Multi-Hop Authentication with Powershell

Data Flow:
A -> B -> C

Using the example above....If you try to execute a remote command from computer A against Computer B, if the command requires authentication it will try to communicate with a Domain Controller (Computer C). This authentication attempt will fail because Computer B is not trusted as a delegate to pass credentials by default. To resolve this problem we can enable the Credential Security Service Provider (CredSSP) Authentication.

Steps:
Make sure windows remote administration has already been enabled on computer.
On Computer A, enable this feature as a client:
     - Enable-wsmancredssp -role client -delegatecomputer "*.domain.com"
On Computer B, enable this feature as a server
     - enable-wsmancredssp -role server

Example Code Snippet:
Invoke-Command -authentication credssp -credential "domain\username" -computer "ComputerB" -scriptblock {try
                {import-module lync;
                    Enable-CsUser -Identity <username> -RegistrarPool "lync.domain.com" -SipAddressType EmailAddress  -SipDomain cpex.com}
                    catch{write-host $_.exception}
                }

A command like this(above) will fail without enabling CredSSP. This solution of course requires you to interactively type in the password.
