Resolves and places the results into cache for the DNS names on the computer.
You can leave this service on manual if you are not connected to a DNS server. If you are connected to the internet then leave this on automatic. In our experience it is better to leave this on automatic.

This manages the objects in the Network Connections folder from where you can see the local and remote connections.
If you have a PC that is connected to the internet then leave this on automatic. If you don’t use the internet or another network then you can leave this on manual.

Conserves the date and time synchronisation between the client and servers on networks.
By default Windows XP tries to synchronise its clock with an internet server so that the time is always correct. Leave this service on automatic if you want to be able to use this function.
