Hibernate/sleep After 40 Minutes

[therock]

Hello everyone.

 

My name is Jonathan and I have a problem that doesn't want to be solved.

 

I have two W2k8 R2 servers with a Primary and secundairy domain on them. The DNS work great and nothing more is on the server. After a couple of days the two servers were on hibernate or sleep mode.

 

To disable hibernate I used the following command: "powercfg.exe /hibernate off" only it didn't solved my problem.

Knowing that it probally is sleep mode that's causing this problem isn't helping me much. Google gave me some good results but none of those results helped me and power managment was already set on high performance by me. It happends after 40 min. roughly.

 

So my question is how can I stop the servers going to sleep mode or hibernation?

 

I hope someone can help me with this problem.

Do you have a hiberfil.sys file in the root of your system drive? If you do, your system can still sleep and hibernate. There is a tool here for removing it. If that doesn't help, check your BIOS settings and make sure the ACPI power settings are correct. You might have Suspend to RAM or something set that is causing the sleeps.

Yes i know of this and already have used the tool but unfortunatly it wont work. There isn't even a message from the event viewer and because it's not connected through internet and only i have acces there can't be any virus o the system. If there was a virus our enterprise AV would probally have found it.
