Remote scripting on Windows Server 2008

If you leave the windows firewall turned on on your Windows Server 2008 boxes, you are not allowed to run script against a remote server.
The windows firewall will block these attemps.

Running in a domain, the fastest way to allow remote script execution, is to create a group policy...
Create a new GPO and drill to:
Computer Configuration -> Policies -> Administrative Templates -> Network -> Network Connections -> Windows Firewall -> Domain Profile
Set "Windows Firewall: Allow inbound remote administration exception" to "Enabled"
- and configure with a specific ip address (if only one machine is allowed for remote scripting)or a subnet (the subnet from where the remote script will be fired).
