XP, network configuration?

If your office network is through a server then this is a domain network. At home the network is most likely a Workgroup network.

To use a computer on a Domain network, you must have XP Pro, Vista Buisness, Vista Ultimate. The Home editions will not work on a Domain. They keep disconnecting.

In XP pro you just create new network connections, rename them and you right click them and enabel to use them or right click disable to not use them

click Start >Network connections (located just above printers and faxes) on the RHS you can create a new connection. You can have as many as you want. Just enable one though. If you stay at a hotel, you can have one to suit the hotel for example.

I suggest to update to XP Pro, only cost a few bucks.

You can use the alternate settings in XP for a second network. If you use the "Obtain and IP address automatically" option for the first network the tab for "Alternate" settings appears. Add a static IP in there.

Unfortunately not unless you have two network cards installed on the laptop that you can set different settings for

properly.... i'm uncertain if this solutions your question or not besides the undeniable fact that i in basic terms offered a fix DISC from my producer so i ought to repair my finished computing device and it works great now... I had viruses that my virus protector did not capture....
