VDI Agent Unreachable - Urgent Help!!

Hi All,

We are working in VDI Environment and using Horizon client 6.2.0 and VMware Tools 10.0.9 version.

Currently we have getting multiple issue that VDI status is showing "Agent Unreachable" and Agent Version "Unknown" in VMware Horizon 6 Administrator Console.

and Tried to ping the VDI same time and it is showing timed out.

Can some one help us to resolve this issue or what is the root cause of this issue.

Urgent Help!!

Regards

Amol
