Hey, I have a problem.

Dunno if anyone here know anything about networking problems?

I live in a shared house and we have a LAN set up with movies and stuff that we share over the network. I used Media player 11 to share folders and stream to my Xbox and laptop as well as other PCs and consoles on the LAN.

This has all worked fine for years until last night. The PC decided to update itself over night and re-started (I rarely restart this antique of a PC). Since the computer re-booted itself up I have had no network. That is I can’t be seen by any devices connected to the network. I have disabled the firewall completely, tried re-creating a shared network using the wizard, checked all the folders and settings on MP, reset the router and resorted to sacrificing a goat but all to no avail.

Now I can’t watch anything from my library at all (which sucks) but I CAN still stream from my mates devices via my Xbox.

What the hell is going on? :crazy_diz

On your computer go to Control Panel, and then Network and Internet. Then go to View network status and tasks and then go to manage wireless networks (If you have an older OS just look around the control panel for Manage wireless networks). Your network should be there, click on it and press Delete. Now when you search for networks it should appear.

Hope that works, let me know the outcome!

First check your ancient machine can still see the LAN/internet – can it ping other machines on your network, or get an internet website ok? If not, that’s the first issue to fix.

If it can, check your network is set as a home one, not a public or work one. That’ll make sure Windows isn’t firewalling anything it shouldn’t be.

I’m hazy about how WMP11 shares stuff… presumably it acts as a DNLA server? If that isn’t working maybe it’s an option in WMP to turn it back on again. Or you could always try a third party DNLA server to stream stuff from your machine – I hear good things about TVersity.

windows updates especially on XP are notorious for hosing the TCP/IP stack which makes your network work properly. Firstly shut down the PC totally (to power off) and restart it again, just in case not all the updates went through. Then try again.

also what are the OS’s of the other machines? remember that they too would have had updates…

Ah, ok, I don’t seem to have any internet on that machine either. Why would that be then? The little network icon shows me as being connected but I can’t load web pages.

what do you get if you run a command prompt “CMD” and enter “ipconfig” in the window? it should be..

Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:UsersPC02>ipconfig

Windows IP Configuration

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : (removed just in case) you probably won’t be using IPv6 anyway
IPv4 Address. . . . . . . . . . . : 192.168.1.65 (this is your lan address, first 3 numbers should be similar to the router address)
Subnet Mask . . . . . . . . . . . : 255.255.255.0 (normal for a small network)
Default Gateway . . . . . . . . . : 192.168.1.254 (should be address of your router)

if those numbers are anything different from 192.168.n.n or 10.n.n.n or 172.n.n.n (where n is a number from 0-254) or not there at all, something is wrong…

if you do this on one of the working machines this will also show what addressing scheme the router is giving and the address of the router. Routers also often contain a web page you can use to see what is connected on your local network (though don’t monkey around with this if you aren’t confident about what you are doing or you will put your whole house offline…)

Hmm, If I do that the DOS window opens up for a split second and then disappears before I can get a chance to read anything!

go to start menu / run (if on XP) or that bar at the bottom on Win 7 and enter “CMD” – that should give you a proper window. I vaguely remember that on XP there is a useless icon which does just that for command prompts

Ok. yeah that’s better.

Yeah, that looks fine compared to what you posted. So why no net or network?

what IP addresses does it show? (its OK to post the IPv4 addresses as they won’t allow hackers into your network unless they are actually in your house…)

also if you try an open a browser window using the address marked “default gateway”, what do you see? is it the admin page to your router?

How do I open up a browser with the address marked “default gateway”? (Sorry, I’m crap!).

Everything is hard wired (no wifi except my lappy) most other devices are Xbox360s.

Sorry, I’m not being deliberately thick but (whatever this number is)?

The machine is it’s own default gateway? If you’re using a router that’s not right…

Give us the output from “netstat -r”

the other thing I would suggest trying is doing a full shutdown of that PC until the power turns off (installing any remaining updates)

then wait 10 seconds and start it back up again

it should hopefully then send a DHCP request to the router which is where it gets the IP address from and the gateway address (normally that of the router)
