K9VGM - network adapter occasionally failing

Hi friends,
I have a new computer based on a K9VGM board. Everything is running fine until after some random number of hours - between 6 - 80 hours, when the network adapter (on the motherboard) suddenly fails. It may have to do with the network load, but it doesn't seem to be related to the temperature in the room.
When it fails, everything else on the machine is running fine, except for the network adapter. I can't control it all from inside windows, any "disable" or "repair" on the network connection or network adapter fails, and the window just sits there. It seems like the OS can't communicate with this piece of hardware at all. After a reboot the computer runs fine again, until it happens the next time.
This is actually my second K9VGM motherboard in this machine - I returned the first one to the reseller, with this error. They supposedly tested it, and confirmed the problem, and sent me a new one - which has the same problem...
All drivers and updates should be applied, according to the MSI live update tool.
Any tips on ho wto proceed? I am not so keen on sending it back again, to receive another MB with the same issue. I am tempted to just buy a cheap NIC PCI card and put in the box...

I have held off on doing anything on this - and now the machine has actually been running without any network problems for more than a week - so maybe it was just the previous board that was faulty, and the new one had a temporary hiccup (not reoccuring problems).

Server 2012 R2 - The system failed to register host (A or AAAA) resource records (RRs) for network adapter

We seem to be having an issue recently after introducing new Windows Server 2012 R2 servers where they fail to register DNS correctly. The Windows Firewall is off and the servers are on the same VLAN with no firewalls between them.
When I do an ipconfig /registerdns or wait 24 hours for the system to try we get the following error:
The system failed to register host (A or AAAA) resource records (RRs) for network adapter
with settings:
Adapter Name : {4A0ECF05-193F-4BEA-AA46-BEC593BA752B}
Host Name : SRV-DATA
Primary Domain Suffix : internal.local
DNS server list :
192.168.0.50, 192.168.0.42
Sent update to server : <?>
IP Address(es) :
192.168.0.99
The reason the system could not register these RRs was because the DNS server contacted refused the update request. The reasons for this might be (a) you are not allowed to update the specified DNS domain name, or (b) because the DNS server authoritative
for this name does not support the DNS dynamic update protocol.
To register the DNS host (A or AAAA) resource records using the specific DNS domain name and IP addresses for this adapter, contact your DNS server or network systems administrator.
On our DNS server we have set for the internal.local zone Secure Updates only so that looks good because it is Active Directory that should be handling this authentication to update the record I assume. Just to mention that when also doing an ipconfig /regsiterdns
the update fails within a few seconds.
Source: DNS Clients Events
Event ID: 8018
User: NETWORK SERVICE
This issue is only affecting Windows Server 2012 R2 clients and testing with Windows Server 2008 R2 clients works no issues. So is this a mis-configuration or a bug with Windows 2012 R2? I have checked all DNS settings on client / server which all look good
to me so reaching out now to see if anyone has any ideas?
Environment:
- Windows Server 2012 R2 Domain Controllers (Forest/Domain Levels 2012 R2)
- Windows Server 2012 R2 Client machines (Physical and Virtual)
- Windows Server 2008 R2 Client machines (Physical and Virtual)

The zone is configured as "Secure Only"
The PDC is the SOA for the zone
I dont have a packet capture from the DC, only the client.
The query you asked me to run is too long to paste in here, however this is the DNS zone it cannot update:

I have looked at various threads in the forums here but I'm still stymied why the connection seems to be ok, yet sql developer has problems with it. If I create an ssh tunnel so sql developer only has to connect to localhost it works:

Hi Ali,
This may be of varoius reasons..
Is the database that you are connecting on the same PC?
You have specified Hostname: localhost.
If not please replace it with the IP of that server.
Else please check whether the database listener is started or not. if not please start the listener.
Check the SID by tnsping command.
Hope this will help you..
Thanks

SQL Developer: Failure -Test failed: IO Error: Network Adapter No Conn

SQL Developer: Failure -Test failed: IO Error: The Network Adapter could not establish the connection
Hi,
and sorry this is a really common questions and yes I did do a search, but I don't understand it.
First let me just tell you that Oracle 11g is installed on my second laptop on the same Network.
Secondly I can connect to the Database using Oracle SQL Developer on the laptop Oracle 11g is installed on.
The problem is I want to connect to the database on my main Laptop.
I put in the correct details Hostname 192.168.0.8 ( this is the laptop oracle is installed and running on)
Port 1521
SID dbarudu
****** YES I HAVE PORT FORWARDED
****** YES I HAVE ALLOWED 1521 on the FIREWALL
****** YES I HAVE EVEN SWITCHED OFF THE FIREWALL
Now one more thing you should know ... I don't know nothing about Oracle Servers ok.... so I have just installed Oracle 11g Enterprise and thought done it should be working now.
I just need to use oracle db for a project.
So keep in mind I am a total noob and terms like TNSPING etc mean absolutely nothing to me.
So please help, but help with step by step guide on how to get Oracle to let me have access from another computer.

