A dns problem again?

I sent email to [email protected] but the engineer there said he did not receive it. Also, I did not receive the email he sent to me through his sun.com email. it sounds a dns problem again.
I have changed our mx record to:
@ IN MX junk.domain.com.
before, it was:
@ IN MX junk ==>would this cause dns problems?
Here is the entry in the mail.log which seemed that sun has received my email successfully:
09-Dec-2005 09:39:10.59 tcp_local D 2 [email protected] rfc822;[email protected] [email protected] dns;btmx1.sun.com (relay1.sun.com [IntraStore TurboSendmail] ESMTP Service ready) smtp;250 recipient <[email protected]> OK

Your log shows that Sun did indeed receive your mail.
Sun's mail infrastructure has been under DOS attack for some days. Sometimes that's caused delays of up to several hours for inbound mail to get to us.
We also have had some virus infected systems pounding our servers. More delays.
We do contract with an external company to scan for spam/virus scanning. Those folk historically have lost us some mails, too.
Your MX record isn't likely to make any difference in you sending out mail, but in your ability to receive mails, yes.

MY PROBLEM
I am having a DNS problem with my laptop. It connects normally to th e wifi internet but when i try to surf the net it says "DNS Look up failed"
This problem only occurs when with the internet at my house. whenever i connect elsewhere my computer works normally. My ipod, iphone, tablet and other friends computers work normally when they are connected to my internet. i use dmy neigbours nework a couple of times from my house and it wrks normally.
Also when i turn my laptop on or off i can browse for a few minutes or seconds before it fails again. My skype works like there is no problem
WHAT I HAVE TRIED TO RESOLVE IT
I have tried changing the DNS, i used open DNS and google free DNS and it still didnt make a difference.
I have rebooted router many times, nothing
I have changed my home router, nothing
I backed up my computer, resored everything it to factory setting and put everything back on; still nothing
Run a diagnostics at 'Best buy' and they say nothing is wrong; but i know there is something wrong with the DNS
I have tried different "sudo" type of codes on my comupter from stuff i got online and nothign has proved fruitful yet.
i tried using safari, Google chrome and firefox, all not loading
WHAT DO I DO TO FIX THIS?

You are correct. Syncing should transfer any purchased media, including videos, from your device to your iTunes library provided your computer is authorized for the Apple ID used to make these purchases. You mentioned that you have uninstalled iTunes before, but if you didn't follow this guide exactly, uninstalling iTunes and all of its components in the order specified, it may not have been successful so you should try again: Windows XP or Windows Vista/7.

DNS problems on Lion

Hello,
Ever since I "upgraded" to Lion I have had DNS issues.
I know it's a DNS problem because IP addresses work fine. And I know it's not a browser issue, because I am running 'ping google.com' from the command line.
The symptoms are non-responsive queries to DNS servers, in web browsers or the command line (using ping). Currently I am using google's DNS servers: 8.8.8.8 and 8.8.4.4. I'm absolutely sure that there is nothing wrong with those servers. The request to the DNS servers eventually times out, and then I hit "Refresh" and the page loads fine.
Also, if I recylce the network adapter, e.g.
$ sudo ifconfig en1 down
$ sudo ifconfig en1 up
DNS starts working again, temporarily until the next time. It happens again (randomly, not at regular intervals), I then run the ifconfig down/up again, and DNS works again, and so on.
This started happening when I went to Lion.
Thank you

I have just purchased a brand new Mac Mini Server with Lion Server running. Managed to set up DNS service and 5 zones configured and running fine for 1 to 2 days.
The DNS in Server Admin suddenly stopped loading the information and buttons are all greyed out last night, with no changes made since I was away at work. It keeps getting the same situation as thread starter mentioned. I have tried all possible means but it just stop loading zones information anymore.
I would like to try John's approach but it seems I am unable to get 'root' access to perform those actions. Thus would appreciate some advice on how to proceed forward to resolve the issue.
1. Tried the Directory Utility approach to "Enable Root" but when enter terminal, 'sudo root' does not seem to accept the password I have set. Is there any other means to enable an account to have sufficient access to perform those DNS related resolution steps?
2. Is there any location to obtain a copy of the default named.conf?

