Hi Shawn,

here are the test results with net send:
--------------------------------------------
C:\>net send dh01094\h0109401 "Test"
The syntax of this command is:
NET SEND
{name | * | /DOMAIN[:name] | /USERS} message

C:\>net send h0109401 "Test"
An error occurred while sending a message to H0109401.

The message alias could not be found on the network.

More help is available by typing NET HELPMSG 2273.

-------------------------------------------------

Seems that the problem is the same ...
