I'm trying to handle and continue from 'fatal errors' in scripts. I know the -EA silentlycontinue doesn't work but keep coming back to using foreach to get around it but solutions http://stackoverflow.com/questions/18845747/suppressing-fatal-error-access-denied I find don't work for me for example and this is an example not what I'm trying to do...

Hits: Finding Exception Types withPowerShell → A Look at Try/Catch inPowerShell Posted on April 4, 2015 by Boe Prox My article here wraps upPowerShell Blogging Week (#PSBlogWeek), which has been a series of articles on Windows PowerShell Advanced Functions. We hope that you have enjoyed this series and hope you will supply https://learn-powershell.net/2015/04/04/a-look-at-trycatch-in-powershell/ us with more ideas so we can continue to provide fun and useful material for you! When working with errors and trying to get a handle on them, you need to use what is available to not only catch http://www.workingsysadmin.com/cheating-to-fix-access-is-denied-error-using-get-wmiobject/ them, but also to determine what the next course of action is after you have caught them. In this article, I am focusing solely on Try/Catch (along with Finally) and how you can use these to perform some essential error handling error handing in your scripts. Let’s break down each of these statements and what they accomplish. Try Try is where you are going to place your code block in that you want to watch for errors that will be handled later on in the script. Know that wherever the error occurs, it will immediately stop at that point and move onto the Catch keyword (assuming that the error is a terminating error). During this you need to ensure that get-wmiobject access is you either have $ErrorActionPreference=’Stop’ so every error that occurs is considered a terminating error (useful when working with outside commands that do not throw terminating errors by default) or you can make use of –ErrorAction ‘Stop’ in a cmdlet to force the cmdlet to throw a terminating error. Note: Did you know that using the Throw keyword says that the error being thrown is a terminating error? Try it in a Try/Catch and see what happens! Here is an action of what be in a Try statement: Try { Write-Verbose "[TRY] Checking for OS" -Verbose $OS = Get-WmiObject -ComputerName RemoteServer -Class Win32_OperatingSystem -ErrorAction Stop Write-Verbose "[TRY] No issues found" -Verbose } Assuming that I can connect to this remote system, I should see the Verbose output afterwards, otherwise based on the ErrorAction of Stop, it will send the execution down to the Catch statement. Catch Here is where the execution of code continues after an error occurs within the Try statement. One of the neat things about using Catch is that you can have multiple Catch statements based on the error type that you want to handle. If you want to take a different action on an Access Denied error, you can specify the System.UnauthorizedAccessExceptiontype and anytime the error record relates to an unauthorized access exception, it will be handled in that statement while all other errors will be handles by the Catch s
wmiThmsRynr I was doing a little work that involved using PowerShell to get a list of printers from several remote print servers. I figured this would be a great job for WMI and I was right. The command I used, looked like this. $printserver = "printserver1.domain.tld" Get-WMIObject -class Win32_Printer -computer $printserver | Select Name,DriverName,PortName | Export-CSV -path 'C:\temp\$printserver.csv' 12 $printserver = "printserver1.domain.tld"Get-WMIObject -class Win32_Printer -computer $printserver | Select Name,DriverName,PortName | Export-CSV -path 'C:\temp\$printserver.csv' I had a list of print servers that I imported into an array and looped through them but this is the important part of the code. I am simply using WMI to get some information about the logical printer objects on a given print server and exporting them to a CSV. How boring! This isn't a very old blog but we usually talk about more complicated things than that. Well things got weird on one print server that we'll simply call PrintServer2. PrintServer2 threw an error instead of working nicely. Get-WMIObject : Access is denied.

I have Domain Admin rights… it's a domain joined server… what do you mean access is denied? Running the command locally on the server worked, I just couldn't do it remotely. There's plenty of literature on trying to fix this error already but I was in a hurry so I tried the next thing that came to mind: cheat a bit and run the command locally on the server… remotely. $printserver = "printserver2.domain.tld" invoke-
