    What about bringing the VHD up on another Hyper-V server?

    Not a bad idea, I'll give it a try, although I don't think the problem is anything to do with the HW, I think its a software issue, something, somewhere, has been changed when the computer last restarted.
    Whether or not it's a coincidence this happens to coincide with updates, I'll never know.

    Good luck with this, and please keep us posted. My Exchange box (2007 on 2008 64bit) is asking for a restart following an update. I think I'll wait.................

    Haha, 2 of my other servers are also waiting for a restart, I'm definately holding off until I've solved the current 2!

    It's not looking good... latest reply from Microsoft:


    Thank you for getting back to me with the information. I am investigating the issue and will get back to you as soon as I have something.

    My first post here but just wanted to share a couple idea's, can you talk to it in safe mode? can you see the ping packets being recived on the server but it's just not replying? Any error logs in event viewer regarding IPSec?

    2 of the VMs on the Hyper-V are the ones with the problem, the 3rd VM is still fine, and just for the sake of testing, I did a full windows update on it and rebooted it, and it's still fine...?

    Thanks for your input Slipbye,

    If I boot it into safe mode, it's still exactly the same situation, can send but not receive, firewall won't start.
    Regarding if the packets are being received, how would your recommend I check that?
    There is an error in event logs regarding IPSec:

    Code:
    Windows failed to apply the IP Security settings. IP Security settings might have its own log file. Please click on the "More Information" link.
    Although all of our servers have this in their logs and it's something we've had for months after one of the Group Policies was deleted.

    Just another update to keep you all posted - I moved the VM onto another Hyper-V server, exactly the same symptoms.

    I also had a look at some of our other Servers and I see many of the also have the Windows Firewall Service stopped and can't be started again - it's very worrying

    Ah, IPSec could easily be the culprit of the only outbound connection issue if it is set to require an encyrpted stream from any external computer. Have a look at the IPSec config and see if you can recreate it or reset it and this may solve your issues:

    Hi Nick,

    I'm starting to think the same idea as theblacksheep in that it might be a corrupt gpo.

    Don't think ipsec is causing it anymore, just wated to test the safe mode idea cause if IPSec has issues it can enter block mode causing the issues your seeing however the service shouldn't start in safemode and as you still have the same problem i don't think it could be that (wouldn't rule out anything yet though).

    I would be tempted to run a dcgpofix however i hate suggesting it as it's one of those "last resort" options that can bite hard if it goes pear shaped.

    I'll have a word with a few mates and bounce some idea's but let us know if you resolve it in the meantime.

    Might be a bit off left field here... (not something a Tory says too often lol)

    someone mentioned IPSec, and I know they use domain certs to authenticate with each other, so i was thinking is it just possible that the servers computer certificate has expired and its unable to get a new one... not really sure where I'm going with this... bit just a thought.. maybe in the AM with a clear head I could say more eloquently.
