Install the latest IM (Instant Messenger 4.6 for all Windows versions prior to XP) -- can download with Microsoft. This version lets you set it up (in the Options menu) for either or both Exchange Messaging (inside company) and .NET Messaging (outside company). To restrict users from getting to the Options menu and changing that back themselves you can do one of two things: - Set IP filters in your firewall so it blocks the IM ports (users can still change the option, but will get errors when trying to connect to outside) - Make the following entry in this registry key (disables .NET Messenger service): HKEY_CURRENT_USER\Software\Policies\Microsoft\Messenger\Client\{9b017612 -c9f1-11d2-8d9f-0000f875c541} REG_DWORD set to 1 Hope this helps. -----Original Message----- From: Eric Lanyon [mailto:elanyon@xxxxxxx] Sent: Wednesday, May 08, 2002 10:37 AM To: [ExchangeList] Subject: [exchangelist] Messaging Question http://www.MSExchange.org/ On Exchange, it can integrate with Messenger, right? Can you set it up so the clients can not "chat" with those external to the company? How? ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: alopezdeayala@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