Strange DNS problems wrt160n v2

My router worked fine with 60mbit internet, i bumped up to 90mbit, and it worked fine for 2 weeks or so, and then one day my desktop, with a wired connection, started to go nuts with the DNSserver, what screwed up the internet, pages would not load, when i refreshed the page it would load, but 5 or 6 mouseclicks further and the DNS was gone again... i changed everything, all the settings, the utp cable, even Vista had to go, just to be sure.. but nothing worked, except removing the router, but that was no option for my laptop, which was working perfect, never had a bad connection or DNS problems....
I went back to the store with the router and there it worked fine, tested everything, but no problems, i came back home, hooked it up, and the problems where back...
Anybody got a clue, my only idea about this is that the 160n cant cope with the 90mbit,i got p. off and bought myself a wrt320n which works perfect, wired and wireless.

WRT160N does work with 90 Mbit...might be the settings are not proper on the router.
However its great that your were able to resolve the issue by WRT160N...

Time Capsule DNS problem - Complete wipe?

Hi!
I am having a strange DNS problem with my time capsule (4th gen).
With one particular site it doesn't load the start page but random pages of the same domain with always the same pictures.
Setup is following:
Cisco EPC3208 cable modem connected to the time capsule via cable
Troubleshooting so far:
MacBook connected directly to the modem loads the start page of the website -> So it must be a problem with the time capsule
MacBook connected to time capsule via wireless loads the wrong page
MacBook connected to time capsule via cable loads the wrong page
iPhone connected to time capsule loads the wrong page
Rebooting the time capsule did not solve the problem
Uploading the latest firmware again did not solve the problem
Doing a hard reset and importing the previous settings did not solve the problem
Doing a factory reset and setting up time capsule as new device did not solve the problem
Changing the DNS servers from the providers to Google's DNS or to OpenDNS had no change
My thought is that there might be something stuck in the DNS cache of the time capsule. I am quite sure that completely wiping the settings should resolve it. Unfortunately the hard reset did not help nor the factory reset.
Any help is appreciated! I really need that page to my daily work!

We have been hitting this a bit.. I was only in the last couple of days posting in another thread.. do a traceroute from your computer to the site. Do it with TC and without TC.. if it routes wrongly or cannot find the site via the TC, something is wrong.. but I am lost as to what. It isn't dns.. it isn't dns cache.. you can simply use dns on your computer and that would totally bypass the TC. The routing is messed up.. that looks like a different issue. MTU??
Something weird.. but if you cannot find a work around.. the answer is obvious.. replace the TC as the main router.. you can bridge it and use it for backups and wireless. But there is some serious issues going on and the TC frankly is doing poorly.
A decent router is available for $100 or so.. my favourite right now.. Netgear WNDR3800 because it runs decent linux third party firmware like openwrt and gargoyle. These stand head and shoulders above the average firmware in a common garden routers.

Interesting explanation and fix for obscure DNS problems

This blog is a real eye-opener:
*10.5.3 Fixes DNS Problems Plaguing Some Leopard Users*
http://hunter.pairsite.com/blogs/blog20080603.html
Who knew?!
"I had tangled with name lookup issues during early stages of Leopard development, and learned that Leopard changed the way name lookups were made.
"... Some people had been carrying DNS baggage for years with no idea, and this had likely been hampering name lookup operations at some level for a long time, even before 10.5 came along.
"In other cases, it was a major challenge. The average user doesn't know (and probably shouldn't need to know) where their DNS settings are, or what they do. And then consider the common situation of a user with a Mac connected to an Airport connected to a cable modem, with various DHCP leases sprinkled into the mix. In most of those cases, DNS settings are provided far upstream and inherited down through the line. The user may see no DNS settings on the Mac, or it might be using the address of the Airport router. The Airport might contain DNS settings inherited from the cable modem, which it picked up from the ISP through the DHCP lease. The issue then becomes one of figuring out where to purge old DNS settings, if that's even possible, and replacing or overriding them with known good ones (such as from OpenDNS.org). It was a challenge in many cases. Just convincing the user they had a DNS issue was a challenge in some cases!"