If the Listener is working, then you should not get the error SQL-Developer error you are reporting.
The listener typically runs using the hostname and port 1521. This means it opens tcp port 1521 on all IP addresses of that platform.
The database server by default will register itself with the local listener. Thus the listener will know the database SID, the database services, whether there are dispatchers to support shared server connections and so on.
The client side needs simply to specify 3 pieces of data to connect:
- the IP of the database server
- the tcp port of the listener
- a database identifier (such as Oracle SID or service name) to connect to
It is really that simple.
If this does not work, the problem falls into 2 broad categories:
a) incorrect installation and configuration of the Oracle software (the out-of-the-box install works unless messed up)
b) some kind of networking issue
To troubleshoot any problem means reducing the complexity of the problem, eliminating multiple moving parts and focusing on specific ones, in order to isolate the problem.
For your problem, this will go something as follows:
- does the listener run? (check if the service is running and whether tcp connections are accepted on the listener port - telnet can be used for the latter)
- does the database successfully registers itself with the listener? (check the services command of the listener and relevant db initialisation parameters)
- does a local TNS (tcp network) connection work on that server? (use SQL*Plus and test on that platform client-server connectivity via tcp to the listener)
- does the client platform have connectivity with the server platform? (use ICMP and telnet to test)
- repeat the TNS test on the client platform using the same working TNS tested on the server platform
Do not use JDBC to test the connection - keep it simple and use sqlplus and the standard Oracle Call Interface (OCI). A full client version of the OCI plus sqlplus can be downloaded under the Oracle InstantClient downloads.
Finally - if you expect to simply install and use Oracle, then use the correct version. Oracle Express Edition aka Oracle XE. Installs and works out-of-the-box. The only manual config change to make is (as far as I recall) to run the listener on all IP addresses of that platform. And this required editing the listener.ora file, changing the HOST parameter and restarting the listener.
Also keep in mind that you have not presented an Oracle error code and Oracle error message. But a client application error message. And that message is pretty much meaningless - it does not point to a specific Oracle networking or Oracle server problem. To diagnose that, we expect a TNS or ORA error number.

That means the Oracle URL you supplied to the pool is incorrect forconnecting to the
DBMS you want. If the same pool definition works sometimes and sometimesnot,
then it's an oracle problem with rapid connection requests. Make the poolmake all it's

"Failed to install network adapter - check WINBOM"

Hello,
two weeks ago my network adapter and my soundcard ran away. I brought the laptop to an IBM premium partner, where the mainboard was changed with a notice all would be ok, but with a hint of the service technican that I should try to recover; the problem is still not solved. Yesterday I recovered from a very old version, when the network adapter and sound card worked properly. Since then my sound card works, but only with cracks. That is of course not acceptable. The network card does not work anyway.
When I boot my laptop with the ACCESS IBM button I get an error message from FACTORY.EXE "Failed to install network adapter -- check WINBOM"
I checked them, but there is no factory.exe on my hdd, as well as there is no winbom.ini on my hdd. I only found the and empty entry winbom in the registry.
In the system manager there is no network adapter listed (instead of the wireless ones). No way to install one.
I do not know what to do now. May someone think there is a solution available for my thinkpad or should I sent it to IBM/Lenovo?
The machine is a T43p 2668 PEG.
Cheers,
Herwig
Solved!
Go to Solution.

Welcome to the forum!
I'm surprised that the Business Partner hasn't offered to re-install the OS for you, but then again it may be a local practice that I wouldn't be familiar with.
Try borrowing/downloading a copy of a "live" Linux CD (Mint works out of the box on any T43/p with ATi) and see whether the issues persist there.
If they do, hardware is defective and you'll need to send it back in for another repair.
If they don't, re-installing XP from scratch, after saving the important stuff on media, is the way to go IMHO.
Good luck and let us know.

