Issue/Introduction

 


Symptoms:

  • After taking a snapshot of a 2003/R2 server using Flexible network adapter, the virtual machine network connectivity is lost.
  • Rebooting the virtual machine restores connectivity.
  • Disconnecting/connecting network adapter from virtual machine settings restores connectivity until a snapshot is taken.



Environment

VMware vSphere ESXi 7.0
VMware vSphere ESXi 8.0

Cause

This issue occurs because the flexible network adapter may not handle traffic reliably in newer 64-bit hypervisors.

Flexible network adapters not supported

Resolution

To resolve the issue, change the network adapter(s) from Flexible to VMXNET3 for Windows 2003/R2 server.
