Network Wizard

[Lloyd]

I am running two desktop PC's, one with WndowsXP Pro and
the other using Windows XP Home Edition.

Whilst setting up a home/small office network using the
network wizard i have mistakenly( by running the Network
set up wizard twice on each PC) set up four computers in
the network instead of two.

Please can you tell me how I can remove the erroneous
entries(spelt in different case) from my network
workgroup.

Thanks
