I had the PSU fail on my PC, was working perfectly one evening, would not start the next day. Anyway I have replaced the PSU and it is working just fine again except... I cannot now access the internet via Web browser. Outlook e-mail is fine, I can ping the DNS servers OK.

My connection is via a D-Link router which is working just fine as I am accessing the internet on my wifes's's laptop wirelessly using the same router.

When I click on Firefox I get the message.

The connection to the server was reset while the page was being loaded
The network link was interrupted while negotiating a connection.

Not hugely helpful!

Using IE I get the standard page not available message, but if I run the XP network check it shows these messages
Windows cannot connect using HTTP, HTPS or FTP
Check the firewall settings for HTTP (Port80) HTTPS Port (Port 443) and FTP (Port 21)

I use Black Ice firewall software, but turning it off completely does not make any difference so I don't think the problem lies with the firewall.

Any suggestions please?

Go to start>run>type "cmd" without quotes and hit enter>type "ipconfig /all" without quotes and hit enter>copy and paste all the stuff that that comes up with here, that's a good place to start to check settings etc.

Is this a home system? because it's very unusual to have your own DNS server, this is most likely the problem. I think DNS servers are provided by your ISP (is that right serverguy? I'm still in the process of learning some of this) did you get any setup documentation from your ISP when you joined them? if you did, try looking through there to see if it mentions what DNS server your meant to use.

The DNS address is that of the router, I think - but cannot be sure - that it has always looked like that when it was working.

The DNS addresses are set up in the router.

ipconfig for this laptop which does work is basically the same just a different ip address for the pc.

[thingie2]

ok, that isn't the problem, I didn't think own DNS servers were very common (I'm sure i heard or read that somewhere, but not 100% sure about it). Do you have any permission restrictions available on the router? If you do, check those, make sure that IP address/MAC address (physical address) is allowed.

Also, try pinging www.google.co.uk, see if that manages anything.

[baxlobs]

I can't imagine that anything has changed in the router, for 2 reasons.
1) this PC connects thru same router,
2) The other PC can access my ISP e-mail server with no problem, if the MAC address was blocked it wouldn't let that thru? Unless it could somehow just block HTTP and FTP and not SMTP?

[thingie2]

That is possible, it depends which ports are allowed access, that would also be something worth checking, check that port 80 (HTTP) is allowed from that computer, I don't know why it would suddenly decide to block it, but it's something worth checking. And did you try pinging?

[baxlobs]

Yes I tried pinging google and it worked fine, so DNS is functional.

I haven't yet managed to check the router settings, may have time tomorrow.
