Conflictin IPS address on my system

**barbaro** · 04-03-2009, 01:27 PM

I am getting the alert a couple of times that says to paraphrase:

"This IPS number is in conflict with another system on the network."

What does this mean?

TIA.

**Marmite the Dog** · 04-03-2009, 01:30 PM

What is telling you about the conflict?

**Thetyim** · 04-03-2009, 01:32 PM

Change your IP address.

Click Start, Run. Type cmd. Press Enter.
Type "IPCONFIG" and make note of your IP address.
Type "IPCONFIG /release" without quotes and press Enter.
Type "IPCONFIG /renew" without quotes and press Enter.
Type "IPCONFIG" and see that the IP address should have changed.

^ unless you have 2 DHCP servers running on the same network handing out the same range of addresses.

or it could be someone else has manually assigned themselves and address that is in the DHCP servers assigning range.

if Thetyims advice does not fix your problem ( do " ipconfig /all " ) you will need to first describe to us your network layout.

**barbaro** · 04-03-2009, 08:20 PM

thetyim,

Thanks, for info. Just do what you said? I won't screw anything up?

Marmers, that's all it says. I run Windows XP: a yellow triangle with an exclamation point appears in the lower right hand side of my browser.

If someone in my account? Tapping into my line.

And thetyim, everytime I turn off and then on my computre and get online, I get a new IP address, right?

Thanks again.

**hawkeye** · 04-03-2009, 08:27 PM

Have the same problem, in fact it has been popping up on the screen for a couple of months.
Just followed Thetyim's advice and no change to the I.P. Address,or the Subnet Mask numbers, or the Default Gateway numbers.
What to do? Any advice?.......... thanks

Yes but that is upstream of your router, I expect your problem is downstream of the router and you have an IP address assign twice

**friscofrankie** · 04-03-2009, 08:55 PM

pretty hard to do with DHCP on your network, if you use it. to have a conflicting IP you need more than one machine on your internal network, your router could be that second machine. SO; if you have only one PC on your internal net and are getting a conflicting ip address a person could be excused for thinking you have hard-coded an IP into the network properties and it is one that conflicts with your router (or another machine if you have two or more machiens internaly).

DO what baldrick said ( ipconfig /all ) and post the output here. Then one of the MS weenies will be able to get you fixed up.

Have just taken BALDRICK'S advice (ipconfig/all) and following is the output,

Windows I.P. Configuration

DNS Servers 192.168.1 .254
Lease obtained Wed March 04 2009 8.21.50 pm
Lease expired Thurs March 05 2009 8.21.50 pm

Not knowing really anything about how all this works perhaps some one can help me to fix this.
Does this problem mean that some emails sent to me may have gone elsewhere?
Thanks

PS Thanks Milkman for starting this off.

It is someone on your LAN (after your router) who is using the same IP address
as the one you have assigned.
Are you using a wireless router without having it secured?

no - except for some really extreme circumstances.

need to clarify what the network setup is that you have.

is the main modem/router yours ? are you sharing your connection via the router ethernet/wifi knowingly with other computers.

it might also be helpful if you tell us the manuf and model of the router/modem now in case we have to help you secure the unit.

My router is wired.

Secured? What do you mean?

I don't understand. Sorry.

I understand a little - I think.

OK.

But is it REALLY necesarry?

Does it matter?

Secured? What do you mean?

A wireless access point router can be "open" so that anyone can connect to it, or secured with password.
But since you don't have a wireless router it must be something else.
You have more than one computer connected to the router?

**baldrick** · 05-03-2009, 08:56 PM

do you have wifi on your modem/router ?

the IPconfig /all command would have allowed us to see the config of all the network interfaces on your pc - there is a chance ( small ) there could be a conflict there.

your router/modem has 2 main sections - the side that is connected to your internet service provider ( ISP ) which is called the WAN ( wide area network ) and it probably recieves an new IP every 24 hours from the ISP or every time you power the unit off and on.

the other part is the LAN ( local area network ) - this can be wired or wifi and it is your personal network. the IP addresses on your LAN can be assigned by a DHCP server running on your router LAN section or manually assigned by you on a computer or device. If on your LAN your DHCP server is configured to assign addresses between 192.168.1.100 and 192.168.1.149 and something else on the network has been manually configured to have an IP of 192.168.1.100 you will end up with 2 devices on the LAN with the same IP which caused confusion as to who should recieve packets to that addresss.

there a other scenarios for 2 of the same IPs to be on the same LAN segment , but I don't think they are happening here.

knowing what and how you have your network setup makes it much easier to diagnose the problem.

**barbaro** · 07-03-2009, 02:39 PM

Thanks for the responses.

To answer a question above, no I only have my laptop on this router.

**baldrick** · 07-03-2009, 02:55 PM

is it a router/modem combo ?

is it your router ?

does it have wifi ? you are connected via LAN to the router ?

I don't understand. Sorry.

He's talking about the external network, WAN (which is 'upstream' from your router to your Internet Service Provider) and the internal/local network, LAN (which is 'downstream' from your router [all machines that are connected within the local network and have to pass through your router in order to access the WAN and the Internet]).

Your router is assigned an external IP address by your internet service provider. This IP address is the one you see Blackgang's signature reporting, and the IP address you can see next to a poster since you are a moderator.

But this is not the IP address you are having trouble with now.

What your computer is telling you is that there is more than one device inside of your local area network that has been given the same IP address.

People are asking about Wireless because if somebody close enough to your router finds you have an unprotected wireless network, they can use it, and when they do, the DHCP server (the program inside your router that handles the automatic assigning of IP addresses within your network) will give the computer of the sneak an IP address. And if that is the same as the one you are using on YOUR computer, then there will be a conflict.

**barbaro** · 08-03-2009, 12:34 PM

Baldrick: I don'w know.

Frankenstein: Should I be concerned?

As long as someone is not snooping around my computer.

**baldrick** · 09-03-2009, 01:59 PM

what is the manuf and model of the device connected to the phone line ?

does your computer connect to that device or another one ?

**barbaro** · 09-03-2009, 03:22 PM

My router?

It's a SEIMENS Gigaset SE260 dsl

does your computer connect to that device or another one ?

All I know is that it's DSL (I think). Or ADSL.

**baldrick** · 10-03-2009, 09:38 AM

ok - ADSL modem with 1 LAN port ( and 1 USB ? )

can you do a ipconfig /all to look at all the IPs of the network devices on your computer.

as you say that you are the only computer user and you are connected by wire to the modem ( LAN or USB ? ) and there is no wifi we can rule out some one else using your connection.

if you are using a laptop there is a chance that the IP assigned to you by the modems DHCP server is the same as a manually assigned IP to the wifi Network Interface Card ( NIC ). when you do the ipconfig /all in a DOS window you will be able to see all the NIC's and their corresponding IP addresses and other pertinent info.
