Windows 8.1 DirectAccess DNS-Problems

Hi
We use DirectAccess on Server 2012R2, Win 8 and Win 8.1 Clients (same hardware), force tunneling configured.
We can access our corporate resources (File- and Webservers) without problems.
while the Win 8 clients works great, the Win 8.1 clients make some troubles:
when in DA-Mode (external) the Connection to the file-Server works. After going in standby-mode und back online, the network-drives and the RDP-Sessions can no longer connect (host not found) für about 15 minutes or until i clear the DNS-Cache. In
the corporate Network, the standby-mode does not affect the connectivity or name resolution. Has anyone seen this problem with the win 8.1 clients too?
Thanks, Mario

Hi,
Unfortunately, the available information is not enough to have a clear view of the occurred behavior. Could you provide more information about your environment. For example,the
exact text of any error messages that you received that are associated with this problem?
The server version of the problem on, when you experience this issue what are you trying to do, when this problem occurs the system log record information, screenshots is the best information. And could you clarify “when in DA-Mode (external) the Connection
to the file-Server works. After going in standby-mode und back online” means.
Base on my experience, it maybe is the NRPT policy issue, you can refer the following KB for the further troubleshoot:

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?

Direct Access Server 2012 R2 Single NIC DNS problem with 8.1 Enterprise

Dear helpers,
I am beginning to rip my hair over the following problem and I am asking for some guidance:
I have setup DA on a server 2012 R2 with the simple wizard using one NIC. I have opened up port 443 to my DA Server and operations status is showing green on everything. I have used Djoin to join a remote win 8.1 enterprise client to our domain and
setup DA. I can see that my tunnel is established and the client shows up as an IPHTTPS client on my server:
Role                       : client
URL                        : https://vpn.ourdomain.com:443/IPHTTPS
Last Error Code            : 0x0
Interface Status           : IPHTTPS interface active
Connection status on client is stuck in connecting and the eventlog on client gives me following error:
The system failed to register host (A or AAAA) resource records (RRs) for network adapter
with settings:
           Adapter Name : {424F50B4-BF1A-4D96-81FA-7D7436A99F07}
           Host Name : TEST
           Primary Domain Suffix : ourdomain.com
           DNS server list :
                172.16.8.1
           Sent update to server : <?>
           IP Address(es) :
             172.16.8.110
The reason the system could not register these RRs was because the update request it sent to the DNS server timed out. The most likely cause of this is that the DNS server authoritative for the name it was attempting to register or update is not running at
this time.
I understand why this is failing because it seems like it is contacting the local DNS to register and that's wrong.
Get-DaConnectionStatus gives me the following:
Status    : Error
Substatus : CouldNotContactDirectAccessServer
I can ping the name on the DA server and also the IPv6 address, I can also do nslookup if i set the server used to my internal DNS-servers IPv6 address(DNS and DA server = same machine). My DA Client GPO is being applied to the client and i get an NRPT table
looking as follows:
Settings for DirectAccess-NLS.ourdomain.com
DirectAccess (Certification Authority) :
DirectAccess (IPsec)                    : disabled
DirectAccess (DNS Servers)              :

Settings for vpn.ourdomain.com
DirectAccess (Certification Authority) :
DirectAccess (IPsec)                    : disabled
DirectAccess (DNS Servers)              :
DirectAccess (Proxy Settings)           : Use default browser settings
Settings for .ourdomain.com
DirectAccess (Certification Authority) :
DirectAccess (IPsec)                    : disabled
DirectAccess (DNS Servers)              : fd1f:6801:cc14:3333::1
DirectAccess (Proxy Settings)           : Bypass proxy
I cannot reach any internal resources by name or IPv4 address except the DA server.
I will gladly provide more info if needed
Please help!

Hi,
Thanks for your reply.
Firstly, computer certificates are necessary for DirectAccess.
In addition, it is no need to assign an IPv6 address on all the servers. In Windows server 2012/R2, the
Built-in NAT64 and DNS64 support for accessing IPv4-only resources.
If you select Configure DirectAccess Clients with DNS client suffix search list and add additional suffixes to the list,
you can search for short, unqualified computer names in more than one specified DNS domain.
For more detailed information about DNS suffix search list, please refer to the link below:
Step 2: Configure the DirectAccess Server

I am having a DNS problem with my computer. My laptop connects to the internet and my skype works normally but when i try to surf the web it says "DNS Look up failed".

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.

