JSI Tip 6273. How do I prevent users from sending popup messages?

Windows NT-based operating systems (Windows NT, Windows 2000, Windows XP, etc..) use the Messenger service for sending popup (net send) messages. If you stop the Messenger service, popup messages cannot be sent.

To configure Windows NT-based client computers to not start the Messenger service:

1. Use tip 4195 to run:

Workstation DomainName DomainAdminAccount DomainAdminPassword WS %LOGONSERVER\NETLOGON\NoMess.bat %LOGONSERVER\NETLOGON\NoMess.log
where NoMess.bat contains:

@echo off
net stop messenger>nul 2>&1
@echo REGEDIT4>%temp%\nomess.reg
@echo \[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Messenger\]>>%temp%\nomess.reg
@echo "Start"=dword:00000004">>%temp%\nomess.reg
regedit /s %temp%\nomess.reg