I think DNS lookup issues are relatively rare these days and so are perhaps not the obstacle to trouble-free internet access that they used to be in the days when ISPs were less Mac friendly and Apple seemed to have issues with DNS lookups without the network preferences having declared DNS server IPs. Even then, I think much of that was timing, with MacOS flavors at the time being rather more critical than ISPs expected and that Windows tends to be.
Much of the DNS hullabaloo had died out until recently, due to the appearance of active IPv6, which once again seemed have caused timing issues. Thankfully since IPv6 is not much in use yet, it can be switched off in the TCP/IP pane of the appropriate network preference and that seemed to cure DNS lookup issues for those who had them once again.
I've found though, both at work with our commercial T1s, and at home with my (not altogether Mac-friendly) ISP, that DNS has not been an issue sine perhaps the mid MacOS 10.3, or maybe even earlier. And as I found at the time when I had issues at home but not with the same system and configuration at work, it turned out to be the ISP's primary DNS server which was not configured correctly and timed out routinely.
Even with IPv6 still enabled I've not have DNS issues with any Mac for some time, and have not experienced any difference in internet behavior between 10.5.3 and anything prior. Even my iPhone, which had DNS problems if the first DNS IP was the local router, has been behaving correctly since the first firmware update last summer!

Windows 7 VM has DNS Problem When Using Wireless

Hello All,
I've been fighting this virtual machine networking problem for over a week now. If anyone has a well-informed suggestion (not a guess) I would appreciate hearing about it.
Here's the problem in a nutshell and then I'll give more details: I'm running Windows 7 Ultimate (64 bit) as my primary (i.e., host) OS. I'm running Windows 7 Home Professional (32 bit) as the guest OS in "Windows Virtual PC" (note that this is *not* the same as "Virtual PC 2007"). If I configure the VM to use my host's wired Ethernet connection, the guest OS can always see the machines on my local network and can always reach the Internet just fine. On the other hand, if I configure the VM to use only my host's wireless connection then the guest OS can still see machines on my local network but CANNOT reach the Internet, except very intermittently (e.g., for maybe 1-2 minutes every hour or so).
I've tried to anticipate the questions you might ask so here is some additional information:
The computer is a Lenovo W500 laptop running Windows 7 Ultimate, 64-bit. The wireless network adapter is an "Intel WiFi Link 5300 AGN".
My Internet connection is via AT&T DSL using a wire2 wireless modem/router.
I have all the updates from Microsoft and Lenovo for this machine. It is 100% up to date with the latest patches and drivers.
I'm running the 64-bit version (or at least I used the 64 bit installer) of "Windows Virtual PC" which I downloaded from this link.
I am *not* running and I did not download "XP Mode".
When the guest OS loses it's connection to the Internet the following message appears in the Windows Event Log:
"Name resolution for the name address.yahoo.com timed out after none of the configured DNS servers responded."
I am able to ping an external machines outside my network but only if I use the IP address. If I specify the host name it cannot be resolved.
ARE YOU GETTING THE IMPRRESSION THIS IS A DNS PROBLEM??? It looks like I do not have access to a DNS when using the host's wireless connection.
On the host OS, the "Virtual PC Network Filter Driver" *IS* installed and selected under my "Wireless Network Connection Properties" settings.
Below are the results of running ipconfig on the guest OS and then the host OS. Note that I am able to ping 192.168.1.254 from the host OS but not from the guest OS. I think this is the crux of the problem.
Here's what I get from an ipconfig /all executed on the guest OS:

