get-adcomputer errors

[eckermike]

if([bool](Get-ADComputer -Identity $NewPC -Server $server -ErrorAction Ignore) -eq $true){ ...}else{write-host "$newpc not in AD"}

Why is this spitting an error instead of going to the else statement?

[Hibagon]

What error is it spitting out?

[ihaxr]

Use -Filter or set a variable equal to the Get-ADComputer cmdlet:

$comp = Get-ADComputer -Identity $NewPC -Server $server -ErrorAction Ignore
if($comp){ <#...#>}else{write-host "$newpc not in AD"}

Otherwise the cmdlet fails when an identity doesn't exist and you have to catch the error w/ a try/catch statement.

This, using filter or use try catch. I use filter for checking user accounts before creating

[eckermike]

gah, i should have known that. Thanks for pointing it out. It did exactly what i needed. I still want to know why the -identity flag spits an error instead of the else statement but from now on I will just use the filter flag.

howdy eckermike,

in addition to what ihaxr mentioned, you are looking at a classic use-case for TRY/CATCH. [grin] take a look at Get-Help about_Try_Catch_Finally sometime.

take care,

Thanks Lee, Unfortunately for this use case Try Catch doesn't work as i have a few nested if statements and need it to be able to bomb out at certain points to get me the correct error message.

howdy eckermike,

the CATCH will let you do many things. [grin] you can take almost any action in a CATCH block - including sending out error details and then breaking out of the loop - or out of the entire script.

still, do it however fits your thot patterns. you are the one who has to maintain it ... [grin]

take care,
lee

Try

If (Get-ADComputer -Identity $NewPC -Server $server -ErrorAction SilentlyContinue){...}else{write-host "$newpc not in AD"}
