Hi

I'm having a problem on a virtual machine running Windows SBS 2011 on an Esxi 4.1 machine.

Several times a day i'm losing all of my connections with my server. I can't reach my network shares, can't reach the internet ...

In the event log i'm seeing warning error:

- "While transmitting or receiving data, the server encountered a network error. Occassional errors are expected, but large amounts of these indicate a possible error in your network configuration.  The error status code is contained within the returned data (formatted as Words) and may point you towards the problem."

Log name: System    Source: Srv    Event ID: 2012

I've already tried to delete Vmware tools and reinstall it, i check if the drivers of my NIC can be updated (which is not the case), i disabled the possibility to disable the nic for power saving ...

I've been searching the internet but can't seem to find a solution to this problem.

Can anyone help?

thanks in advance

kind regards

do you have other machines then the SBS running on esxi?
could it be that the sbs runs out of resources for a moment?

also when this happens, can you still ping/access the ESX server itself?

Is this just a single VM or all the VMs?

Is this just the VM ?

Is this host networking okay?

Are you using theVMXNET3 network interface in the VM?

Hi,

The problem has been solved, one of the external parties was testing on the machine with heavy sql queries without even asking somebody which resulted in connectivity issues.

Thx for the help anyway
