Os is Server 2012 R2 Standard Owa Fails to load site internally. Always seems to load ok externally. We do use a proxy server ( Smoothwall) We do bypass local addresses Pretty sure county NAT OWA and the only port open is 443

No One server is running all roles ,Cheers

We are running CU6 with around 1500 mailboxes. The server has 10 cores and 16gb of ram as it seems to love ram! Cheers

Hi All, We have been having some issues with our exchange 2013 box lately. When a user tries to load OWA they have to try around 3 times for the page to load otherwise they get "Webpage Unavailable" . This is just to try and load the OWA Login page. Once they have it loaded it runs fine and they can close the browser and reopen and its fine but its the initial loading of the login page. It doesnt matter what browser they are using it happens on both Google chrome and Internet explorer. Anyone else had this before? Thanks

Hi all, Managed to get this sorted out (Touch Wood). The issue was with the network drivers and Virtual Machine Queues. Once i had disabled this the CPU dropped. All has been fine since monday. Thanks for you help !

Managed to solve this, I had joined two hyper v hosts to the same ISCSI device and volume when they were not clustered. Currently Microsoft doesn't support that sort of use as it must be clustered. Thanks

Thanks for Your help guys, Managed to sort it (touch Wood). We have been having issues with our file server and with several attempts at fixing that i ended up with 4 dns records for the file server and somehow 6 for our domain. Once i cleaned those up it seems to be working okay. Been okay since Monday morning. Thanks all

Would i run the performance analyzer on the client machine?

Disabled virtual machine Ques to lower the cpu but now when I enable it the cpu doesn't go up again. Event viewer has nothing in it.

Hi All, I am currently testing our new file server after issues with High CPU. I have managed to lower the CPU but now when users are logging in the logins take ages. Most of the time is spent with a little box at the top left "setting up personalized settings" Any idea if this is related to the file server or something else? Anyone had this before? Thanks

HI all, I have two hyper v hosts connect to a dell ps6100 SAN using iscsi initiator. When i set it up i have to connect the hosts to the san and then mark the volume as online on both hosts. Now on the one host i am getting errors about the ISCSI drive "Online Scan Needed". These repairs seem to happen automatically as i can see in the logs the following. "The file system structure on volume D: has now been repaired." Any idea why this would be happening? Is it because i have two hosts connected with the disk marked as online? Do i need to stop the server from automatically repairing them ? Thanks

Did you ever manage to repair the corrupt VHD? Cheers

surely there has to be a way of seeing what is using it so much.

Any tips on finding what that process is ?

Just looked at our CPU usage on the file server again and we are back at square one. Its gone sky high again! I have used process explorer to look at the threads being used by the system process . Take a look at the screen shot. No idea what the thread is doing though.

managed to update the drivers and i now have a steady 1-3% cpu with a hand full of users on the server. Guess its a waiting game until tomorrow. Hope its fixed the issue

Was it giving you a high System Process reading?

Im currently on Version 12.11.97.1

Could you find me the link you used or version you are running?

I have just disabled the network adaptor and the CPU hit 0% and is fine so it must be NIC related ? Or is it just because no one is trying to browse files?

The storage is provided from a Dell SAN through 2gb ISCSI connection.

The Nics are intel I350 . Sophos is excluded from running where the VM's are stored.

Shaddow copies is enabled, Automatic maintenance is set to run at 2am in the morning and search optimization is not enabled. Hope this helps

I will only assign it 2 cores shortly. Here is the Host Spec

I have disable DeDUP but the issue seems to still be there. I have only allocated it 4 cpus with 6 gb ram and this is still happening. When i use the process monitor all the usage is assigned to System. Any other ideas?
