I just recently setup a PS Web server for my team to be able to share PS scripts. On two of my scripts that manupliate AD I am getting errors.
I have verified that the AD module is available.
Here is one of the errors
Get-ADComputer : Unable to contact the server. This may be because this server does not exist, it is currently down,
or it does not have the Active Directory Web Services running.
At C:\PSScripts\Create Server LADM Groups.ps1:1 char:19
Thanks in advance.
Are you hosting the scripts in a web service?
Can you run the scripts in a normal PowerShell console from the web server?
Is the web server part of the domain?
Do any other scripts that access AD work?
Not sure I know what you mean by hosting the scripts in a web service.
Yes, I can run all the components of the script from the PS web.
Yes.
No.
Thanks in advance 
Hey there Nathan,
Would it be possible to see the script code? I’ve got a PSWA server in my test environment, so I can test and see if I can duplicate the issue.
Actually, I was able to duplicate it just running Get-ADComputer “%servername%”. A couple of things to check:
Make sure that at least one of your DCs is running Active Directory Web Services. You won’t be able to connect without it.
Use the -Server parameter to specify the DC running ADWS.
Alternatively, you could use PSWA to connect to domain controller (you’ll have to make sure it’s in a PswaAuthorizationRule before you can access it), and execute the script from there.
So I have tried your suggestions and it still fails to run for PSWEB.
Here is a copy of my script that I am trying to execute from PSWEB
