dhcp server unavailable: renewing adapter "PC1002"

[gt6350a]

I can not connect to the internet on my Dell Laptop runing NT 4.0 sp5. I have the settings on the laptop the exact same (DHCP, etc..) as my other NT computer that will connect to the internet. I keep getting this message when I run a ipconfig /rewnew:

dhcp server unavailable: renewing adapter "PC1002"

Any ideas folks?

Why don't you just input the Local IP, DNS and gateway address manually.

i did that, and made it static, but it does not work.

You don't mention the network setup, so I am assuming that you do not have a network. Where are you trying to get the DHCP address from?

If you do not have a DHCP server, and are trying to get it from your ISP, then you need to let the ISP know and then they will provide you an additional address--for a price.

yes, i do have a network etup. all my computers are running dhcp. i configured this current computer exactly like my pther NT4.0 computer in the network settings. still, no dice.

Do you have a private or public network?

What type of device is running DHCP?

Have you exceeded your scope of addresses?

he bob:

below please findthe answers to your questions..

Do you have a private or public network? Private

What type of device is running DHCP? Client (XP os)

Have you exceeded your scope of addresses? No, if I turn off one computer and hook this laptop up, there should be at least one extra address. Even that does not work.

 

[Whoheard]

What address scheme are you using? Can you provide the network address and the subnet mask being used? Can the client ping himself and the loop back address?


bob

 

[gt6350a]

address scheme 192.168.2._____

network address: ? it's DHCP

Subnet mask: I dont know where to specify this, I thought it would just detect the correct mask...

the client can ping: loopback only

 

[gt6350a]

UPDATE:

when i put a static IP address in, the client can ping itself....

 

[Whoheard]

Being able to ping the loop back and a static IP means the card drivers are loaded and seem to be functioning.

Under the TCP/IP settings, what mask did you use? You can view this by issuing the ipconfig /all statement at a command prompt; or by looking at the NIC properties.

The mask determines the number of IP addresses that can be used on the network, the Network ID and Broadcast address.

If you have a 192.168.2.X network, the default subnet mask should be 255.255.255.0. This will give you 254 address spaces. What scope of addresses did you define under DHCP, and what type of device is serving up the DHCP addresses?

where can i specify the mask? if you choose DHCP, the mask can not be specified i thought. i am looking now and i do not see a place to specify the mask.

my router is giving the clients the private addresses

 

[Whoheard]

You do not configure it if you are using DHCP. You let the DHCP server give out the info. Your router must have this configured, and problably does. Your problem might be the lack of addresses available under the scope of the DHCP settings. Is this a home network? What type of router are you using?

issue a ipconfig /all in DOS window and it will tell you the mask and all information about the TCP/IP settings--DHCP or Static.

Ping your default gateway and see if you can see it.

bob

 

[gt6350a]

i did all of that...it returned

ip address: 0.0.0.0
subnet mask: 0.0.0.0
default gateway: (blank)
dhcp server: (blank)

there are plenty of IP addresses left over. my router has about 200 left over to assign me.

 

[Whoheard]

What type of router is this?

If it is a Linksys for home use, there is a setting that limits the number of addresses regardless of the scope range.


bob

 

[Whoheard]

What info did you use when you assigned it a static address?

 

[gt6350a]

it is a linksys dsl/cable router however, when i turn off one computer that has leased an IP from the router i still do not have an 'extra' private ip forthe laptop, even after i just free-ed up and extra ip by turning off my computer. i am stumped!

 

[Whoheard]

The DHCP table maintains a cache table of MAC addresses and may prevent you from getting another address regardless of ip usage. Check you settings under dhcp in the router and set the number of available addresses to more than 50. 50, I think, is a default setting.

bob

 

[gt6350a]

i thought routers delt with ip addresses and bridges and switches delt with MAC addresses. do you agree?

there are a total of 15 computers in this office setting. at most 30 MAC addresses would have been cached, but realistically, 20 have been cached if the router is caching MAC addresses. strange?...

 

[Whoheard]

Yes, true, but your are dealing a Linksys router. There firware is a bit fickle. I have not had much luck with all devices using dhcp on a Linksys. How many users are authorized in the dhcp pool?