Hello,
I am not very familiar wth Microsoft Security Essentials, but believe that it just makes use of the existing Windows Firewall which is present with the operating system.
To me it is odd that the guest OS reports 192.168.1.254 as the IP address for its gateway and DHCP server yet it cannot access them when pinged. Let's try pinging from host to guest (and vice-versa) and see what happens:
From the host OS at 192.168.1.78, try pinging the guest OS at 192.168.1.75.
Then, from the guest OS at 192.168.1.75, trying ping the host OS at 192.168.1.78.
Is each operating system able to ping each other?
Regards,

The same problem again with HP Simple Pass fingerprint reader after upfrading from Firefox 4 to Firefox 5. I have already installed HPSimPlePass 7.0.74.0 to fix the problem after upgrading to Firefox 4.

I have a HP Pavilion dv6 with a fingerprint reader. I had the same problem as many other people when upgrading to Firefox 4, : I couldn't use the HP Simple Pass to enter a website needing a username and password by just swiping my fingerprint. I fixed the problem by downloading the new HPSimPlePass 7.0.74.0. This fixed the problem and I was very happy. Since upgrading to Firefox 5 I have the same problem again, but I already have the new version of HP Simple Pass. How can this be fixed so that I can use this fingerprint scan feature again, or where can I download Firefox 4 again?

Audio Render Problems Again

I'm having problem again rendering a one hour presentation. If I use Command/R, the dialog box indicates seven or more days. If I highlight the selection I get essentially the same estimated time.
Command/R usually works, but not this time. Audio For Playback is checked.
The DV timeline plays in Quick Time OK.
I desperately need to get this video sent out! I even deleted preferences using the "Preference Manager" program.
David

All of my lecture video series are recorded in LP 16 bit audio. Each lecture is between 1 to 1.5 hr in length. I have successfully completed 10 of the 23.
Each lecture is sent to iMovie HD and then the timeline.mov is placed into FCE. One other time the timeline audio would not render, so I converted it to DV via MPEG Stream Clip and placed it back into FCE. The lecture I'm having trouble with is #11.
As mentioned, usually Command-R will do the trick in 10 minutes or so, not 6 to 10 days.

Have you seen this type of problem before? I think it could be a serious issue for anyone in a similar position.
No; but then, I've not had occasion to use TDM. I've been using firerwire drives for over 10 years, both FW400 and FW800, with no issues except a bit of instability using a B&W G3 machine.
TDM should be safe. Using cautious, manual copying of files from the Target machine to the Host machine should not result in unexpected loss of files or damage to the Target drive's directories. It should behave exactly the same as if it were an external (to the Host) firewire drive.
• I don't suppose there is anything I can do to 'put back' lost items from a separate Time Machine drive which has an up to date backup on it.
There is probably a way to do that - seems to me that's one of the reasons for a Time Machine volume.
On the other hand, if the Time Machine volume is rigidly linked to the now-absent OS on the original drive, there may be no way to effectively access the files in the TM archive.
I know that using a cloned drive would work well in this instance.
I have no experience with Time Machine, so perhaps someone who has will chime in with suggestions.
With the machine in TDM with the other machine, have you tried running Disk Utility to see if you can effect repairs to the drive?

Why am I having update problems again?

When I started Muse today I received a message that there was a new update and did I want to install. I said yes and it proceeded, when complete I received this pop up message:
Title, Adobe AIR - "Intial content could not be loaded for this application. Try re-installing or contacting the publisher for assistance".
But you can't re-install because it shows it's already installed. This happen to me a month ago and I had to un-install Muse & reboot before I could re-install.
Why is this happening? Is there a way I could open up Muse without going through a un-install again. This only happens with Muse updates which occur when starting Muse, other Adobe updates that take place through the Creative Cloud control panel are fine.
I just tried again, same problem

