Internet connection

By RCOM ·
I inherited and am working on a simple peer network with 6 PCs that share a few folders and printers all have Win98. There's one system that won't connect to the internet.
The hard drive was transferred from another PC and since then there's no internet. The company did have the Klez virus but that was taken care of and again the other 5 systems connect. The virus software was manually removed and reinstalled.
The connection is DSL with Cisco 678 router, TCP/IP, DNS and Gateway checked to becorrect or matching other systems. Changed settings to that of another working PC, no go. The PC can connect to the LAN and access all shares. The others can see this one too. Originally there was nic installed so took it out and used onboard nic. Removed all networking components, and IE6. Reinstalled networking no go.
Reinstalled win98.
Ran winipcfg tried releasing and restarting all. Can ping router but not past. IE settings check and home page for all PCs set the same. Ran file checker and there was one file that was changed or corrupt extracted that.

I'm going to try a fresh install of win98 in another folder to see if it connects. Because of the software installed It's not an option to format and start the system over and don'tthink it's needed.

Final (dumb) question is there any way that the router will not allow the MAC address of this nic?

Any help or suggestions?

It sounds like you've done everything you should to check the settings. One thing that you did not mention was where the pc is getting its ip address from. Is the Cisco router providing dhcp services and handing out ip addresses or are you assigningthem manually to the workstations?

Is the ip address of the troublesome pc in the same grouping as your other pcs (ie 192.168.0.x) and is the subnet mask the exact same (ie 255.255.255.0)?

Do the ie connection settings match. Check Tools->Internet Options->Connections->Lan Settings (normally you'll want all checkboxes cleared).

The answer to your last question is maybe. I'm not familiar with the Cisco router but many routers do allow you to filter or block various users through the router. Check your router documentation or log into the router and check the configuration.

One last question: is tcpip the only protocol you're using or do you have other protocols installed too? If you've reinstalled windows already I believe that it installs multiple protocols by default. If so, and you're not using them, remove them.

Let us know what happens.

DHCP is not in use. TCP/IP addressing used just so happens to be 192.168.0.X, with same subnet. I didn't set the network up but find that the gateway which is 192.168.0.254 unusual since normally it's the first IP address in the range. I wondered if that limits the amount of IP addresses that can be used and if the ISP would do this to sell static IPs. Don't think so. The PC used to connect before the hard drive was transferred so I don't think this is the problem.

All settings for IE are the same as other computers.

As far as my last question soon after posting I realized that the changed nic card has a different MAC address so that's not a possiblity and was a dumb question. :)

In response to your last question, TCP/IP is theonly protocol in use. Once the network and winsock have been installed, windows setup will pretty much reload the same settings. The only difference is the nic'c IP and gateway settings will be gone. The DNS info is still there.

Another thing that I tried was totally removing IE6, all network components and dialup, edited the registry to remove all winsock, vxd and other related settings. This gives you a fresh winsock2. Microsoft has an article on how to do this. Its worked before in simular situations.

Thanks for responsing. Wish there was a way to give credit without closing the qeustion.

Qustion: What's the ip address of the gateway (192.168.0.x also)?

If you read my comment to the first question it's listed there.

192.168.0.254

I don't think it's a problem but does having this high of a gateway effect the amount of IP addresses that are allowed.

Have you checked your Cisco documentation ? It seems that everything is normal, and that you have run through all the possibilities.

Question left whether the Cisco have been configured to allow certain MACs ?

That was my question but I did remove an installed nic card and enabled the onboard one. Both instances resulted in non connection. I yhink the original tech must have installed the other nic card after noy being able to connect.

Sorry, I read it but it didn't take. Since you have tried everything else, have you tried changing ports on your switch/hub that the offending pc is on. I don't think that this would be the problem but... I have had a similar problem on a 3com switch that was finally narrowed down to the port (no thanks to 3com).

As far as the ip being 192.168.0.254 this shouldn't be a problem (as evidenced by all of the other mahcines not having a problem). You can set the last octet to any value from 1 to 254.

Are we having fun yet?

From the same school, even though I know it's not the cause, I've tested patch cables at both ends, moved the PC to a known working location. The thing that's puzzling is the LAN works.

I've rarely seen the gateway set to the highest number, I'm just wondering if that limits the amount of addresses that can be used. Simple to change the router's IP and see what happens, just don't want to mess up the other PCs. This sounds silly to me but this is one of those strange situations.
This place buys and sells used computers so I may just transfer the drive to another PC.

A lot of the folks that post here are so quick to format for almost any problem, I rarely do this. I want to know what's wrong, enjoy the challenge and thefeeling of sucess turns me on.

"ME so horny"

Have a few things I'm going to try today, I'll post if problem found.

Sorry to reject, it's just the way this is set up.

Thanks for response!

Have you tried going to a command prompt and running c:\route print

If not give that a shot - there may be a bad route statment on the computer that is prohibiting it from moving beyond the router.

Nothing unusual that I could see all that shows is from the lan and router.
