WCF NetMsmqBindingin w7

Question

I'm using NetMsmqBinding to build up service but got sth strange on w7.

if the WCF Client and the service is on the same machine, the client cannot call the service successfully but result in "Access is denied" error (-1072824283, 0xc00e0025). the call can be done if the client is run as administrator.

if the client and the service are on different machines, they can work well (the client don't have to run as administrator).
