Translate get-spuser SID from different domain to username

Question

Get-SPuser turned up
contoso2\S-1-3-12-12451234567-1234567890-1234567-1434
How can I translate this into a user name/identity?
Server I'm working from is on contoso1. There is a trust. Tracked down name of contoso2 server to dcserver.contoso2.com.
Tried
Get-Aduser 'S-1-3-12-12451234567-1234567890-1234567-1434' -Server 'dcserver.contoso2.com'
But got
"Ether the target name is incorrect or the server has rejected the client credentials.
Thanks

If the account still exists, you can use Psgetsid.

Answer 2

Hi @sco gordo ，

As far as I know, when we run the command Get-SPUser, it should return the display name of the user. What's the display name of that user? Does it also show the sid?

Besides, if get-aduser not works, could it be a group in contoso2 server? You could try the command get-adgroup 'S-1-3-12-12451234567-1234567890-1234567-1434'. Maybe it would work for you.