Help Again.
My computer just doesn't like Muse & apparently CC programs. After all this time when starting Muse I have been ignoring the message to update because I'm afraid if I say yes I will have the above problem again. Today I got brave and said yes and Muse would not open again!
So I returned to this site and used the link you gave me before to reinstall Muse, when it finished it told me that there was a newer version 7.4 available and would I like to install it and I said yes, and it seemed to work and opens fine.
I also had a request to install the latest update of Creative Cloud so I said yes. Everything went fine. I got really brave and I noticed that there was a newer version of Muse CC 2014 and I installed it but now that CC and other CC programs tell me I need a sign in with my adobe ID to try a 30 trial, if I press the License This Software button it asks me for a Serial Number. Why can't I open CC programs without a serial number, I am a Creative Cloud member? I have 2 Icons on my desktop, Adobe Muse.exe which works and Adobe Muse CC that tells me I need a serial number.

Snow Leopard and DNS problems

Hi
I read a lot about SL and DNS problems while accessing websites. It seems that you have to put your DNS server in system settings/network so that you don't get the error message "can't connect to the internet' in your browser window. My problem is that I change locations with my mac quite frequently (home, uni etc) so whenever I am a a new location I have to go to the network settings and manually put in the DNS server. Why do I have to do that with SL when it worked completely fine before the upgrade to SL?
Cheers
Martin

That's why I have to put it in manually each time I reconnect the MB at home after I had it at uni. Once back at uni I then have to go into the settings and delete my manually added home DNS server. Right after that the uni DNS server address appears automatically. So I guess that is just how SL now works and I have to live with it, right? However, why do we need a DNS server anyway to connect to the internet. I thought a DNS server just facilitates the connection to websites but I didn't know that it is crucial.
You should really try to figure out why your home router isn't providing you with a DNS server address and fix that. It could be a firmware issue, or it could be as simple as you have things set up so that one must manually be set up in the router, and one is not.
You are also misinformed as to DNS' importance.
DNS is the service that translates names - say "apple.com" - to the IP addresses - say "17.149.160.49" - that your machine needs to be able to connect to any site.
Without being able to resolve names to addresses, you have to manually specify numeric IP addresses for everything - effectively meaning you will be unable to use the Internet.

DNS Problems with WRT54G

2 Nights ago we had storms in the area; next morning wife calls me at work and says that internet connection does not work. Get home and take a look at it. I can connect to router wired or wirelessly, was able to look at the configurations, etc. but when I try to access internet pages I get an error indicating DNS problems.
I have cycled power on cable modem (also Linksys but don't remember model number at the moment) and router. Still had the same problem wired and wirelessly.
I reset the router to factory defaults, connected to it both wired and wirelessly and still had the DNS rpoblems.
I reconfigured the router with my original security settings, connected to it wired and wirelessly and still had the DNS problems.
I connected directly to the cable modem and had no problems accessing internet at all.
Is there any way that I can force the router into updating DNS information? Or possibly reset DNS information?
I have run out of things that I know to try. I hope someone can help.

Usually a DNS problem is caused because the router is not connecting to the Internet properly.
Since you have a cable modem, you can usually leave the WRT54G set to its factory default settings, except that you might need to "Clone the MAC address" of the computer that works when connected to your modem.
Hope this helps.
If you need more help, please do the following:
1) state your ISP
2) state the make and exact model number of your modem (not the WRT54G).
3) Connect your computer, by ethernet cable, directly to your modem (not the WRT54G). Verify that you have a properly working Internet connection, then do the following test:
Go to "Start" > All Programs > Accessories > Command Prompt.
A black DOS box will appear. Type in "ipconfig /all" (with no quotes), then hit the Enter key. Post all of the results, except if your "IP address" does not start with 192, then post only the first 3 digits of it, along with the rest of the info. To copy the info to your post, highlight (select) the info, then use the copy (Ctrl-c) and paste (Ctrl-v) keys.
