Powershelling into remote system fails

Run powershell with your admin account and not your standard account.

Run powershell as administrator as well.

Done and done--same error. When prompted I even used domain admin, which I am one of, but just to check.

Can you use your own account on a machine that is confirmed to be working to achieve what it is you're trying to do?

Running the same version of powershell?

In the same OU as another machine that works?

is your computer in the same groups?

Can you ping said machine without any issue?

If you're on a laptop, have you tried doing it over a network cable rather that wireless to rule out a VLAN issue?

Thanks

Sure, little background: working desktop is Windows 7. My desktop is Windows 10. Both in same OU.
We ran the script from his machine to a different one using his and my credentials, worked fine.
I than ran it on my machine and get this error:
  Checking for and installing available updates
Install-WindowsUpdate : (TARGETSERVER: Unknown failure.

I am running it as admin.

Drop yourself into the local admins on that machine and try again.

Our domain's "Domain Admins" group is in the local admins group on that machine.

I'm wondering if it's not liking the nested group.

the OS on the machine that's working, is it 10 as well?

Thanks
Alex

Nope, Windows 7., so I may have more recent PowerShell components.

Hi,

To make sure that you have all the right on remote machine try access \\myremotepc\c$ by default only admin can do this and if you are able to do that you should be able to access powershell

also try via PowerShell ISE (Run as administrator) you should see an icone a named  Remote PowerShell Tab

I've got no idea at this point, the only thing I can think of is your rights but it works from windows 7.

$Psversiontable on both your destination machine and local machine, see if they are massively out. This is my last guess to be fair.

Not a problem, I appreciate all of your input.

PSRemotingProtocolVersion      2.2

Am I to ascertain that the remote system that says  "PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0}                  "  means I can't use 5.x?

I just tried this process on another Windows 10 machine running the same version of Powershell that I am and it errored out again.

I'm going to try remoting from that machine to the server, just to create another test.

can you run other remote commands on those windows 10 machines?  Also for testing purposes can you disable the domain firewall? (please re enable it after testing)

Sure, domain firewall disabled, same error.  Seems to be choking on this command:
Install-WindowsUpdate -ComputerName $RemoteMachine -AcceptAll -Verbose | ft
($RemoteMachine is the hostname and does get assigned)

Error:
Connecting to remote server *******  failed with the following error message : The
WinRM client cannot process the request.  Default credentials with Negotiate over HTTP can be used only if the target
machine is part of the TrustedHosts list or the Allow implicit credentials for Negotiate option is specified.

The person who normally does this says he doesn't edit a TrustedHosts file, but I ran this anyway from https://www.centrel-solutions.com/media/xiaconfiguration/adminguideweb/PowerShellTrustedHosts.html

To trust any machine, use the following command:
Set-Item WSMan:\localhost\Client\TrustedHosts –Value * -Force

Once I ran that, and removed any blank lines from the file I use to target the correct hosts, no errors.
He may have run that command so he didn't need to keep adding to the TrustedHosts.

Thanks gents....
