Dhcp - PLEASE HELP!!

[2jamesl]

ok im back, it's me again and i now know that the reason that my media connect wont funtion properly is because of the Dhcp. It encounters an error every time i turn the PC on, please help me!!

[SneakyNeil]

Whats the error?

Dynamic Host Control Protocol.

Your router will have a DHCP server on it, although it might be upset about ICS appearing which also has a DHCP server built in to it.

As above, what's the error?

'The IP address lease 172.367.2.7 for the Network Card with network address 0016668567E2 has been denied by the DHCP server 172.367.2.8 (The DHCP Server sent a DHCPNACK message).'

That's a public IP address

Start >Run >cmd

From the command prompt

Ipconfig /release


Then reboot.

It's also malformed ... 172.367.2.7 ??? I'm hoping that's 172.36.72.7

Do you have a feeling there's potentially multiple useable IP's supplied by the ISP and a badly configured DCHP server on the router?

i made the I.P up because im not going to post it.
well at least, i dont think i should??

Didn't notice the typo

Could be a 172.16...

Ipconfig /release would still be my first step as it's requesting a DHCP addy the server won't dish out.

If it's an internal (private) address, there's no problem with posting it chap..

[2jamesl]

The IP address lease 192.168.2.2 for the Network Card with network address 00111166C3E2 has been denied by the DHCP server 192.168.2.1 (The DHCP Server sent a DHCPNACK message).

is this ok to post or shall i delete?

That's fine... Sounds like your DHCP server has access control set up and your MAC address isn't in the allow list. Well, that's one of many potential reasons for the problem.

Why not just assign your IP statically if you can't find the reason why it's happening.

i wouldnt know how to do it. Do you have any simple suggestions?

[2jamesl]

How about i type services.msc into run and then go to windows media connect, it is currently set onto this network 'NT AUTHORITYNetworkService'. How about i set it so that it runs on 'local system account'

[BliarOut]

Noooooooooo

It's an IP thang...

On the good machine

Start >Run >cmd

Ipconfig /all


Note all the numbers etc


Then right click your LAN connection > Properties >Internet Protocol TCP/IP and enter the same info there EXCEPT make the IP address one digit higher.


Then you should be able to ping etc. to test it.

where do i find my LAN connection?

[BliarOut]

Start > Network connections or in the control panel under the same name.

[theboss]

How many PCs or other devices (i.e. xbox, wireless access point, network printer, etc.) have you got on the network?

Also can you get onto the administrative webpage for your router?

It sounds as though your PC is being refused a DHCP lease which would indicate that you may have some duplicate IP addresses on the network and/or possibly an insufficiently large pool of DHCP addresses on the router.

Rather than give your PC a static IP address it would be better to sort the problem and continue using DHCP, this could be as simple as clearing the DHCP lease database (power off the router) and/or extending the pool of client addresses.

True, but the op needs assistance to find where the LAN settings lurk!

yes i did that but it was local area connection - LAC rather than LAN and i couldnt see where to do the protocol. Im gonna need a tutorial guys!


thanks

Yes, LAC = LAN.

Right click. Properties. If Windows is behaving then your looking at a Windows full of oddities.... that I can't remember as I'm using a Mac ATM
But once that's up go back up the thread and follow the others advice.