Trying to set-up the network adapter in Solaris 11 under Hyper-V fails

I was using Virtual Box to run Solaris 11 for testing purposes, however VB was disappointing as my VM hanged too often so now I am evaluating Hyper-V under Windows 8 Pro. If I can get the network to work I will use Hyper-V even if it lacks seamless mouse
and keyboard integration. So, I installed Solaris 11 in Hyper-V but I cannot get the network to work. What I have done:
- I have created a Virtual Switch of type External with Virtual Switch Manager
- I have created a Legacy Network Adapter for my virtual solaris machine
- in Windows 8 I have created a Bridge for my WiFI NIC and the Virtual Switch
I can access the internet from my host machine (windows 8)but I cannot do it from the guest (solaris)
If I type "ipadm" in my solaris's terminal I can see that the NIC is listed but it has no IP address. So how can I assign an IP address to the Legacy Network Adapter?
Thanks

Hi Brian,
Thanks for the reply. I have managed to get networking working by creating a legacy card attached to a virtual switch, but I have not used the bridging anymore, instead I simply shared in the host OS the wifi connection to the virtual switch. This way it works.
Now I have another problem with the Solaris guest OS not seeing the SCSI controller, but I'll open a new thread for this after some more testing.
Thank You

Thunderbolt Network Adapter not working after yosemite upgrade

After I upgraded to Yosemite, my MBP Retina 13" doesn't see the link on thunderbolt network adapter. The wireless is totally unreliable and freeze every few min for 1-2 min which is long enough to disconnect any sessions. Turn off and on of wireless works and recovers but it's royal pain. Any suggestions?
I scheduled call with Apple 3 times today. They call me back at the scheduled time and immediately tell me that I missed their call even though I pickup on 1st ring. Been waiting in their support queue for more than 30 min now and no one is on line yet.

the link provide above leads to http://plugable.com/2014/10/31/os-x-10-10-yosemite-ethernet-adapter-problems-we- can-help
...but these seem to be all 3rd party USB ethernet adapters and nothing to do with the Thunderbolt adapter of the thread - or am I missing something?
I have the same blooming problem, it seems to be totally hit and miss whether the adapter works or not.
I thought is was a faulty adapter, so even bought a second one for my MacBook Pro, so a bit more profit for the most profitable company in the world for a non working device. My ethernet cable works fine to an old apple USB adapter but is 90% useless with Thunderbolt.
Renewing the DHCP lease occasionally works, but totally unreliable, at the moment it fails.
Still looking for a reliable solution.
Come on Apple, please sort this out, you have a connector policy of turning everything you can into adapters and dongles rather than building them in, so you end up with a slim laptop and a bag of adapters to carry around, and then when they don't even work - doubly annoying.

Broadcom 802.11n Network Adapter not working on Windows 7 64bit

As the title suggests, my laptop (Alienware m17x) is installed with the Broadcom 802.11n Network Adapter and Windows 7 64bit Home Premium. I have had several other driver incompatibility issues with Windows 7, but those I have slowly been able to resolve. This however just cropped up after two months of successful use. Yesterday it started failing to connect to the internet, telling me that no wireless connections are available. I live in a dorm, and everyone else on my floor has successful wireless, including my Ipod Touch, PS3 and XBox 360. I called Alienware/Dell Support and we spent hours trying to fix the problem and all look well until I rebooted my laptop this morning and the same issue reappeared. When I reboot my laptop, all I get is a notification that no networks appear in range. If I uninstall the broadcom chip and let windows install it after a boot up it works until the machine is rebooted a second time. I have tried over a dozen windows 7 drivers for the chip, and about half a dozen vista drivers and they all have the same results, works on the first boot, fails every time after that

Just registered to say, on an Alienware M17x system as well running Windows 7 Ultimate, here is a link to a solution that worked exactly for me:
http://forum.notebookreview.com/alienware/436486-guide-properly-solve-wireless-connection-problems-m17x.html
All I did was section I.a. If the link is down, I copied the only section that I needed to follow out of this guide, in order to get my wireless to work repeatedly without having to uninstall the wireless driver every single reboot. Now it works perfectly,
already connected to a wireless network on startup.
I.a. Disable Device sleep on disconnect
Some newer Nvidia Ethernet drivers have a feature called Device sleep on disconnect. This is the culprit. Normally, it should only put the Ethernet adapter to sleep when the cable is disconnected, but it's buggy and thus kills the wireless connection as
well.
Follow these steps to disable this feature on your Nvidia Ethernet Adapter:
1. Open the Windows Device Manager by hitting Win+Pause, then click on Device Manager on the left side.
2. Double-click on Network adapters.
3. Double-click on NVIDIA nForce Networking Controller (yes, that's the wired Ethernet adapter indeed).
4. Click on the Advanced tab.
5. Select Device sleep on disconnect.
6. Set the Value to Disabled.
7. Click OK and wireless should work again (might require a reboot afterwards, but probably not).

