False}) 
	{$PSEmailServer = "SERV021-N2.MYNET.COM"} 
	else {$PSEmailServer = "SERV021-N1.MYNET.COM"}
```

I Like Cheese

Nice command but I still need the exchange powershell modules loaded.

I am trying this

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://$MailServers[0]/PowerShell/ -Authentication Kerberos -Credential $cred  
Import-PSSession $Session -DisableNameChecking  
$mailServerStatus = Get-ServerComponentState -Identity $EMailservers[0] -Component HubTransport
