Single Machine but with Multiple IP addresses

[A1E5D4]

Please help. Am I hacked or not? My problem is: I found multiple (three) IP addresses assigned to a machine by DHCP. The machine has only one network card and I don't have VPN connection for the machine. Here is the information from the wireless router:

Host Name IP Address MAC Address Expired Time
DDDxxxxx 192.168.0.111 00-90-5B-26-AD-60 Feb/03/2004 18:34:46
DDDxxxxx 192.168.0.113 5241532000905B26AD60000001000000 Feb/03/2004 18:33:02
DDDxxxxx 192.168.0.112 5241532000905B26AD60000000000000 Feb/03/2004 18:32:08
LLLzzzzz 192.168.0.121 00-07-8D-45-3A-37 Feb/03/2004 21:11:07

I have home network with cable modem and wireless router (D-Link). I have two computers connected to the router with Ethernet cable and one laptop using wireless card. The problem machine has Kerio Personal Firewall and Norton AntiVirus.

If I am hacked, what should I do to solve it? If not hacked, why is it so? Thanks in advance.

What happens if you do a release/renew?
Start -> Run-> CMD (command in Windows 9x)
In 2K/XP:
ipconfig /release
ipconfig /renew

In 9X/ME:
ipconfig /release_all
ipconfig /renew_all

After completing this, redo a ipconfig and see what it says now.

Thanks, Xemus. I don't know what happended but the problem dissappeared when I check the status report. I know the problem will mysteriously come back, as it had happened a few times. I will try your recommendation and let you know the result.

Xemus, the problem happened again but to my laptop which is running Windows XP Pro, Internet Connection Firewall, Norton Antivirus, and Ad-Aware. I run Norton Antivirus and Ad-aware everyday and found no problem. I did the release and renew but still have the problem - three ip addresses assigned to the same machine. I called the tech service of my wireless router and they said my machine must be hacked by someone very skillful but did not know how to solve the problem. Please help!

What happens if you turn off DHCP and just assign manually?
I can't see the point of having DHCP if you only have three machines. Still it may be a preference thing which is cool but see how it goes.

Elmurado, thanks. I don't know how to turn off DHCP. I am using D-Link wireless router which has DHCP as built in. Could you give me some guidelines? Thanks.

A1E5D4 - You can leave DHCP enabled on the router, just go to the TCP/IP properties for each PC and select "Use the Following Address". Then type in an IP address that is on the same subnet as your router (in your case - 192.168.0.???). Address one of your PC's 192.168.0.11, the 2nd PC 192.168.0.12 and the notebook as 192.168.0.13. You will probably also need to add a Gateway (which will be the address of your router - most likely 192.168.0.1). Restart the PC and you should be set. The router will still be configured to dynamically assign IP addresses, but the individual PC's won't be asking
