If you need to management other than using console, you may want to enable inbound rules for Remote Management and Remote Desktop by running these commands in the console.
To enable the Remote Management:
cscript C:\windows\system32\scregedit.wsf /im 1

cscript C:\windows\system32\scregedit.wsf /ar 0
And, you need to enable the remote desktop from the sconfig (the blue console window) also.
