Windows Server - net send error 2237

Hi,

In the domain network of our work some users cant receive a net send
message. Sender receive the error 2273.
We use the net send with username instead of computername or IP
because we need to do it.

We solve some cases changing the logon name of these users on active
directory, but I dont think this is a good solution.

The computers are Windows XP Pro SP3 with Messenger service running.

Suggestions are welcome :)

Thanks, regards.

Hi,

The correct error number es 2273.

The problem is here: http://technet.microsoft.com/en-us/library/bb490707.as=

It says when you login your username is added to "net name" alias list for =
messaging, but I have many users that login to domain controller but her us=
ername isn=B4t added to "net name" alias list. Then, they cant receive mess=
ages and sender gets the error.

Thanks, regards.
