NetMessageBufferSend differences on win2k and NT

I have managed to create an app that uses the NetMessageBufferSend but I created one in vb a while ago and it would only send the message if the reciepant name was the either a valid username or the same as from name (this was on winNT4)

Where as this new app i wrote i can set the from name as anything i like although i have only tested it on win2k, does anyone know of any differences?


Thanks

Windows NT: No special group membership is required to execute the NetMessageBufferSend function on a LAN Manager or a Windows NT system. Admin, Accounts, Print, or Server operator group membership is required to successfully execute NetMessageBufferSend on a remote server.

Windows 2000/XP: If you call this function on a domain controller that is running Active Directory, access is allowed or denied based on the access-control list (ACL) for the securable object. The default ACL permits only Administrators and account operators to call this function. On a member server or workstation, only Administrators and account operators can call this function. For more information, see Security Requirements for the Network Management Functions.
