Hi guys,

Bryce here from New Zealand. I am new here, and arrived due to reading information on Google about a problem I am having with my machine.

I have renewed all pages on a website, and when I browse to it, I am still getting the old home page. My hosting provider told me to flush DNS on the local cache, and as I am completely "green" when it comes to doing these things, I tried to run cmd from the command function on XP Pro. (start>run>cmd)

So what happens is that the dos screen appears for like a second and then disappears. If I repeat the process immediately afterwards, I can then see the dos screen for longer but I can't type anything into the screen.

Information I read on this indicated that I may have a virus (trojan) in one of the files, so I did everything to check this. I looked for a dump of .com files in system32, found nothing. Searched for the same using search feature and still nothing. I then downloaded 3 antimalware programs and ran them, (4 hours) and although some issues were detected and quarantined, nothing changed the outcome when running the cmd command.

I then found details on a batch file workaround so I tried that. It again bought up the dos screen, but would not allow me to type anything into it, and the batch process did not run. The screen sat idle, with the cursor flashing.

Everything else on my PC is working fine, its just that I want to be able to see the new pages on the website I have changed. I DO NOT have my original XP discs and don't know what else to try.

Can anybody suggest anything that may fix this issue?

Thank you in advance for any assistance.
Bryce

Log on as an administrator, go Start > Run and type: "cmd". In the window that appears type: "netsh winsock reset". When the program is finished, you will receive the message: "Successfully reset the Winsock Catalog. You must restart the machine in order to complete the reset." Close the command box and reboot your computer.

Go Start > Run > type: "cmd" In the window that appears type: "ipconfig /flushdns". Close the command box.

Go Start > Control Panel > Network Connections. Right click on your default connection, usually Local Area Connection or Dial-up Connection if you are using Dial-up, and and choose Properties. Double-click on the Internet Protocol (TCP/IP) item. Select the radio button that says "Obtain DNS servers automatically". Reboot.

Warning: Some Internet Service Providers need specific DNS settings. You need to make sure that you know if such DNS settings are required before you make this change.

Hi there Budapest,

Thanks for your super quick response, much appreciated.

1. I am logged on as administrator.
2. cmd will not run from the start>run method. I get the black dos screen for about 2 seconds and then it disappears.
3. Can't type anything into the dos screen - cursor is flashing but can't enter text
4. I can run regedit.exe and other commands - just not the cmd command
5. I did however check the network connection and it is already set to your recommendation.

Thanks for the help though, I really do appreciate it! Any other ideas would be greatly appreciated. :thumbsup:

Try the fix at Kelly's Korner.

Lift Restrictions - TM, Regedit and CMD - #275 on the left.

Right click on it and save the .vbs file to your desktop. Then, double click on the file icon (on your desktop) to run the script. You may need to reboot your computer for the changes to take affect.

With any fix like this you should create a new restore point and backup the registry first. For backing up the registry I like to use ERUNT.

Thanks again Budapest, I will try that.

I was actually just at Kellys Korner because I saw somewhere that he suggested reinstalling the cmd file. The problem was that the one he had on the site was 4 years older than the one I have on the machine.

I also just tried setting up a new user and accessing cmd through the start>run menu, and that didn't work either. I will try this new recommendation now and see what happens, keeping the fingers crossed of course. :thumbsup:

How to Use SFC.EXE to Repair System Files



Yep its me again, and completed this. Ran through the entire process, it did not ask for any CD, and then it shut off. I rebooted the computer - same problem!

I am starting to get fed up wit this now, lol. I did head over to Microsoft Updates as suggested, and when I typed that in the address bar, a sponsored link appeared at the top of the screen, for a product called "regcure" - anybody heard of this product before?

Still appreciating the help with this issue. Thanks!

Yet again Budapest, thanks for the help, but "no threats found" using the Kaspersky tool.

I have a question.... The only reason I am wanting this "cmd" process to run is that I was told to complete a DNS Flush on my computer. My Hosting Provider told me this because when I deleted all files from my main hosting account in preparation for a new install, I browsed to the domain and was still seeing the "old" (deleted) index page on the screen.

When I use the proxy "pagewash" (www.pagewash.com) I see the "new" index file created by Wordpress. However after clearing my cache and revisiting the site with my PC, I still see the old file.

Maybe there is another way of fixing this issue without needing to use the cmd app, and then conducting the dnsflush command??

Also, as a last resort, what would happen if I changed the nameservers to something new? Do you think that would overcome the problem??

Thanks again, you guys are extremely helpful.

Bryce

p.s If I direct the browser to mydomain/index.html I get the same "old" page which is no longer on the server. If I rename the file and point the browser to mydomain/index1.html I see the new file.

Hi Grinler,

domain is http://www.aceslegacy.com

Not sure what you mean by "new ip address" - if you could emphasize on that I can see what I can find out :thumbsup:

Thanks for the input

allwinners,

Do you have a new ip address for that domain or do you have the same ip. Think he wanted to know that if i am interpreting his post correctly. A IP address is a number ( for example 192.168.0.1) to identify computers and websites on the web.

Thanks for the clarification coxchris,

The domain has been up and running for like 3 years, and as far as I know the IP address is the same as it always has been. I thought the IP address was attached to my computer though and not the domain!? This is where I get confused, lol.

edit: Just checked the original sale invoice and the domain IP Address is the same as the original. I used http://www.hcidata.info/host2ip.cgi to search the current IP address, and the original was sent to me by email in May 2008. The IP Address is 74.54.219.82

Thanks
Bryce

Is that your updated site?

Also what DNS IP's are you using? Are you using OpenDNS or your ISP's?

When trying to run CMD via Start do you get any error messages?

Also try this: Start > All Programs > Accessories > Command Prompt

What does that yield?
