Get-WmiObject to remote computer fails with "rpc server is unavailable" and vice versa "Access denied"

Question

Hi
Still learning PowerShell remoting.
Can access with remoting 2 computers (XPProf/SP3, Workgroup) perfect. Powershell2.0 (running as Administrator).
Using Firewall ZoneAlarm not Windows Firewall (stopped).
But when using Get-WMIObject always run into
"rpc server is unavailable" in one direction and "Access denied" in the other direction.
Searched the forum but didnt find infos.
Switched off Firewalls: Still the same.
So I'm stuck.
Any help is appreciated.

Yo encontré estas recomendaciones que me sirvieron para poder consultar el servidor remoto.

 Allow WMI through Windows firewall
All users (including non-administrators) are able to query/read WMI data on the local computer.
For reading WMI data on a remote server, a connection needs to be made from your management computer (where our monitoring software is installed) to the server that you're monitoring (the target server). If the target server is running Windows Firewall (aka
Internet Connection Firewall) like what is shipped with Windows XP and Windows 2003, then you need to tell it to let remote WMI requests through<sup style="margin:0px;padding:0px;list-style:none;">2</sup>. This can only be done at the
command prompt. Run the following on the target computer if it is running a Windows firewall:
      netsh firewall set service RemoteAdmin enable
Como segunda opcion tambien se puede modificar el group policy y especificar que ips tendran acceso a consultar el WMI remotamente.

Using Group Policy
To enable or disable the Remote administration exception
Open the Group Policy Object Editor snap-in to edit the Group Policy object (GPO) that is used to manage Windows Firewall settings in your organization.
Open Computer Configuration, open Administrative Templates, open Network, open Network Connections, open Windows
Firewall, and then open either Domain Profile or Standard Profile, depending on which profile you want to configure.
In the details pane, double-click Windows Firewall: Allow remote administration exception.
In the Windows Firewall: Allow remote administration exception properties dialog box, on the Settings tab, click Enabled or Disabled.