Windows 8.1 Pro has error while joining domain, while windows 7 pro has no problem to join in the same network

I am having the same issue as posted in http://social.technet.microsoft.com/Forums/windows/en-US/6ea57e5f-6e9d-49bd-9dd7-832ea84c0276/windows-81-pro-will-not-join-domain?forum=w8itpronetworking
There are a few other people have the same issues. However there was no real solution provided although the post was marked as answered. I am posting it here again and hopefully I can get some help to solve this issue.
We got two new PCs, one with windows 7 and the other with windows 8.1 Pro. In the same network with domain, the windows 7 pc has no problem at all to join the domain. However the windows 8.1 Pro won't join the domain. On the windows 8.1 Pro computer,
I can ping the other computers in the network. The error message says:
An Active Directory Domain Controller (AD DC) for the domain "cmi" could not be contacted. ...
In my case, the domain name is "CMI". I am sure the DNS setting is correct. What did I do wrong? Any help is greatly appreciated. Thanks.

I tried the solution in that article.
In HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netlogon\Parameters folder, there is no
NeutralizeNT4Emulator. So I followed the instructions and created one, and set the value to 1. Then I restarted the computer and tried to join the domain again. I got the same error. Below is more from the netsetup log file:

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 is exactly what is happening. The problem with my DHCP server at home is that it doesn't submit the DNS address to the computer somehow. 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.

E4200 STRANGE DNS Problems

Ok so I just purchased the E4200 and upgraded to .03 (newest firmware) and noticed everytime the router reboots my computer (wired client) would say limited or no internet access for some time after the router has stopped blinking. When I try to open Chrome and go to google.com I get a DNS error. If I then try to go to another website like say bing.com it works and then google.com works. Mind this whole time Nslookup works and when I can't seem to access google.com from my wired connection my iPod can connect to it wirelessly. Normal or is everyone else experiancing that? I also suppose if I wait some time while it says limited or no connectivity it will work and switch to internet access.

DNS is one of the most essential services on any Windows network. Active Directory can’t function without DNS, and it’s is also used by any number of other network functions. So it’s critical to troubleshoot DNS problems as fast as possible. So you can try to reduce the LAN card speed. Here is the step:
START--> right-click My Network Places and click Properties
right-click on the device and click properties
Click on the CONFIGURE button
Select the ADVANCED tab and the settings you can alter are listed on the left.
If the issue still persist then here is the link which may help you in resolving the concern: http://www.techrepublic.com/blog/10things/10-tips-for-troubleshooting-dns-problems/1964

SL Losing AD Binding - DNS Problem -

Hi,
Having successfully built our dual boot Mac suite (XP and 10.6) we have had no real issues until yesterday, when to my surprise after restarting all the Macs following a sent Unix command via ARD to set the firmware password they all lost their connection to AD. Directory Utility informing me that the server is not responding.
Now I don't think the firmware password being set caused this issue, and after rebinding a few machines and lots of testing and changing DNS TTL values, host file changes on the Mac and interval time changes for the computer account password I couldn't figure it out.
I restarted the windows server (2003) that DNS resides on (there are two DC's both 2003 with DNS on both replicating) and then restarted all the Macs and they all connected to AD again, even the ones I'd done nothing on. So my investigation moved to the windows server but I can't find anything that looks out of the ordinary.
After trawling through the logs on the Mac again I have noticed the lack of confirmation of the machine successfully registering it's hostname.
When the machine is connecting to AD fine I get log messages saying:
configad[14] setting hostname to "ICTMac07-Aidans.local"
configad[14] network configuration changed
configad[14] setting hostname to "ictmac07-aidans.domainname.org.uk"
com.apple.directoryservices[11] successfully registered hostname with DNS
When the machine is not connecting to AD I get all the messages except the last one: successfully registered hostname with DNS.
Checking the DNS server there is a record for it both in the forward and reverse zones. Restarting the windows server and AD connection resumes.
So does anyone know what might be up on the windows box? Or where I can look on the Mac to find a error message about not registering the hostname as the lack of a message is not much to go on.
Thanks in advance.

I don't know what's causing the problem, but I'm pretty sure the inability to update DNS a side effect of being unable to use AD, not the cause (and so it's not a useful indication of where the actual problem is). Updating DNS is done by the AD connector, via AD itself, so if you can't talk to AD it's going to fail.

HT201364 MacBook Pro has DNS problems. Need to Download new OS, but can't.

I need to download on another computer since my I can't download from my MacBook, but I only have one old desktop with not enough space or a Windows laptop. I want to download it onto a thumb drive on one of those machines. How can I do that?

