A few days ago, a buddy of mine and I decided to start a webpage and a related forum. A friend of my wife's hosts these things so I set up an account with him. Within a couple of days, we were up and running. The host (my wife's friend) told me that he was switching to a larger server. From that point on, I have been unable to access the website or the related forum from my home computer. My computer runs Windows XP and has a Comcast cable internet connection. Everyone else I have asked is able to access the website and related forum, (it is listed as my webpage). I can access any other internet site from my computer. The only non-working combination is the website / forum and my home computer. The host doesn't have a clue right now and I asked my IT department at work and they were stumped. Hopefully someone here as a clue.

Disclaimer: This is my first post, so I apologize if it is listed in the wrong forum or was inappropriately posted.

Can you access it from work? Try flushing your internet cache (temporary files) and also the dns cache. To do the latter go to the command prompt and type ipconfig /flushdns and see if you can connect. Welcome to WD. Cheers

Thanks for the welcome and the reply. Yes, I can access it from work just fine. I did the flush on request of the host. Didn't work. He has a theory that it is on Comcast's end and that the IP address is not in their router tables. He gave me another web address that has the same IP address and sits on the same server and I was unable to access it either. I have emailed Comcast and waiting to see what their response is. If they say it isn't them, then I may try siging up for a $5.00 / one month of dial up connection and if that works I may be in the market for a new internet service provider. :rolleyes:

it could very well be that the domain has not propogated to the comcast dns servers yet (what he meant when he said it wasnt' in their router table :rolleyes:) Anyways wait for the response from comcast as I'm sure that they will get around to it eventually. Also when you ping your website does it get the same address at work as it does at home or do you get the ip of the old server? If they are different then you can manually add the ip you get from work to your lhosts file (I think thats what it's called in windows) pointing to that domain. Yes it should work the other way but it's a workaround for now. Cheers.

1st, welcome to windrivers.

2nd best way to see whether it's comcast or you, is to ask someone who has comcast to access your site.

check if you have anytype of firewall or filtering program that could possibly blocking access to the webserver from your pc.

Along a similar line: There's one site that my desktop computer can't get to, but my laptop can......while they're sitting right next to each other, going through the same router and cable modem..... :confused:

when you ping it from both stations does the ip match? Try a ipconfig /flushdns on the lappie and see if that fixes it. You might try clearing the browser cache too.

Have you tried putting in the actual IP address in the web browser ?

Now adays that doesn't work all the time what with shared hosting and all. Depends on the site.

Open a command prompt and try to ping the site address (www.blurby.com) to see if DNS is resolving it to IP.

1. If it does bring up an IP and can ping it, it's not comcast DNS.
2. If it does not bring up an IP then it is comcasts DNS servers.
3. If it brings up an IP but can't ping it it's not comcast DNS but something else blocking you.

One thing to try if it's #3 is a traceroute and see where the signal dies, that's probably you're point of failure.

I will try and answer in my best computer illiterate way. Was on the phone with comcast tonight. I did a trace and a ping. Basically both get stopped at the host site ev1. The ping simply reaches the site but then is turned away for some reason. The comcast technician stated it was on the ev1 side but did agree with my "broker" host that it is a problem with the router tables. On the ping I could follow where it went until it eventually hit ev1 and timed out. The CT then had me go to www.accu.org. On there is a link for the visually impaired. He had me access the site through what he described as a tunnel. From my limited understanding, I basically switched from comcast to accu then entered the website through accu. The only problem with doing it this way is that what comes up is bare minimum, i.e. a site made for the visually impaired. The CT told me to contact my broker host and to see if he couldn't get it resolved with ev.1

Okay, at least win I access through accu I now have found how to disable the visually impaired section so that I can access the site.

Also, thanks for all the great responses thus far. I will certainly post an update once this is all figured out. Please keep the great advice coming. :thumbs2:

If it is a shared host they could have your ip blocked because it was used for spam by somebody else (ahhh isn't dynamic ip wonderful!) Check with your host and see if this is the case. I'm not real sure if you can but you could also try a release renew from your router to see if it will dish a new ip but I kind of doubt it. Worth a shot anyways. Cheers.

I just wanted to give everyone an update. It was not comcast but for some reason evo was blocking my address. I wasn't really told why but the host had it unblocked for me and I can access the site fine.
