Question DNS Timeout errors with jeopardylane.com
I'm online with Wanadoo Anytime in the UK (dial-up connection) and I own www.jeopardylane.com which I bought through www.1websitehosting.biz and is hosted (I think) by www.drs-servers.com. Ever since jeopardylane.com moved servers in November I've often had difficulties accessing the website and its mail server because of DNS_TIMEOUT errors. These aren't linked - sometimes I can get to both the site and mail server, sometimes neither, and sometimes just one or the other.

Having asked a few people, I found this only affected those whose ISP is Wanadoo (formerly Freeserve). I e-mailed Wanadoo about it and received the following reply:

Quote:
Thank you for your email.

From further investigation i have discovered that the setup of the site
is the reason a Wanadoo connection gives you the error. If a website is
not RFC compliant then it will not be displayed by Wanadoo. Please refer
the owners of the website to www.dnsreport.com. If they search for
www.jeopardylane.com they will see the problems. Until these problems
are rectified the page will not display.


So, I forwarded the e-mail from Wanadoo to 1 Website Hosting and got the following reply:

Quote:
I have passed your email to our support to look at but I have tested your
site from a bt connection and the only failure was from the name servers,
which are set not to respond to ICMP ping packets, this is normal.

The warnings on the others will not affect the site being viewable, if you
read the legend at the bottom of the site it says the following :

Rows with a WARN indicate a possible minor problem, which often is not worth
pursuing.


If it's normal for the name servers to not respond to ICMP ping packets, why does 207.44.193.1 not do it but 207.44.192.91 does? 207.44.193.1 does not respond when queried for the SOA record or version number while 207.44.192.91 does either. I e-mailed the hosting company to ask this question but got no reply.

I e-mailed them again last week to ask if there had been any progress, and got an automated reply saying that they are moving support from email to a web based help desk system. No problem, I posted the Wanadoo e-mail again on there and started again, while also asking if 207.44.193.1 could be the problem. My reply yesterday was:

Quote:
Our server support are still investigating this issue


Oh well.

I'm at my wit's end - can any of the knowledgeable people who frequent this forum please point me in the right direction as to what I should be doing?

Thanks very much.

Well if it really is dns related problems then yeah, I can help. The next time a site doesn't work, I want you to execute the following command at the DOS prompt:

nslookup www.thesitethatdoesnotwork.com

Then paste for me the results. That way I can verify whether or not it is a DNS related problem and what sort of problem it is.

Because I'm using Windows 98SE I don't have nslookup so I used the nslook utility from www.pcpitstop.com, will that do the job?

Right now, when I try to access www.jeopardylane.com in Internet Explorer I get the following error:

Quote:
Gateway Timeout
The following error occurred:
[code=DNS_TIMEOUT] A DNS lookup error occurred because the request timed out during the lookup.



I opened a DOS prompt and typed 'nslook www.jeopardylane.com' and got the following result:

jeopardylane.com 207.44.192.91

Meanwhile, Outlook Express cannot access my e-mail and fails with this error:

The host 'mail.jeopardylane.com' could not be found. Please verify that you have entered the server name correctly. Account: 'webmaster@jeopardylane.com', Server: 'mail.jeopardylane.com', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 11001, Error Number: 0x800CCC0D

However, if I type "http://jeopardylane.com" into Internet Explorer instead of "http://www.jeopardylane.com" the site appears.

Does any of that help at all?

I don't know anything about nslook utility. I don't know if it's using your system, your resolver list, or directly resolving the domain. So let's use ping instead.

ping www.jeopardylane.com
ping jeopardylane.com

Show me the response. Don't just tell me if it timed out or not, I want to see the actual response exactly. Then, since your problem is intermittant, make sure the www doesn't work and the root works still in IE.

Everything's working fine at the moment (typical!) but in case it's of any importance, I just realised I'd entered jeopardylane.com as 207.44.192.91 in my HOSTS file previously, hoping it might cure the problem on my machine (it didn't). I've deleted the HOSTS file now so it won't affect any further results.

It hasn't happened again yet where www.jeopardylane.com fails and jeopardylane.com works, but right now neither are accessible, nor the mail server.

I tried these commands, and the responses are shown below.

nslook www.jeopardylane.com - Unknown host www.jeopardylane.com
nslook jeopardylane.com - Unknown host jeopardylane.com
ping www.jeopardylane.com - Unknown host www.jeopardylane.com.
ping jeopardylane.com - Unknown host jeopardylane.com.

Could the situation where www.jeopardylane.com failed but jeopardylane.com worked be down to the HOSTS file that I've since deleted?

If www.jeopardylane.com is failing in IE, but ping seems to find it just fine and also jeopardylane.com works in IE, then the problem is most likely a misconfigured webserver.

Yes, I think it's a combination of things. The webserver is probably misconfigured as scorpion says. ping was able to get the IP for both the root and www domains. At that point it couldn't be a DNS problem.

However, then you used nslook and got unknown host errors. I wish you had shown me the pings instead. Currently the domain is hosted on 2 servers. One of them is down as of this post. Perhaps the other one occasionally drops as well, or perhaps nslook is just a dumby and wasn't trying both servers when its first attempt (the down server) failed.

How do you mean? When I used ping, I was getting exactly the same message as I posted - "Unknown host jeopardylane.com".

Thanks for all your help so far, it's given me some hope at least!

Well if ping is also returning unknown host, that is when you should use the hosts file to assign the domain the IP. If that fixes ping resolution, but the ping results time out and you can't browse the site, it's cause the site is down. Nothing you can do about that except complain to them.

This is odd... Both www.jeopardylane.com and jeopardylane.com aren't working in Internet Explorer at the moment and nslook and ping gave "Unknown host jeopardylane.com" for both addresses. I put jeopardylane.com as 207.44.192.91 in my hosts file, and:

nslook jeopardylane.com: jeopardylane.com 207.44.192.91
nslook www.jeopardylane.com: Unknown host www.jeopardylane.com

ping jeopardylane.com:

ping www.jeopardylane.com:

And yet still neither www.jeopardylane.com or jeopardylane.com works in Internet Explorer, despite jeopardylane.com pinging correctly...

SilentRage - Basically, I did as you said and used the HOSTS file to assign the IP, and once I'd done that, 'ping jeopardylane.com' worked fine (i.e. it didn't timeout). The site still didn't work though, and neither did 'ping www.jeopardylane.com' (Unknown host www.jeopardylane.com).

Do you have any further ideas? Does it still look like a misconfigured server?

yep very mysterious. Ok, so I'm doing you and myself a favor here. I can't guarantee that when it works for me it isn't working for you without having some means of checking both locations in real time rather than through posts that takes ages to get noticed and read.

So here's a little script