It would make a lot more sense to fix the "DNS problems," whatever they are, but if for some reason you can't do that, and you also can't free up about 5 GB of space on your other Mac (which doesn't have "DNS problems"?), then you'll have to install OS X on an external drive, boot from it, and then download the Mavericks installer. You can't download it directly to a secondary volume.

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!

Strange DNS problems

I have been seeing very strange DNS problems running 10.4.7 on my MacBook Pro.
I travel a fair amount, and in certain places, I have problems with DNS. I will Google a topic for example, and I will get a response that "www.google.com" cannot be found.
Simply refreshing the page will many times cause the request to "take".
This does not happen under Windows XP (I am converting from XP and actually am carrying two laptops) from the same hotel room, using the same hardwire Ethernet connection.
It also doesn't happen using an XP install under Parallels.
Not sure where to go from here - I have done a DCHP "renew" from within the hotel room - no help.
Note that this doesn't happen everywhere. Today I happen be a stone's throw from Apple HQ in Cupertino, and I am getting it like crazy.l
Any ideas what to look for?

I can hopefully add a little more background to this being on the network end of things.
First, a little background:
I work at a hotel and we provide free wireless (a/b/g) and 100 Mbps wired to each of the guest rooms. For a long time we would receive a large number of support calls from guests whose laptops were configured to use a static IP address in an office environment rather than DHCP. We'd have to walk them through changing their network settings to DHCP, which can be very difficult with most computer users who have no idea what any of that means.
To solve this problem we purchased a Nomadix AG5000 (http://www.nomadix.com/products/platforms/ag5000/), which essentially ignores everything the computer provides for its network settings (identifying it solely by its MAC address) and gives it a DHCP address from our pool. We use the 172.16.0.0/16 range, which also avoids the majority of VPN problems related to NATting. This device is used in a large number of publicly available networks for just this reason.
This is when our problems started. Windows computers it seems have no problem with this kind of configuration, static IP already configured or no. Mac computers do. When they first connect, they'll often have trouble resolving anything but start to after a couple refreshes. The longer they're connected, the better they get at being able to resolve things and it eventually mostly disappears.
I can fairly reliably duplicate this problem with my Powerbook and I've deliberately placed myself on a VLAN separate from the Nomadix box for this reason.
Other than reloading a bunch, I have not yet figured out a solution to this problem that does not require manually doing everything DHCP is supposed to automate.

If GTA IV believes the system is under specification even though the computer is powerful enough to run the game with higher settings, the following will fix this problem.
This will work if your problem looks like this: "resource usage 230/60" and you can't change any other setting
Just follow the steps:
Step 1: Create a text file named ‘commandline.txt’ (without the " ")
Step 2: Put the following statement inside it:
i5 users: -availablevidmem 18.0 (with the -)
i7 users: -availablevidmem 22.0 (with the -)
Step 3: Open the main GTAIV folder (C/ program files (86)/ rockstar games/ GTA IV) and copy the commandline.txt file into it.
Step 4: locate the file "GTAIV.exe" (in GTA main folder)
Right click the file and select Properties
Under the shortcut tab, you will see an area that says Target
Modify the Target adding the command line after the last quotation mark (just add the statement you added in commandline.txt)
(remember, i5 users: -availablevidmem 18.0 / i7 users: -availablevidmem 22.0)
It should look something like this:
Make sure to add space between " and -"
I hope This helps, although late cx

Contact your support personnel or package vendor. I am using windows XP 32 bit, all the other computers in my house downloaded just fine, no problems, however this is the computer my iphone is set up to, ive tried doing a virus scan, windows update, downloading other things, updating everything possible, everything works fine, its just itunes that wont download, anyone have any other ideas?

Yes, I had found a similar solution also. I'm running XP Pro, SP3. I went Control Panels/ Add-Remove programmes/apple software update/ change/ repair. Then run the 10.5 exe.
While the programme updated from version 8 of iTunes, my new iTunes is now a mess. Not all of my music was in the same folder previously but it all showed up on iTunes. Now many albums have been left out, some have only a few tracks and some have two copies of some tracks as well as having other tracks missing. I haven't begun to work on that.

I currently have an old version of Photoshop Elements, it is version 5.0. I recently upgraded from my old Windows XP computer to a new Windows 7 computer. My question is: Can I install this version 5.0 on my new windows 7 computer without any problems?

Do not know about 5, but, just installed PE 6 on I7 64 bit and it works.

Does anybody know if Windows 8 is causing a problem with iTunes? Many songs on my old iPod are now missing in my iTunes library and I can't find them anywhere. Also, I have a new iPod and am afraid of using it for fear of something else going wrong.

Try assigning Queen as the Album Artist on the compilations in iTunes on your computer.