If you're sure that you have a Broadcom BCM57xx
device installed in the machine, then you should have a look at
"prtconf -pv" output, locate the Ethernet device, and check the
"vendor-id" / "device-id" property for the NIC.
If the Broadcom device is compatible with Sun's "bge" driver, you
can try to install an addition driver binding entry for your device,
using the update_drv(1M) command
update_drv -a -i '"pciVVVV,DDDD"' bge(where VVVV and DDDD is the pci vendor / device id found in
prtconf -pv output).

Windows 7 x64 Network Adapter Stops working on high load

My Network has been failing and it has been happening for about a month or so on Windows 7 x64. I dont think that the system configuration is the problem as it is happening on 2 seperate machines. One being a relatively beefed up "white" box, 4 gig OCZ ram, EVGA nForce 790I SLI Mobo, Q9600 Quad core processor, dual raid 1 - 150 Gig Raptors, 2 8800GTX SLI cards, Pure Power 800W PS. The second machine is an IBM Netbook S10. I use the Netbook as a media center connected to a Pioneer Elite 1050HD. One thing is I have a PS3 and have several 1TB Esata drives connected to an IOGear 3132 Esata 3.0Gb pciX card to my desktop.
My typical usages:
1. FTP from a private server
2. Streaming music via Winamp
3. Streaming video 720, 1080 from pc to PS3 via the PS3 Media Server
4. DLing demos or movies on the PS3
5. Network streaming a movie from the Esata drives to the bedroom or kids rooms
6. Streaming video from abc.com or southparkstudios.com from the Cox cable modem
7. RDC over VPN to work machines
Now I have noticed that when I am streaming HEAVILY, from any 2 of the above mentioned, my network connections will simply stop working with a yellow exclamation mark on the task bar network icon after a few moments, nothing in the event logs, no logs or ANYTHING at all. It will simply stop working no notifications or anything poof, gone. I have EVERY single patch, driver anything I can think of installed. Nothing works, the timing is completely random. FYI I have a NETGEAR ProSafe VPN Firewall FVX538 with a cable modem connection on WAN 1 and a cellular connection on WAN2, these have no impact I feel on the connections because the PC may go down or the Netbook will go down depending on which one has the most load. So this simply tells me that it it not a firewall router problem as I have tried using a cisco unmanaged 24 port 1GB switch and I get the same problems. From analyzing the systems and layout I am led to believe that it is either a network adapter driver OR a Windows 7 problem (collisions, unhandled exception?), this NEVER happened with XP or Vista. I have tried everything but a new network adapter, I have tried the secondary adapter card on the mobo, I have tried bridging the two, I have tried daisy chaining the switch and putting each machine on its own dedicated switch linked to each other with no change. When the network goes down it is only that box effected, all other machines still connect to each other fine, only the one with load shuts down and the only ones that shut down are Windows 7. These machines are all wired with commercial cat5e patch cables, they have all been swapped for new ones lately. All networking and PC equipment are on UPS so I doubt voltage variations. Windows Firewall is disabled I only use the hardware firewall, I do not use any antivirus.
I am completely out of options, can anyone recommend a new route?
In addition when I go to the command prompt and attempt to do an ipconfig /release. I get an error saying that the adapter is not in a usable state. Very irritating, this forces me to reboot, or right click disable/enable on the network adapter. The right click route takes almost a minute to complete.
Tried update driver in nvidia control panel, no luck. I have also turned off the networking power saver option in the adapter settings.

Hi,
Considering this issue occurs on 2 different machines, I also think this issue may be more hardware related. You may also try the following:
1.    If the computers are connecting to a router, please ensure the router’s firmware is up-to-date.
2.    Please run the following command in an elevated command prompt in Windows 7:
netsh interface tcp set global rss=disabled
netsh interface tcp set global autotuninglevel=disabled
netsh int ip set global taskoffload=disabled
3.    Disable SNP in Windows 7 by setting Registry as following:
Note: Please perform a full-system backup first.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
EnableTCPChimney=dword:00000000
EnableTCPA=dword:00000000
EnableRSS=dword:00000000
If the keys do not exist, please create them and assign the value.
An update to turn off default SNP features is available for Windows Server 2003-based and Small Business Server 2003-based computers
4.    If the issue persists, please add another network adapter to this computer and see how it works.
Hope this helps. Thanks.

