I notice that the Messenger service stops when I start the LanToucher application. Why?

LanToucher Messenger does not use the Messenger service to send/receive messages since it has its own implementation of the Server Message Block (SMB) protocol. That's the reason why the service stops.

Can LanToucher Messenger send and receive IMs from AOL IM?

LanToucher Messenger is designed for private corporate and home networks. Therefore it cannot receive and send to public Internet messengers such as AIM, MSN or Yahoo! messengers.

Is it possible for LanToucher Messenger to act as an Email-to-IM gateway?

No, this is not supported as LanToucher Messenger is a "closed" messaging system. It's designed strictly for internal local area networks.

Will it automatically "find" the other clients?

Yes, but first you should add them to your contact list (ActiveList) from Contact Browser. Hit F3 to open the Contact Browser dialog.

If my computer is switched off, will LanToucher Messenger store all my previous messages?

Yes, it stores all your messages in the message log permanently. Until you delete them.

Is there any way to retrieve deleted messengers from LanToucher Messenger?

There is no way to recover deleted messages.

I want to have all of the messages archived on a server for HIPPA and other regulatory issues. Is this possible with LanToucher Messenger?

LanToucher Messenger stores all messaging in its internal database. Each LanToucher Messenger user (except for TS and RDP users) has their own message database. The message bases can be exported to a text file for archiving.

We are in a TS environment. Does that help in regards to archiving messages?

In a TS environment the application is run off the server. Thus, your users' message storage files are created and stored in a single location on the terminal server, in the LanToucher Messenger folder (by default, C:\Program Files\Vital Sound Laboratory\LanToucher Messenger).

Is LanToucher Messenger secure and safe to use?

With LanToucher Messenger, the messages are sent over your secure intranet directly from the sender to the recipient (host-to-host) using the SMB/CIFS protocol. Simply put, it is not possible to send messages to the outside world (the Internet). Please be advised, that the SMB/CIFS protocol does not allow message encryption.

Is there any way to send offline messages?

Offline messaging is not supported at this time. A user can send messages only to those persons who are online.

How do I broadcast to certain groups without sending to everyone logged onto the network?

With LanToucher Messenger, you can use preset groups for this. Sending to a group is as easy as sending to a single contact. To create and populate a new group in LanToucher Messenger, select ActiveList from the main menu, then click Manage Groups or just hit CTRL+G.

Can I set up "quick messages" in LanToucher Messenger?

Yes. With LanToucher Messenger you can quickly insert a pre-defined message or word (message template) into your outgoing messages by hitting a function key or selecting it from a pop-up menu. For more information on macros, see the LanToucher Messenger help file (Go to User Interface > Options dialog > Macros).

How to change my user name?

  • Open the Options window (Ctrl+O).
  • Click the Misc tab.
  • Specify a new messaging name in the 'Override default user name' box.
  • Restart LanToucher Messenger.

Make sure that your computer name does not match your user name. Also check if your user name is unique within the network.

Can I be signed in to LanToucher with the same user name at the same time in 2 locations?

If you sign in with the same user name at the same time, only one instance of the program will be able to send messages from that name, all other instances, will use computer name as the primary messaging alias.

Is it possible for an unattended application (e.g. a database server or a backup software) to use LanToucher to send IMs to other clients via command-line?

Sure, please see the Command line interface topic in LanToucher Messenger help for more information.

Can user settings be locked by administrators?

You can use LanToucher Messenger Policy keys to configure this.

Can the pop-up feature override the DOS box and come to the foreground?
