what is svchost

i have currently upgraded from win98se to win xp pro there three svchost

in the task manager and zone alarm is alerting that svchost is trying to

connect to the internet what should i do ?

 

In Windows XP you have services running from dynamic-link libraries (DLLs). At startup, Svchost.exe checks the services portion of the registry to construct a list of services that it needs to load. And as you saw, there can indeed be multiple instances of Svchost.exe running at the same time.

Here's some reading: A Description of Svchost.exe in Windows XP (Q314056)

It's perfectly OK to let it connect.

 

By default, WinXP uses svchost to connect out:

1) IGMP protocol to MCAST.NET - which allows internet hosts to participate in multicasting.

2) UDP protocol via port 1900 - Universal Plug N' Play (UPnP)

3) UDP protocol - time.windows.com for clock regulation


ZoneAlarm is just alerting you to these outbound connections.
