Since you are getting a "RPC Error" I would suggest you
use the "DCOMbobulator" at
www.grc.com/dcom to see
if this might stop the RPC Error; sometimes it works,
sometimes it doesn't . You may also want to try the other
2 "Musketeers" while on the grc site and this site has
the recommended "Shields Up" firewall "test" .
You might want to check the dosaje "thread" here for
possible solution(s) !?
