Loosing network connection on one virtual server

Hi,

I am using an ESX Server for virtualizing a CRM 4.0 Server. On the same ESX I have the domaincontroller in another virtual server.
From time to time the virtual CRM Server looses its network connection. It is not possible to ping the server anymore or ping from "inside" the server. The ESX itsself is running fine.
My solution then is to log in the virtual ESX console and open the CRM server in a console window: then deactivate the network and activate again - everything is running fine then for some time.
The virtual domaincontroller is running without a problem.

Thanks for helping.

This is an old problem that seems to come around every now and then. It was previously attributed to the AMD Driver and the VLANCE virtual network card.

Windows 2003 SMP VM with Vlance Adapter lose network connectivity (VM support article ID 1631) http://kb.vmware.com/kb/1631

Ensure that your VMware tools are current.
Additionally, if you have your VM nic set to VLANCE switch it to VMXNET or Flexible.

Hi,

I am using ESX Server 3.5.0, 82663 (SP1) and the nic is already set to flexible :(
Any more suggestions? The problem occured today already 2 times.

Thanks

Please verify that VMware Tools are installed and that you are running the Vmware driver for the NIC.

When I install ESX Server - the tools should be installed with it - or are the tools a special download?
Are they installed on the ESX server or in the vm machine itsself?
