‘net send’ vs msg.exe
This article aims to investigate the possibilities, limitations and differences between the old NT command “net send” and the newer msg.exe utility.
net send (usage: net send [computername] [message]
Conditions:
- The machine must be running XP or 2003 Server (net send is not available in Vista, Win7 or Server 2008
- The service “Messenger” must be running (sending and receiving machine) It is disabled by default from XP sp2 and later
- NetBIOS must be enabled (sending and receiving machine)
- The ports 137/UDP and 139/TCP must be open (receiving machine)
- Domain-independent
msg.exe
Conditions
- Available in 2003 Server, XP sp2/sp3, 2008R2, Vista, Win7
- Sending and receiving machine must be members of the same domain
- Not NetBIOS dependent
- Only uses port 445/TCP (SMB)
- Possible to use IP instead of machinename
- Not dependent on the messenger service.
Note: If you have trouble with “Access denied” problems, try this registry hack: Locate the DWORD key “AllowRemotePRC” in HKLM/System/CurrentControlSet/Control/Terminal Server. it should be set to “1”.
If none of these meet your requirements, the following third party softwares are available:
- Net Send (freeware=
- WinMessenger (freeware)
- LantalkNet (shareware)
