The Same thing happened to us when we upgraded from 7.2.2 to 7.4.2... We
did not stop services or un-install the server software first, just did
an install which upgraded everything in place...
EMC support had me stop / restart the GST service, then look for any
instance of a 'dbsrv9.exe' process and kill it. Once we did that, we
were then able to login via NMC...
These are the type of issues EMC support can usually resolve quickly if
they have seen it before...
