I have a DLL that pings a host via ICMP and raw sockets.  It works fine when
I am logged in as an admin, but it does not work for a normal user.  I get
this error:

An attempt was made to access a socket in a way forbidden by its access
permissions

I have found out that this is by design, and can be fixed by editing the
registry to stop the security checks on the RAW sockets.  I don't like that,
as it opens up other security risks on that PC.

I have tried to set the DLL to have FullTrust permissions, but that does not
seem to be working, either.  If I set up FullTrust properly, should that
override that particular Permission problem?  I may not have it set up right,
since I have not done anything with setting up security in that manner
before.  

If there is another option, I am all ears, but I need that ping utility to
work, as it does a speed test to see how fast the connection to a particular
host is.  If there is another way to do a speed test, I am also all ears.  As
long as the same problem does not come up for it as well.

I look forward to your replies!
