invalid IP


Recommended Posts

i got five computers on a network.. one as the server which is online through an ISDN connection and the others connected to it via a hub..

i'm havin difficulty connecting one pc to the network.. it keeps on saying invalid ip.. in the network status. although the IP is set to obtain IP auto matically..

does anyone know a solution..

all the pc's are runnin winXP

thanx

but it still doesn't work.. i still get invalid IP

this system was used as the server before.. cud this have something to do with it.?

instead of having it automatically get an IP, just give it one manually. make sure its in the same range as the other computers on the network (IE if the others are 192.168.0.2 and 192.168.0.3 etc make sure you have this one as 192.168.0.x) and in the TCP/IP settings, just point it at your server's IP for DNS and gateway stuff. that should do it.

Yup.. did that tooo..

i have been into networking for quite sometime now.. i mean not a n00b.. but i for the life of me cannot figure out why it's givin me that problem....

oki.. am gonna try that.. thanx

Why don't you just clear the DHCP Routing Table. :D

Then restart Each machine. That way the DHCP can reassign all computers a new IP. (Y)

thanx.. rezza... that did the trick :)

Not really the best way to do it though. Give xStainDx's solution a try. Not really a good idea to set a static ip in the same range as your dhcp ips, especially if you add/remove pcs all the time.

bah. as long as you remember what IPs your computers are using, there'll be no problems whatsoever. Personally I always configure my network like this, manually setting each machine's IP address, and disabling DHCP altogether. Using DHCP can increase boot times as boxen wait to get assigned their IP from the server... but if they already know their own IP, there's no waiting!

(BTW my way only works for small networks... if you run an office or something then DHCP is really the best way to do it... individual manual IPs will become a nightmare quickly with more than just a handful of machines)

What he is suggesting is to give a static ip to a pc while still having DHCP enabled for the rest. I have nothing against static ips if you have a small network. You shouldn't mix the two in the same address pool though.

Well, the way I setup networks with DHCP is to include a range (# in the range depends on the total # of computers) of IP address that are in the same subnet but EXCLUDED from the DHCP range. This way, you have static IPs to work with and you won't have to worry about DHCP passing out one of your "static" addresses.

For exapmle:

DHCP range: 192.168.100.25 - 192.168.100.254. *Notice the first 24 addresses are not available for DHCP to hand out. This allows me to use them for static purposes.

That's what I'm suggesting to do:))

aadhu said he tried it out and didn't work for him...not sure why it wouldn't. aadhu, I know you said you have enough experience in networking but are you sure you you were using a valid/unused IP?? I've made that mistake a few times:))

Umm... what? I never said that anything didn't work :blink: using static IPs has never failed me yet...
