VM Guests coming up with No Network after rebooting.

Howdy,
We have a random problem in that when we reboot our VM guests, they sometimes come back with no network connectivity at all. We cannot ping them or remote into them. When I access them from the console, the Network icon shows the warning symbol
and says: "No Internet Access".
If I check an ipconfig, it shows a 169 address even though we set static IPs on all our servers.
All I have to do to fix it is Disable and Enable the network adapter from within Windows and then everything goes back to normal.
VM Hosts are running 2012 and Guests are mostly running 2012 R2 if that matters.
Anyone have any idea what would cause this to happen?
Thanks!

Hi Kelemvor33,
Did you configure this VM a VLAN option use any advanced NIC option on Hyper-V host or VM, please install the latest update with your Hyper-V host and this vm then monitor this
issue again, from your current description it seems like the known issue and you can install the following KB to solve it.
A restarted virtual machine loses connectivity after you set the "Private VLAN (PVLAN) networks" option in a Windows Server 2012 R2 environment

IPad2 got a terrible trouble with 3G network after updateing to IOS5.1.1

Hello guys, I got a terrible trouble with 3G network after updateing to IOS 5.1.1. Now when I turn on my cellular data, the iPad 2 can say the carrier and 3G on the left top. But when I tap the Safari, it turns to be:"PDP authentication failure". I did the update to 5.1.1 last night, before that every thing is fine, and now I can't use my 3G at all.
Could anyone please tell me what's happing and what should I do???
Thank you so much!

Problem with 3G network after ios 6.1 upgrade on iphone 3Gs.

I have a iphone 3Gs and not a 5 or 4 and since my ios 6.1 upgrade it's a nightmare for me. I meet a lot of reliability issue with the 3G network. Before the 6.1 upgrade it worked fine. My carrier provider is SFR. It seems to be a "bug" only with 3G. Maybe it's the same as 4Gs but not corrected for 3Gs.
By example I'm using my iphone to join a Free Number to join a confcall system and everytime after sometimes 3 minutes or 15 minutes I'm automatically disconnected - nobody is hearing me and I have to switch off and to reconnect. Others collegue working with me having a iphone 3Gs meet the same issue as me with 3G network.
Do you plan to release the 6.1.1 version for iphone 3Gs ? if yes ? when ?

After testing workaround to disable WIFI when I'm using 3G network. It worked for 1 confcall during 1 hour !! but for the second confcall the duration was only 6 minutes and the network was cut !!! the workaround doesn't work !.
I'm surprise because I don't find similar issue on Internet with "Reliability of 3G on iphone 3Gs after ios 6.1 upgrade!!".
This morning during a call this message appears "Could not activate cellular data network".
Are you in the same case as me ? Do you have a workarounf for me ?

Z68A-GD65 (G3) loses network after reboot

Hey there,
I had to re-install my windows 7 this week and I cant believe I didnt write down the solution to a major problem I remember having before with my network on this board....
With all the latest drivers from the MSI site installed, after every fresh start I lose my network connection, the icon shows a yellow exclamation mark and I have to disable and enable the network connection to make it work again.
Does anyone remember what the hell this problem is?? I can't believe they didn't fix this in the drivers, because its a major problem that has already cost me many hours of troubleshooting last time....I fixed it on my old installation because I have been working for 2 years now , but I dont remember how I fixed it ...
Also, I can't believe that in the official driver section on the MSI site for my board, there are dead links , the link to the W7 64 bits drivers for "Intel Rapid Start Technology Driver for 6x Series " do not work.
Don't I need that?? If not, please remove the link, if I do, please fix it, but its crazy to have this kind of errors on an official site I think...
Marcel

Unbelievable that nobody at MSI seems to know how to solve this , I'm sure I'm not the only one, I've seen people in forums buy an extra network card to resolve this actually....
But for others that encounter this problem too (Or for my own reference when I forget again next year) I think I solved it myself (again!):
It's the Apple Bonjour service that is installed by Apple products or with for example Adobe products that is causing this.
The solution for me was to go into the services , look for the Bonjour service which is probably the one on top of the list with the ridiculous name that starts with ##id string , looking like a virus. I swear I have seen it on more than one occasion and feared I had a hackertool installed!
You then set the startup type from 'automatic' to 'automatic delayed', no more problems.....
Apple, be different....lets up peoples windows computers

Problem with swap files after reboot.

