I just setup a work-group network with 4 client computers and a network printer. All computer have dynamic ip expect the printer that have static IP and they all runs on windows operating systems and as follow. 2 computers runs on windows vista home premium, 1 windows 7 and one windows XP. Each time i connect the computer running windows XP to the network, every other computer on the network get disconnected and the computer won't receive ip from the DHCP server as well. I would like to know the cause of this problem and a possible solution.

Hi,

you may have a bad Nic and its flodding the network with bad packets.
Try using a differernt Nic in the XP system.
(could also be some sort of malware (virus) on that XP system.
Is the wiring and Jack known good that the xp system is connected to?
otherwise try another wire/jack.

If i connect the XP system directly to the business router from the ISP it works perfectly but if i connect it to the workgroup network won't connect and it would be displaying an icon in the notification area saying plugged and unplugged with an interval of like 3 seconds. I got 2 Nic on the system and have tired the two and keep having same problem.

Try these
1) going into the Nic settings and set the nic card to 100/full instead of auto/auto for speed/duplex settings. (they may be in colflict to what the switch has set in your workgroup)
2) are you using DHCP or static IP addressing, - check for duplicate ips's

Try resetting the TCP/IP stack on the XP PC that is causing you trouble by typing the following at the command line:

netsh int ip reset reset.txt

As stated previously you are most likely flooding the switch/router whatever you are using.
If this is a switch not sure which because you did not specify (smart switch, dummy switch) the duplex speed is most likely causing an issue. As some stated previously you have to change the duplex on the nic as well as in the switch if it is a smart switch. When speeds do not match you get this issue. The nic could also be set to a speed higher than you switch/router can handle and this will shut it down and it will show as disconnected. To me this seem like a network speed issue.
