I have 5 computers connected via e-net hub to internet...two macs, 3 Windows machines. All was fine until two days ago...machine running Windows NT stopped being able to connect vie IE, Morpheus, etc. I do NOT get email on this machine, so I don't think it's a virus and NAV is up to date (except as of two days ago). Other machines on the network connect to net and get email with no problem. They can also connect to the NT machine--i.e., I can share files, etc. with the machine which won?t connect to the ?net.

I've checked the e-net cable...it's plugged in to computer and e-net hub. Idiot light on hub indicates it?s connected...and, on back of Windows NT machine there's flickering green light next to where e-net cable goes in, which I associate with packet traffic (maybe it's just from the other machines).

Anyway, I can't connect and am stumped. Somewhat new to Windows, having used Macs for years. My laptop running XP connects fine, as does another, older PC running NT.

Any help greatly, greatly appreciated.

Does it have an IP address? If so, where (maybe a router) did it come from? Are other computers connecting TCP/IP or other protocol?

by winmorgan

All other computers connect via TCP/IP as this one is also set to do. It WAS doing so until last weekend, that's what has me baffled.

Try installing the NetBeui Protocol on that computer and see if it works. Without NetBeui I can see my other computers on the network but it won't connect to the internet. I installed the NetBeui protocol and then it connected.

by winmorgan

NetBEUI IS installed on it, as it is on the others (the Windows machines, that is), and all components are in place, AND it worked until last weekend which is what has me baffled.

Do an IPCONFIG /ALL on the NT machine to see what it's address currently is. Then try doing a release/renew on the IP address to see if the machine gets a new IP or is issued the same one it had before. Could be a possible conflict with one of your other PCs.

If that doesn't work, try removing the PC from the workgroup/domain, reboot the PC, and then re-add it.

If all else fails, remove networking software, reboot, and re-install networking.

Hope this helps.

Like the others here I suggest you open a DOS window(Start>Run> type: Command > OK) and check your IP address. If I understand you correctly you have a cable or dsl internet service and have it connected to an uplink port on you hub (or a x-over cable on another port...) and then hook up your machines to this hub and have them get IP address automatically. If this is indeed your hook up it may possible your provider has changed its policy on IP addresses. Having 5 machines connected this wayyou are getting 5 IP addresses from your provider. Alot of providers are starting to charge for additional IP addresses. If you are not getting an ip address or just getting a generic windows assigned ip (the NT machine should have a similar ip your other machines...) then this may be your problem. Give your provider a call and ask. If this is your problem you either have to pay for additional IP or go with a Proxy and/or router solution. Hope this helps.

Also try turning of the other machines and see if the NT machine can access the internet then.

First, thank you. Second, I considered what you said about being charged for additional IP addresses, but that doesn't seem to be the case (I checked). Also, the Windows 2000 (mistakenly previously described as Windows NT) is now connecting again, after about a week of not connecting. BUT...I'm adding this comment to ask you a question. YOur said: "Give your provider a call and ask. If this is your problem you either have to pay for additional IP or go with a Proxy and/or router solution" What I want to ask is if you can tell me how I'd find out about how to use both of those solutions if I need to in the future? i.e., how do I "go with a Proxy," and/or a "router" solution?

I'm closing this with an "unfavorable" rating just so you'll get this comment. I close it with favorable the next time, and I thank you for your help.

Best regards,

Win

Probably the easiest thing to do is head to best buy and buy a small router. The linksys cable/dsl ethernet routers are a popular choce for ease of use. Check out linksys.com and look for part no (BEFSR41). The router should have all the information you need to set it up as a DHCP server and effectively avoiding paying for extra IP addresses from you provider. Also, I think I get a email notification when ever an answer is rated any way...not 100% sure though. Good luck and I am glad your system is connected again!