Hi, I'm experiencing a simular problem here.
My PC was using Asus P5Q-E motherboard but exchanged it for Asus P5Q TURBO Pro because it loses 'connectivity ' after an interval between a few hrs to 26hrs. During this state, I can't browse or my Outlook to check emails. The only thing that can send/receive data is Vuze. Plus, the strange thing is that the network icon says there's nothing wrong at all (when it obviously there is). Even the currency desktop gadgets says the time elapsed since it 'lost connectivity '.
I initially thought P5Q-E was faulty so now I'm using the TURBO Pro. However, the problem still persisted.
I am using Win 7 Ultimate x64 with all the updates and drivers. Connected via LAN cable to the router and the firmware is the latest. My ISP sent me a replacement router to confirm that their equipment is not faulty, which is true.
I have tried the above methods 1-3.
Although I'm not sure if I implemented Method 3 correctly since I don't usually go to the registry but here's what it looks like after creating it:
EnableRSS   REG_DWORD   0x00000001 (1)
EnableTCPA REG_DWORD   0x00000001 (1)
EnableTCPChimey REG_DWORD   0x00000001 (1)
There are 3 more PC's and 1 laptop in the house. 2 PCs use Win XP, 1 uses Win 7 Ultimate x64 and laptop uses Linux Ubuntu.
My PC has a second OS, Linux Ubuntu, I used it to time trial both motherboards (before and after switching) and found no problems at all even after 48hrs, so it confirms it's not a hardware issue.
The other PC's apart from mine are connected wirelessly. As far as I've been told, they don't experience the same issue I have.
I've been trying to tackle this problem for months now and I'm frustrated to reboot my PC every time it 'loses connection '.
I chatted with Asus about the issue when I still had the P5Q-E mobo, they said that they built a simular system to mine with the same mobo and said they couldn't reproduce the problem I'm having. THey even tested on other mobos with the same LAN chip and found nothing wrong. That's why I got the TURBO Pro that has a different LAN chip.
Anyone got anymore suggestions???
Thanks in advance.

Network adapter not working

Hi,
This has been quite a confusing few days with this network adapter. It's a Realtek 8139C based card, but for some reason Arch refuses to get it to work with either 8139cp or 8139too modules.
Both have been added to rc.conf modules list (independently and together) & I've tried blacklisting one then the other but eth0 still doesn't show up in ifconfig. Even with 8139cp blacklisted, at boot I still get a message about that module telling me to try 8139too instead. I also get a message saying: "PCI: Unable to reserve I/O region #1:100@de00" and that something fails with error -16.
So far, the only way I've managed to get the card working is during install and getting the setup program to probe for a driver and setup dhcp itself, which to my mind shows that the card is fine, as I managed to download the entire base package with it. If I could find out what the setup program does to get it working, it might help too.
Any ideas? Any help would be greatly appreciated.
P.S. Please forgive how vague this post is, I don't have the machine in front of me right this instant.

I did some research and found that the drivers for Linux are in the Realtek site (very hidden though ) at this URL

Hope this helps.

Io exception: The Network Adapter could not establish the connection

Hi All,
I run tomcat and connect to Oracle fine, both on the same machine.
I also run some batch processes daily and they often run without problems. The batch processes lots of selects and updates/inserts onto Oracle.
These tend to work fine, but sometimes when they run I get
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
So a batch process will be running doing lots of selects and updates then it just decides it had enough and throws this error each time it tries to connect. Meanwhile tomcat continues to run fine through the same TNS listener, but subsequent batch jobs fail to connect.I normally have to restart the TNS Listener.
I connect through the same class whether connecting through Tomcat or from the batch process with this:
public static Connection getConnection(String caller) throws SQLException{
try{
Connection con;
if (standalone){
try{Class.forName(driver);}catch(ClassNotFoundException e){}
con=DriverManager.getConnection(url,user,password);
return con;
}else{
if (ds==null)initialiseContext();
con=ds.getConnection();
return con;
}catch(SQLException e){
ds=null;
logger.debug("Problem in DBAccess.getConnection()...");
logger.debug(e.getMessage());
e.printStackTrace();
throw e;
I specifiy params such as MaxIdle with Tomcat using the xml config but not when its standalone - could this be affecting it?
Any idea?
Thanks.

Oracle should be able to handle lots of connections no problem, I agree, and it is through tomcat.
Yet the exception that you get says that it isn't. Oracle, for example, on a single box shouldn't be able to handle 100,000 simultaneous connections.
I would be very surprised if it couldn't handle 1,000. And if there was an issue at that point it would be a resource bound issue, like CPU (on the single box) rather than connections.
You suggested licensing issues?I believe at one time, not necessarily now, the Oracle server would be sold such that it limited the number of simultenous connections. This could have been a relatively low number. There are quite a few assumptions in that - the major one would be it is based on my faulty memory and second would be that it was years ago.
By the way you are not running this on a unix variant system without redoing the kernel limits to set up for a server system right?
