Hello,
If you continue to see the problem as mentioned after restarting netowker 
and GST services & is not corrected after waiting a few minutes, to date i 
only know one solution that could correct the problem is re-installing NMC 
( rename existing NMC directories).
You may lose the existing reports, dB etc, if you need them  you might 
have to re-import it  or re-use it with different install of NMC on a 
different machine ( you will need to work out the feasibility of such a 
solution and or issues with it).
Anyless someone has come up with better solution.
Thanks
