Meterpreter commands do not function after successful exploit about armitage HOT 4 CLOSED

Disregard.
I did not realize I needed to "wait" until I received UID information before 
proceeding.  All is well.

Good job on Armitage ... I really enjoy using this graphical tool when teaching 
new security students.

I *greatly* enjoy the fact that you're using it to teach new students. Thanks 
for following up and closing the loop here. -- Raphael

What do you mean "wait" until you receive UID? I've successfully exploited a 
target, and after 2 minutes, the help command still does not bring back 
relevant commands.

@alton.jx - I'm referring to the information displayed below the compromised 
target. If you successfully exploit a Windows system, you will see something 
like NT AUTHORITY @ SOMESYSTEM below the IP address. When you see this, you're 
done waiting.

This should happen pretty quickly (a few seconds). If it doesn't happen, 
contrary to popular belief, waiting won't solve this problem. It's kind of the 
hacker equivalent of speaking english louder and louder hoping a non-native 
speaker will understand or throwing the same SMB exploit against a Windows 7 
host hoping that.... this time, maybe--access will come.

If you can't enter *any* commands:

It sounds like your session becomes established but it never finishes syncing. 
Try rebooting your target. Remember, you're likely exploiting a memory 
corruption bug. If the memory is already corrupted or in some odd state--your 
attack (or post-exploitation kit) won't work.

If *some* commands are missing but a few basic things are present:

Then it sounds like Meterpreter didn't load the stdapi and priv modules. Type: 
use priv and use stdapi to load these by hand. These are DLLs that Meterpreter 
injects into memory on establishing a session (usually). Armitage is smart 
enough, that if you try to do something through a menu and it doesn't work, 
it'll issue these use commands for you. (The command may be load now, I think 
this changed recently in Metasploit)

So, that long explanation is what I mean by "wait" until you receive a UID.
