[resolved] Can't connect to LAN

jee · 07-30-2005, 09:41 AM

I had a power outage a couple of weeks ago and now I can't connect to my LAN or the internet.

I have a router for a DHCP server, when I boot up I get a IP address and my lease is renewed. When I open open a browser nothing will open, not even the setup pages on the router. When I run winipcfg I can see my IP address, DNS address, ect.... but if I try to renew I get a error message that says "DHCP server unavailabe: Renewing adapter"

In the Device manager every thing is working however I have unintalled and reinstalled the ethernet adapter several times. The original adapter is onboard. I have disabled it and installed a PCI adapter. Same results!

It seems as though once Windows is fully up some software is blocking the adapter. I have uninstalled the firewall I downloaded 3 or 4 mounths ago that did not help. I have one other computer on the LAN, It works great I can renew my lease in seconds, connect to the internet and everything works the same as it always has!!

I have changed the cable and connected straight tho the DSL modem I get the same results everytime.

ANY HELP WOULD BE GREAT
THANK YOU

I am moving this over to networking.

It appears something got damaged in the process. Since you have tried a new adapter and drivers, my guess is it's the Windows configuration.

You need to give some details, like what version/patch level of Windows you're running.

I am running win 98 second edition 4.10.2222a (I believe) I got this from the windows properties general tab. I did do a reinstall of window's without removing win 98 first. (dirty reinstall) It didn't change any thing.

Give this Automated WINSOCK Fix all Windows Versions a try.

Thanks, I tried the autofix utility and it returns a 0 namespace provider removed or renumbered and 0 protical providers removed or renumbered. I still have the same problem.

Any thing else?

Thanks

I found another NIC this time a 3com 3c905c-txm this one works. I guess I just had two bad cards. I should have looked for this one sooner.

Thanks for your promt help johnwill it is much appreciated!!!

You wouldn't normally expect two bad cards, that comes from left field. Glad you figured it out.

Just a thought "I always test the loopback first on cards"

ping 127.0.0.1

jee · 07-30-2005, 10:12 PM

What does that do? Is 127.0.0.1 the card? Pardon me for my lack of knowledge!!!

Thanks again?

127.0.0.1 is an address reserved for the loop back test. when you ping this address you should get a reply. This is because packets sent to this address go down the stack to layer 2 and right back up.

This is to test the NIC card for response and TCP if bounded and working on card.
