Winsent Messenger can receive messages from and send messages to computers that have either Winsent or a compatible program installed. The term "compatible" means that the program uses the same message transmission protocol as used by Winsent. Among these are, for example, two standard Windows programs used for popup messages exchange. Microsoft Windows, depending on the version, is supplied with one of two standard programs with the help of which you can receive messages from and send messages to computers with Winsent:
- "Messenger Service" on Windows NT, Windows 2000, Windows XP, Windows 2003 Server operating systems ("net send" command). Read more about net send command and Windows messenger service;
- Microsoft Winpopup on Windows 95, Windows 98, Windows ME operating systems.
Also, there are third-party software products that are compatible with Winsent, Messenger Service and Microsoft Winpopup.
In case the Winsent is not installed on all computers, make sure, that computers you want to communicate with have one of the aforementioned programs installed and running.
Windows Messenger Service was removed in Windows Vista/7/8. If you use one of these operating systems, you have to install Winsent Messenger/Winsent Innocenti or a compatible third-party software product to be able to receive messages from and send messages to computers with Winsent.
In order for Winsent Messenger to work properly some of the Windows system settings must be configured on all computers running the program. Read the article for more details.
Winsent uses the same ports that are used by Microsoft WinPopup and Windows Messenger Service (net send), namely UDP ports 137, 138 and TCP port 139, 445.
Yes, the Messenger Service must be disabled (for Windows NT/2000/XP). Read the article for more details.
In order for Winsent Messenger to work properly some of the Windows system settings must be configured before you run the program. Read the the question How do I setup my computer for Winsent Messenger to work properly? for more details.
Complete the following steps to install Winsent Messenger:
- Download Winsent Messenger installation package (winsent-setup.zip).
- Extract content of the archive into directory you like, for example "My Documents".
- Run setup.exe.
- Follow setup program instructions.
The .exe installer for Winsent Messenger supports two command line parameters for a silent install: /silent, /verysilent.
The common way is to use .msi installer and installation through Group Policy.
Winsent relies on the Netbios protocol so you need a Netbios name resolution mechanism, that works across subnets (WINS for example). This will allow Winsent to send personal messages between computers in different subnets. Broadcast messages are only delivered to computers on the same subnet with message sender (unless routers are configured to forward Netbios broadcast traffic between subnets).
To send a message to several recipients at once, enter the recipient names in the "To" field of the new message window, delimiting them with commas.
WinSent configuration information is stored in Windows registry. Most settings are stored under key
"HKEY_CURRENT_USER\Software\Winsent Software\WinSent Messenger".
Value of option "Launch Winsent on startup" stored under key
3.3 Where are WinSent message archive and contact-list stored?
Message archive file and contact list file are placed in %APPDATA%\WinSent Messenger\<version> directory.
3.4 How to send a message from command line using Winsent?
Winsent does not support command line parameters for message sending. In order to send "net send" message from command line use the Sent utility (see Net send messages from command line of Windows 8/7/Vista).
This message usually means that there is another messaging software running on the same or another computer that uses the same network resources (messaging names). This might be the standard Windows messenger service, Winsent Innocenti or a third party "net send" compatible software. You have to uninstall or disable this kind of software on your computer. Also, make sure that each user on your LAN is logged on under their own unique name and user names differ from computer names.
This usually means that there are no active network interfaces with "Netbios over TCP/IP" option enabled on your computer. Enable the option.
There is a number of possible reasons:
- Network and system settings do not meet the requirements. Make sure that all the requirements are met (see the article "Windows settings requirements").
- There is another messaging software running on the same or another computer that uses the same network resources (messaging names) (see the question N 4.1).
- The computer you are sending the message to does not have any compatible messaging sofware installed and running. Make sure that the sofware is installed and running (see the question N 1.2).
- A recipient with specified name really does not exist. You can use the following names as recipient names: computers network name, user login, workgroup or domain name.
- The recipient is located in another VLAN/subnet. Setup Netbios name resolution in you network (see question "Does Winsent Messenger work between different VLANs/subnets?").
Enable "File and printer sharing" exclusion and the following ports: UDP 137, 138 and TCP 139, 445 in Windows Firewall (Windows XP/2003/Vista/7/8).
Enable "Network discovery" and "File and printer sharing" in your network profile (Windows Vista/7/8).
