think he means swtich them on and off in order. sometimes i have to do this on my network - kinda like restarting/rebooting the network.

If you have any firewalls on any of them, including Windows firewalls you have turn them off or learn how to set them up to incorporate your network users into the network. Windows XP firewall likes to turn its self on automatically.

Also if you're using a router for the Internet gateway you'll have to include all of the local IP addresses to be allowed full access.

Have you and your sister set up shared folders?

could your brother have automatic updates on.. if so XP may have installed something to protect his computer..that would explain why its only his too..

i'm not familiar where to find the setting for the firewall of the windows XP.. we don't have a router installed just the 16 port switching hub... and yes i think my brothers auto update is enable... if so(auto updates enable) what can we do to to undo the changes or is there any thing we can do for his pc to be seen on the network again (file trasnsfer enable)and at the same time connect to the internet...

thanks for the help guys... please bare with us until we've solved our little crissis...

thanks again

Go to > Start Menu>Control Panel>Windows Firewal> And Select turn off

Simple method to disable and enable Windows Firewall:
http://www.microsoft.com/windowsxp/using/networking/learnmore/icf.mspx

unfortunately sometimes XP firewall will re-enable itself if switched off this way; the better method is to disable the service:

control panel>Administrative Tools>Services>right-click "Windows Firewall/Internet Connection Sharing (ICS)" and goto properties>select disable

that will completely disable the firewall service. please be aware that a third party firewall should be installed if u do this - ZoneAlarm Firewall is a free to use firewall.

when setting up the network did you run it on the XP machine first using the network Wizard and create the network floppy disk to use on the other machines?

personally i really wouldn't stop the XP machine from receiving it updates due to all the security holes...

Disabling automatic updates is not an issue, that if you check for new or highly critical updates manually from time to time..

firewall can be a bad thing sometimes. if u want to disable firewall, i suggest u use mozilla firefox<------foxes are cool

bdly configured firewalls are bad and so is the one with Windows XP - since there are better free alternatives out there i always recommend ppl use them instead of the XP one. But under no circumstances would i ever consider disabling my firewall for anthing longer than a few minutes; to comprise internet security any longer than need be is reckless.
even if u use firefox u will still need a firewall; the only benefits for firefox is the spyware/virus issue.
