Hyper-V 2012 R2 does not disable the protocols on the physical network adapter

Hello,
I have a problem with the creation of an external network in Hyper-V (2012 r2), when I create the external network does not want to share with the host, therefore I take the check to share it. Hyper-V on the network adapter "real" does not disable
all protocols, but active all inclusive TCP4 and 6.
How so?
I have 2 other servers with the same configuration and run regularly.
Thanks in advance

Hi Fabio,
"when I create the external network does not want to share with the host, therefore I take the check to share it. "
Based on my understanding ,after creating a external Vswitch the physical NIC will only have protocol "hyper-v external virtual switch " whatever we check "allow management operation...." or not .
Do you mean after you create the external Vswitch , the physical adapter still have another protocol ?
If yes , my suggestion is to remove the physical NIC from "device manager " , then restart server and reload the driver then create the external Vswitch again .

Guest VM failover cluster on Hyper-V 2012 Cluster does not work across hosts

Hi all,
We are evaluating Hyper-V on Windows Server 2012, and I have bumped in to this problem:
I have a Exchange 2010SP2 DAG installed on 2 vms in our Hyper-V cluster (a DAG forms a failover cluster, but does not use any shared storage). As long as my vms are on the same host, all is good. However, if I live migrate or shutdown-->move-->start one
of the guest nodes on another pysical host, it loses connectivity with the cluster. "regular" network is fine across hosts, and I can ping/browse one guest node from the other. I have tried looking for guidance for Exchange on Hyper-V clusters but have not
been able to find anything.
According to the Exchange documentation this configuration is supported, so I guess I'm asking for any tips and pointers on where to troubleshoot this.
regards,
Trond

Hi All,
so some updates...
We have a ticket logged with Microsoft, more of a check box exercise to reassure the business we're doing the needful. Anyway, they had us....
Apply hotfix http://support.microsoft.com/kb/2789968?wa=wsignin1.0 to both guest DAG nodes, which seems pretty random, but they wanted to update the TCP/IP stack...
There was no change in error, move guest to another Hyper-V node, and the failover cluster, well, fails with the following event ids I the node that fails...
1564 -File share witness resource 'xxxx)' failed to arbitrate for the file share 'xxx'. Please ensure that file share '\xxx' exists and is accessible by the cluster..
1069 - Cluster resource 'File Share Witness (xxxxx)' in clustered service or application 'Cluster Group' failed
1573 - Node xxxx failed to form a cluster. This was because the witness was not accessible. Please ensure that the witness resource is online and available
The other node stays up, and the Exchange DB's mounted on that node stay up, the ones mounted on the way that fails failover to the remaining node...
So we then
Removed 3 x Nic's in one of the 4 x NIC teams, so, leaving a single NIC in the team (no change)
Removed one NIC from the LACP group on each Hyper-V host
Created new Virtual Switch using this simple trunk port NIC on each Hyper-V host
Moved the DAG nodes to this vSwitch
Failover cluster works as expected, guest VM's running on separate Hyper-V hosts, when on this vswitch with single NIC
So Microsoft were keen to close the call, as there scope was, I kid you not, to "consider this issue
resolved once we are able to find the cause of the above mentioned issue", which we have now done, as in, teaming is the cause... argh.
But after talking, they are now escalating internally.
The other thing we are doing, is building Server 2010 Guests, and installing Exchange 2010 SP3, to get a Exchange 2010 DAG running on Server 2010 and see if this has the same issue, as people indicate that this is perhaps not got the same problem.
Cheers
Ben

External display on late 2012 macmini does not go to sleep.

External display on late 2012 macmini does not go to sleep, instead the content freezes. After Pram reset it does go to sleep, till it undergoes next system sleep cycle (hibernatemode 25). I need to suspend it to disk because it is an offgrid setup and the power needs to be cut between Sessions. Display is connected to the hdmi port. Runing OS 10.8.4. Reinstalling did not help, neither. I have struggled with this for half a year now, it accured about 2 month after first use of the machine.
Thank you for possible help!

Next on my list would be an installation from scracht - wich i would obviously love to avoid
The bewildering thing is that through a pram reset i can get the display to sleep once again...
Maybe a hardware prob?
Might want to check using the thunderbolt port instead, as soon as i can afford the adaptor.
Anyway i will go to offline world for some time now, on a crazy bicycle tour trough remote eastern europe.
I would love to hear from you on an occasion of a peek to cyberworld during my trip!
So long

Because line-in has been removed.
It does allow for an Apple headset with mic., but I don't know if it would work with third-party ones.
You'll need to use a Griffin iMic or similar to use line-in via a USB port.
The same goes for the 15" retina, the newest MBA and the new iMac (whenever it finally arrives).

try disabling email scanning for incoming mail.
One of the last things that occurs is the mail server and Thunderbird sign off on "where we are up to" and Thunderbird stores this state information in the popstate.dat file in your profile (there is one in each POP mail account folder). If the anti virus, or you for that matter, end the conversation a few seconds early that hand off does not occur and the popstate is not stored.