Hello
I have installed Solaris 10 10/09 s10x_u8wos_08a on a Sun Fire X4140.
The file system is UFS.
I wish to add more swap space
I have created these two files under /export/home:
-rw------T 1 root root 5368709120 Jun 16 10:12 newswap
-rw------T 1 root root 2147483648 Jun 16 10:38 newswap2
When I enter swap -a /export/home/newswap, the command succeeds and I can see the additional swapspace with swap -l.
I have the following configuration in /etc/vfstab
# cat /etc/vfstab
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
fd - /dev/fd fd - no -
/proc - /proc proc - no -
/dev/dsk/c1t5d0s1 - - swap - no -
/dev/dsk/c1t5d0s0 /dev/rdsk/c1t5d0s0 / ufs 1 no -
/dev/dsk/c1t5d0s7 /dev/rdsk/c1t5d0s7 /export/home ufs 2 yes -
/export/home/newswap - - swap - no -
/export/home/newswap2 - - swap - no -
/devices - /devices devfs - no -
sharefs - /etc/dfs/sharetab sharefs - no -
ctfs - /system/contract ctfs - no -
objfs - /system/object objfs - no -
swap - /tmp tmpfs - yes -
Although it is supposed to work, after reboot, the only mounted swap file is /dev/dsk/c1t5d0s1.
The two file under /export/home aren't mounted as swap. Why?
Can anybody give me some help on this issue?
Thanks

Actually you don't have to create a dedicated slice/filesystem for swap.
You can create files and then use them as swap.
Here is the link from the documentation of Solaris
http://docs.sun.com/app/docs/doc/817-5093/fsswap-59089?a=view
My issue is that although I have configured /etc/vfstab according to the documentation, the swap files aren't automatically mounted on boot. I can only mount them as swap manually with swap -a.
Can anybody help?

Problems with SD Card After Reboot

Hi, I formatted my SD Card through my Xperia Z3 with Lollipop.I erased all data from Spotify, included the folder spotify.music.Installed the Spotify again with the SD Card connected and all worked fine.I did download from all my albuns, and verified on File Commander, and all data were in SD Card. The problem-->>>After reboot the phone the SD Card isn´t recognized.I did all procedure again, and all return to work, but every time that I reboot the phone, I have to do do all these again. I tested format the SD Card and reboot my phone many times, and it´s all right.It´s necessary only a logon Spotify and the next reboot the SD Card don´t read more. Please, can you help? Thanks a lot!!!

Hi Spotify Family, My problem was resolved.I changed my SD. After was 128GB Ultra SandiskNow 32GB normal Sandisk -> http://www.bslive.com.br/acessorios-informatica/149-cart%C3%A3o-de-mem%C3%B3ria-32gb.html Remember that you have to erase all cache and uninstall the Spotify again before input the new SD Card. Good Luck for All

I got problem with my network after I switch the SIM card.

I've go back to china in my summer holiday and of cause switched to a chinese SIM card. But im not able to use any software to get on the internet with it although it does show 3g on the top left coner. everthing else are working fine, i can dail, pick up phone calls, send or recieve messages, and one of online chating software which is a bit like MSN is still functioning. I've asked local shops and customer service, and tried everything they suggest like reset network, reset the whole phone and i even recovered it to its initial status, but the network still the same. The SIM card works fine and it is able to connect the internet on my friends cell phone, and i used it last summer holidy without any problem at all.
I'm guessing there might be some setup problem after i upgraded the system, I really hope someone can help me with this problem.

Hi,
What version of the OS did you upgrade from ?
Anything before OS X 10.8.2 may have an issue if the Logic/Mother board has been replaced and the Serial Number not "flashed" back to it.
In the Apple Icon menu use the About this Mac item.
In the new panel click twice on the line that tells you the current OS level
It will change to the Build number (and alternative count to the OS versions) and then the Serial Number.
If it is missing you need to get it replaced.
(It is supposed to be done on Repair or Refurbishment).
An Apple Store or Apple Authorised Service Provider as the best choices.
There are apps you can download (They are Mac Model specific) but needs careful typing as it is a once only trip.

Problems with wifi network after waking from sleep

I have recently started using a new wifi network and have had some problems connecting to it. When i first tried to connect it gave a message that said "An error occured while trying to join". After some trial and error, I found that I could connect by going to network preferences, clicking "Assist me...", then "Diagnositcs...", clicking the AirPort dot then continue, then clicking on the network name and continue, then it prompts for a password, but there isnt one so i just pushed continue and all of a sudden it connected. I figured it was functional now, but after waking it from sleep mode, the error message popped back up. The only way I know to connect is through that annoying diagnostics path... What is the Problem, is it the computer or the router or the settings on the admin computer? (by the way, I don't know what kind of router it is, but its definantly not an apple airport)

Sorry to drag this back up, but I may have found the source of the problem, I just need the solution. When I first created settings for the network, it automatically "detected" that the security was WPA2 Enterprise, and knowing there was no password, I just pushed join and it saved it that way. When I go through diagnositics as described before, it lists WEP as the encryption. I had a friend with almost the same problem, but in tiger. They were able to fix it by changing the encryption on the login screen that comes up when you click on the network name from the menu bar. But that screen no longer exists in Leopard, it only goes by previous settings. How do I change the encryption in settings, I'm sure it will fix the problem...

