Screen Sharing trying to connect to Apple Kerberos server?

I'm using a MacBook Pro running 10.10.1. When I connect to other Macs via Screen Sharing, it now takes a very long time to connect (a lot longer than when I was on 10.9).
The culprit seems to be this:
1/7/15 11:00:08.606 AM NetAuthSysAgent[10688]: NAHSelectionAcquireCredential The operation couldn’t be completed. (com.apple.NetworkAuthenticationHelper error -1765328228 - acquire_kerberos failed username@WELLKNOWN:COM.APPLE.LKDC: -1765328228 - unable to reach any KDC in realm WELLKNOWN:COM.APPLE.LKDC, tried 1 KDC)
So it's trying to look me up on Apple's Kerberos server, and timing out. Any way to stop Yosemite from doing this? Or is there another solution?

Make a rule in Little Snitch to forever deny outgoing connections for NetAuthSysAgent to port 88 (kerberos).
No more delays.

It is stated that mirroring requires recent hardware (2011 or later)

However you can still use 3rd party solutions like Airparrot which do it via software

Screen sharing stuck on 'Connect...' - but only on one client account. Please help!

I've got a bizarre problem that cropped up sponaneously, and which I can't for the life of me seem to reslove.
I have 2 home machines:
MacBook running 10.6.8 (Server / Media machine)
MacBook Pro running 10.7.4 (Client machine). Apple Remote Desktop software is installed on this machine, and connections through it work fine.
A few days ago, the sidebar "Share Screen..." link on the client machine stopped working. All I get is the 'Connecting...' dialog box, endlessly. The bugger of it is that this is only happening with my main account on the client machine. Switching into another (unused) admin account on the client results in the 'Share Screen...' button working as expected.
I've tried the following cures, found on these forums, to no avail:
Reset PRAM and NVRAM on both systems
updated all software
repaired permissions on both systems
changed bonjour names of both machines
rebooter & power-cycled router
killed the NetAuthAgent process a billion times
trashed all of the preferences, caches, etc. for screen sharing and remote desktop in the afflicted user account on client machine
etc. etc.
As far as screen sharing connection options go, these are my results:
using connect to server (via finder > go > connect to server), and plugging in the address (vnc://192.168.0.103): works
launching /System/Library/CoreServices/Screen Sharing.app, and plugging in the above address: works
connecting via the Apple Remote Desktop software: works
using the "Share Screen..." link from the Lion Sidebar: DOES NOT WORK and results in the stall mentioned above, constrained to my primary user account on the client machine.
As mentioned, this was working properly until a few days ago, and stopped spontaneously, with no changes to either system.
Any help finding a resolution to this would be greatly appreciated; this is driving me utterly bananas .

My wife ran into the very same problem today, while trying to connect Screen Sharing to her media center Mac Mini (server) from a Mac Book Pro (client). I was also unable to connect from my machine as well when logged into my usual account but noticed I had no problem with a Guest User account (as you've described), but had also tried most of the unsuccessful attempts at solutions that you've enumerated.
Then, I read this very similar thread: https://discussions.apple.com/thread/4131788?start=0&tstart=0
...and logged out of our now defunct MobileMe accounts on the affected machines. Upon hitting the "Share Screen..." button again, I was now prompted for a local login and password to the Mini, and once that was input, Screen Sharing connected and started up without any problems! Yes!
Given the similarity of our problems, I hope this works for you as well. My best guess is that Screen Sharing might be prioritizing the use of MobileMe authentication over local logins and passwords, and some of Apple's recent work in decommissioning MobileMe had unexpected results for folks like us.

Any ideas? Have tried usual switching on and off again but no change

Here’s what you need to do to turn on AirPlay Mirroring on your iPad 2:
– Have iOS 5 installed on your iPad 2
– Make sure your Apple TV software is up-to-date. You can check for updates on the Apple TV by going to Settings > General > Update Software.
– Have your TV turned with Apple TV active and showing.
– Double-tap the home button on the iPad to bring up the Multitasking Bar.
– Swipe to move to the left of the Multitasking Bar, so you can see the set of controls just to the left of the volume adjustment slider.
– The button just to the right of the Fast Forward button – the one that has a rectangle with a solid, upward-facing arrow in it – is the AirPlay button. Tap to switch from iPad to Apple TV.
– Once you do that you’ll see the Mirroring section appear just below the entry for Apple TV. Just tap to turn that On, and the iPad 2 will immediately begin mirroring to your TV screen.