You seem to have made a copy of the standard program. You'll have to make sure that you are handling this field correctly in your code.

Every time I launch Firefox it pops up an error stating "Firefox could not install this item because "install.rdf" (provided by the item) is not well-formed or does not exist. Please contact the author about this problem."

Firefox could not install this item because "install.rdf" (provided by the item) is not well-formed or does not exist. Please contact the author about this problem.
The statement above is in the pop up error box every time, when I launch Firefox. If I click ok in the box Firefox then opens. How do I fix this initializing/launch problem?

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). 
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. 
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions. 
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Firefox does not open when clicking on the icon, the firefox.exe process consumes 99 % of the CPU and my computer runs slowly.

I have been a happy user of Firefox for many years. Around last April first I opened Firefox and was offered an update to v 4.42.0.0 which I accepted. Installation seemingly went well. I forget now exactly what happened but the result has been that ever since April 1 I haven’t been able to open the Firefox browser when clicking on the Firefox icon. My computer now was running very slowly. I tried to uninstall Firefox, but a popup told me I couldn’t because Firefox was in use. This confused me because I couldn’t see it being used. Only now I have found that on Task Manager processes that “firefox.exe” was consuming 99 % of the CPU. After removing firefox.exe by clicking End Process my computer ran better. I uninstalled Firefox I had on my computer and installed Firefox 5.0. Unfortunately I have the same problems: Firefox does not open when clicking on the icon, the firefox.exe process consumes 99 % of the CPU and my computer runs slowly.

Born2die! Brilliant. I am a desktop clicker and never knew Firefox had a safe mode.
Thank You!
I was unable to start in safe mode initially. The second time I disabled all of the Add-Ons and she started up just fine. I enabled them one by one hoping to track down the culprit but the problem seems to have gone away.
BTW I am running ver. 3.6.8 (in response to cor-el's earlier post) and
Firefox is in the process of downloading 3.6.10 (which I am starting to think may have been what caused this whole problem to begin with)
Incidentally, whats up with all of the Java Console Add Ons?
I have:
Java Console 6.0.11, Java Console 6.0.13, Java Console 6.0.15
Java Console 6.0.17, Java Console 6.0.20, and Java Console 6.0.21
What are they? Do I need them? Can I uninstall them? Is this due to using Open Office?
Also, .NET Framework 0.0.0 Should I uninstall it?

I cannot open more than 1 Tab per window. The "+" does not work as well as the item "New Tab" from the File drop-down menu. What shall I do ?

I have just removed FireFox and reinstalled it again on my Mac Book PRO.
When I open FIreFox I canNOT open more than 1 TAB.
I click on the "+"on the top line of the window. It should open another TAB but id does NOT.
I click on the File item in the top menu bar. A drop-down menu pops up. I click on "New Tab" and nothing happens.
How can I get more than 1 Tab on the same window ?
This feature works with Safari !
Thank you so much.
Best regards

We have seen reports about a Community Toolbar extension causing this issue with not being able to open a new tab.
So if you have such a toolbar then start with disabling it.

Do you have that problem when running in the Firefox SafeMode? ''A troubleshooting mode.'' 
1.You can open the Firefox 4.0 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut. 
2. Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. 
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut to open it again.''

Macbook Pro 2011 DVI HDMI out does not work with TV when the power cable is connected

My Macbook Pro (Early 2011) DVI HDMI out does not work with TV when the power cable is connected. If get the blue screen and then can use the macbook but nothing is displayed on the TV. If i go into display I can see that there are two screens but nothing displayed on the TV. If i take the power cable out at this point the TV shows the second desktop as expected. If i then reconnect the cable, the screen flickers, as though it is being affected by the power cable, and the screen goes blank on the TV. Only if i remove the DVI cable do i get the blue screen again. If i remove the power cable and reconnect it will do it every single time, so i cannot see it being a TV issue or a minor glitch.
I have had this working previously but at the minute it seems to not be playing ball....any thoughts
Thanks
Dan

My ipod nano 3rd generation, when connected by usb, does not show up in itunes, does not show up on my computer, does not seem to charge by the wall charger. It just has a black screen. Any ideas for me?
I've run diagnostics. Can't find device. I've tried resetting. The toggle has been turned on and off.

Cable works fine on my other iPod. Reset by pressing menu and center button together for 6-10 seconds. Left it to charge for many hours. Started acting up while running. Suddenly the music stopped playing but my Nike + was still working for the rest of my run. Took it straight it home and plugged it in to the wall to recharge since the battery was fairly low. Looked like it recharged ok but then screen went blank and now does it not show up on iTunes, does not seem to recharge by the wall charger (apple wall charger plugged into a surge protector in India). I have turned the hold switch off and on many times.
Sounds like a repair issue, which is not easy to do in India :(