I keep trying to activate my trial version with the code but it keeps coming up with trial version after i key in the code?

can anyone help it is version 8?

I hate to tell you this... they hacked your phone. ONLY the carrier it's locked to can authorize unlocking it. It can't be legitimately unlocked at a 'shop'.
First, try restoring it in DFU mode and see if it will at least activate with the original carrier it was locked to. If it will, contact that carrier and find out what their unlocking policy is and what you need to do to qualify.
If it does not work after a DFU mode restore, recycle it responsibly and buy a phone that works. it's hosed.

2008 R2 Unidentified Network after Reboot

Hi,
We have two new servers running Server 2008 R2 and we first noticed a problem connecting to them with RDP after a reboot. The problem was the firewall would not permit access because the NLA service could not identify that it was on the local domain
network. After updating the firmware on the system (HP DL380) and the NIC (Broadcom NC series) and installing the latest NIC driver, we are still experiencing the problem of being able to connect after a reboot. While I can disable the firewall,
that is not preferred. It also seems to have occurred after installing Hyper-V. If I remove Hyper-V the problem seems to go away. Using a single NIC, no teaming, etc. Other unused NICs are disabled. Any help would be greatly appreciated.
Thanks.

Hi Darage,
Thanks for posting here.
The NLA service is used to determine the network profile. When a machine boots up or comes out of hibernation the NLA service that runs using the Network Service account will send an LDAP bind request to a domain controller in its site via port 389. The Network
Service Account uses the client’s domain machine account when performing this bind. If the client can successfully bind to a DC in its domain, the network connection category will be set to “Domain”. If an LDAP bind is unsuccessful the network category is
always public unless specified as private by the user.
Network Location Awareness Service Provider (NLA)
http://msdn.microsoft.com/en-us/library/ms739931(VS.85).aspx
According to the your description, the domain profile is not detected properly. In this case, let’s check the following:
1.       Verify the Network Location Awareness service is Started and the Startup type is “Automatic”. Restart the NLA service.
2.       Disable and re-enable the NIC which connects to the domain network. Meanwhile, please disable the all unused NICs.
3.       The Network Location Awareness (NLA) service expects to be able to enumerate the domain’s forest name to choose the right network profile for the connection. The service does this by calling DsGetDcName on the forest
root name and issuing an LDAP query on UDP port 389 to a root Domain Controller. The service expects to be able to connect to the PDC in the forest domain. If something hinders the DNS name resolution or the connection attempt to the DC, NLA is not able to
set the appropriate network profile on the connection. Please ensure that the problematic clients can contact root DC properly.
For more information please refer to the blog post below:

RDP issues with SBS 2011 after reboot

I'm having trouble RDP'ing back into our SBS2011 server after doing a reboot on it, trying to re establish the RDP connection fails. I can't get back in until I call and have someone onsite physically log the server back on, then I can RDP back in just fine. Ideas?
This topic first appeared in the Spiceworks Community

Hi:
Failed updates were once a no charge call to MS for assistance, so I would try that and see how they react. Also, most failed updates will install on the second pass or you can visit the KB and download and install manually.
Just for others reading this... it is an excellent idea to reboot the sever before installing updates just to check that there are no issues. We have found that updates get blamed for things that have crept into the system before the updates were applied.
For the case at hand... I would not expect to see failed updates result in the behavior you are experiencing. May I suggest that you find the time to start the server with a clean boot (use msconfig to stop all startup items and non MS services
and restart). Then try the updates again, one at a time. If that does not work, try safe mode that will even turn off such as network drivers and even change the exchange services to disabled for this test.
If there were hardware driver updates installed, remove them and drop back to those you were using before. Make doubly sure the drives are not full, and that the RAM is not totally used.
Examine the event logs for clues, and run the SBS BPA - fix anything it finds.
And maybe let us know, in this last case, if dot net 4.51 was installed and what updates failed to install.

My external Firewire drive keeps coming up as read only after reboot.