I am trying to connect my Apple TV to an older Panasonic projection TV using an HDMI to a DVI cable to the Digital IN. I cannot get any sound. Can you help?

DVI interface does't allow audio. Is there optical IN from your Panasonic TV? By then you can connect your ATV to Panasonic using optical together. It will work.

My phone doesn't give me the option to turn mirroring on when trying to connect to apple tv. As far as I can see everything is updated and the AirPlay is turned on. Be grateful if anyone knows what's wrong.

Did you purchase this product direct from Apple online, in an Apple Store, or through a third-party authorized reseller? Or did you buy it from an original owner whose Applecare plan was supposed to be transitioned to a new owner, by them?
Do you have an original shipping carton the unit arrived in?
If the product was a retail 'open carton' purchase and no
back-track is possible, contact the reseller.
And if the computer had seen a major service with logic
board replaced, etc, it may have other issues with serial
number vs one they may have assigned it. Usually a
new logic board may have the SN flashed or if a unit
was determined to be a reman, a new # assigned. But
that would appear in System Profiler, if officially reman.
If you registered a product anywhere with Apple, it would show on a web page along with its serial numbers, going back several years, at this page after you log in there.
https://getsupport.apple.com/GetproductgroupList.action
A blue text with triangle See all products and services opens an Apple ID
sign-in window, then the page changes to show your items & info about them.
If you run the serial number through online Lookup, what appears?

Not sure if this helps, 'your product' should appear - if registered.
Good luck & happy computing!

IPhone is trying to connect to Apple IP-s unsuccessfully

I have iPhone3GS. After upgrade on iOS6 iPhone is trying to connect to Apple IPs. I see the IP address on the router logs, such as 17.149.36.173, 17.149.36.78, etc. One minute escapes 100-200 MB of outgoing traffic. And for two hours the battery completely discharges.
I have an official iPhone, without unlocking, without jailbreak.
I've made reset and recovery from backup. But it doesn't help.
Help me, please

I either get a message to disconnect any bluetooth devices or that the phone of VTech is not on
Where do you see this message?
I cancelled all of this but on my bluetooth setting the device icon is still on and I can't shut it off.
Define "device icon." iPhones/iOS have no specific Bluetooth "device" icons. Are you referring to something you see on the VTech device?

ITunes tells me there is an update (5.1) but it never gets any further than trying to connect to the iPad server. I've tried updating directly from my iPad and it too times out saying it cannot connect to any server. My regular Apple updates work fine.

I haven't updated yet. Apple's download servers have been too busy. Did you know you can update via wifi instead of connection to your computer?
Here's a description of the update. Not a lot of changes for iPad 1/2.

Anytime I open Firefox I get the follopwing meesage: It is storngly recommended that you appl this update as soon as possible. When I trr to di it, it is showing that it is trying to connect to the update server but nothing is happening

Anytime I open Firefox I get the following message: It is strongly recommended that you apply this update as soon as possible. When I try to do it, it is showing that it is trying to connect to the update server but nothing is happening

If there are problems with updating then best is to download the full version and uninstall the currently installed version.
Download a fresh Firefox copy and save the file to the desktop.
* Firefox 7.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Trying to connect to maser xml server.....

running netware 6.5 sp5, zfd 6.5. Getting:
>Trying to connect to Master XML Server...
on the ZENworks Inventory Server screen on the server.
Questions include:
*What's a "Master XML Server"
*How do you make the message go away
If you want to refer me to TID 10099856. I did read that, and it sounds
like the most likely solution. However, I'm unsure where to find a new
ZWS.PROPERTIES or ZFS-STARTUP.XML file. Further, I can edit these files
and they do not appear to be corrupt.
Thanks for your assistance,

Macbook pro keeps trying to connect to an old server

I have a macbook pro, just updated to OSX mavericks, when I turn the machine on, it will keep trying to connect to an old server that no longer exists (a windows pc I had at home I called "estudio"); how can I fix this? where is that the OS keeps the list of servers that the machine has been connected to? I already went through the option of "deleting all the list of recent servers" on the Connecting to a Server window.
Thanks for any help

Why do I get the message "cannot get mail" when trying to connect to microsoft exchange server.

Why do I get the message "cannot get mail" when trying to connect to ms exchange server?

Hard to say. Has it ever worked? Maybe your account has mobile e-mail disabled. Maybe ActiveSync isn't set up properly on the server. maybe the correct ports are not open on the corporate firewall.
You will have to talk to your IT department.
