Weekly BSOD tcpip.sys+9456b on our SBS 2011 server

Dear support members,

I need your help with fixing a BSOD issue with a server of one of our customers.

I've run dm log collector and attached the zip file to my post.

It is a DELL server but I don't know exactly which type.

We've reinstalled the OS but without effects, we also updated ESXi and VM tools.

The server is virtual, running SBS 2011 standard. (Windows server 2008 is running fine as another VM on the ESX)

Hiya and welcome to SevenForums!