Hello everyone,
I have a perplexing problem that just cropped up yesterday. I have an iMac (9,1) running Mac OS X 10.6.7. I've had the machine about a month now. I have an external 500GB Firewire 800 drive that holds all my iTunes music files. This was previously an internal drive in my G4MDD that I installed in an external exclosure I got from OWC. It's an EZ QUEST enclosure with an Oxford chipset. The drive is formatted Journaled HFS+, and I had reformatted it and copied all my files back over using Carbon Copy Cloner when I installed it in the enclosure. The drive is set in the Get Info window to "ignore ownership on this volume", and I have read/write permissions on the drive and the enclosing folders, including the iTunes folder. I can read the files, just not write to any directory on the drive.
Everything had been working as expected until yesterday when I started up the Mac and went to download a Podcast. The Mac informed me that it couldn't download the file because I didn't have write permissions. I checked the drive in the Get Info window, and everything was set correctly, but I noticed that I couldn't change the ownership options, as they were grayed out.
I fixed the problem by running DiskWarrior 4.2 on it, and rebuilt the directory. After that the drive was fine; until I started up today and was faced with the same situation. I was able to fix it again in the same manner, but would like to get to the bottom of the problem. A few other bits, the drive was recently defragmented with Drive Genius 3.1, and both that and DW and Disk Utility say the volume is OK.
I've been using Macs professionally and at home since '93 and this is my 5th Mac since that time. So I know my way around them, and I'm stumped!
Any ideas?

Oh, as part of this, not sure when the change was made, OSX used to keep the mounted volume name in /Volumes, even if the volume was ejected. Would cause an occasional problem - but very rare. I notice now that ML seems to create/delete these mountpoints automagically - and that's part of the problem. They get incorrect permissions when the volume mounts, and I (user I'm logged in as), can't write to the volume without some background shenanigans.
My process is this:
Unmount problem volume
Drop to terminal, and "sudo mkdir /Volumes/<mounted_volume_name>"
Remount volume via Disk Utility (you now get a "<mounted_volume_name> 1" - with CORRECT permissions)
Unmount the volume again
Remove the created directory (i.e. undo step 2)
Remount the volume - 99.9% of the time that seems to fix it.
Reboot to be sure - and it stays for a while - then at some point becomes a problem again.
Not sure if it's something in ML that's an issue - or something in iTunes or iPhoto (but can't see how they would affect the permissions when the system reboots and you login)

Who do "open with" defaults change after rebooting??

All,
I tried to launch this question in different words before but somehow never got a reply.
I know in "get info" you can supposedly change the default with "open with ---> change all".
Supposedly.............it works, until you reboot.
I want NOT to use preview to look at pictures because I do not like the fact that you can`t work with the arrow "next / last" or with the keyboard arrows.
Now people already explained to me how to select all pics in preview etc, but that´s too complicated for just looking at a few picture quickly. Also it´s not my question.............
My question is: how do I change my default picture viewer for good??
I tried it the windows way............right click on a picture, open with and tick the box "always open with" at the bottom but that don´t work either, I´m afraid.
I spent 2 hours trying............I even deleted Preview from "programs" but this defaults to a picture adjustment program..........still not what I want.
I like Xee, went into preferences of "Xee", ticked the files that it has to open, it works fine............until I reboot. Am I the only one in the world that struglles with this??
Please Apple-gurus...........help me!!
Surely Leopard hasn´t got this error?? Why bother with an "open always" button if it gets reset as soon as I happen to switch off my Macbook Pro??????
Does Snow Leopard change this perhaps??
Cheers,
Not a Clue.

Well, not exactly. You said you tried using Open With, but that could have been from the contextual menu as opposed to using Get Info. I interpreted the former from your post.
If they are not permanently changed it could be for a variety of reasons. One is the filetypes/extensions are not similar. For example changing the default for a .doc file is not the same as changing the default for a .docx file. Also changing the default for a document without an extension isn't likely to work. To work properly the document file must have the normal extensions assigned by the default application that opens that file.
Another possibility is a problem with the LaunchServices database. You can try resetting it as follows:
Rebuild LaunchServices Database
For Tiger users
Open the Terminal application in your Utilities folder. At the prompt paste in the following command in its entirety:
/System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServic es.framework/Support/lsregister -kill -r -domain local -domain system -domain user
Press RETURN.
For Leopard users
Open the Terminal application in your Utilities folder. At the prompt paste in the following command in its entirety:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchSe rvices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user
Press RETURN.
And, if you haven't done so already I would suggest the precautionary:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
