2010 EMS help does not return -examples results

I have been using Exchange 2010 EMS regularly, and have learned to rely on the 'get-help' or 'help' command. Within the last couple of days when I execute a 'get-help command -examples' or 'help command -examples' , I do not get any results. I receive no errors, and I have included an example. If I try this on a different machine, it works fine.

********* EXAMPLE START

********* EXAMPLE END

Ideas?

Thx, Kevin
