I'm revising a chat application to use named pipes.

I have it working fine from two command lines running as administrator
on both machines. But in production it will be launched from a service
running as "Local System account" (under 'Log On' in the 'properties'
page
of its service). It also have "Allow service to interact with desktop"
checked.

When I invoke the chat program from this service (via 'spawn') I get
ERROR_ACCESS_DENIED (code 5). For completeness I tried command line
invocation from a limited user account and got error 1326 (logon
error).

How do I set the permissions of the named pipe to allow the service to
connect?
I've seen various descriptions of security tokens and ACLs, but
haven't seen a good description of doing this sort of thing.

Thanks much for any guidance whatsoever.
