Det er temmelig sikkert tjenesten Messenger (ikke at forveksle med 
MSN Messenger).

| Messenger ~ sends messages between clients and servers. This
| service needs not to be running under normal "home" conditions. 
| It is also advisable to make this service go away to avoid the 
| possibility of "net send" messages hitting your computer from the 
| internet. This has nothing to do with MSN Messenger, nor is it 
| "WinPopUp". 
|
| To test for this security vulnerability, at the command prompt,
| (run: cmd.exe) type: 
|
| net send 127.0.0.1 hi
|
| If you get a popup "hi" message, you should disable the Messenger
| service. 
| If you get an error stating, "The message alias could not be found 
| on the network", you are safe.
|
| If, for whatever reason, you need the Messenger service running
| but wish not to have spam popups active, you can disable the
| particular ports at your firewall. The Messenger service uses UDP
| ports 135, 137, and 138; TCP ports 135, 139, and 445.

| Dependencies:
|
| NetBIOS Interface 
| Plug and Play 
| Remote Procedure Call (RPC) 
| Workstation
