We are experiencing a situation where we have 4 Hyper-V virtual machines on a VLAN-A that also contains a few physical servers. The physical servers have no problem but we are seeing continuous intermittent connectivity on all the virtual machines. For example on any of the VMs, I can query AD now and then get an error that no domain controller available if I try again in a few minutes, Opening ADUC received errors. On the physical servers none of these errors is visible so we can't really say if it is an AD or Hyper-V issue. Also if I move the virtual machine to another VLAN-B it works perfect with no issues.
A good example of one of the issue, I installed the AD replication tool on one of the virtual machine. It fails to run every time on VLAN-A but as soon as I move the virtual machine to VLAN-B the tool runs perfectly with no error.
Not sure how to diagnose issue like this.
Thanks
