High ping response RDS during day time

Hi Experts,

I have a strange issue with my RDS server. It''s a Windows 2008 R2 machine with remote desktop services running. Probably about 15 users use this server by connecting with their thin clients. It's a virtual machine running on a stand-alone Hyper-V host.

When i ping from the RDS to another server in the network, i get high latency response of between 200ms and 400ms. When i ping from another server to the RDS, the response is 1ms.

When i do the same at night, the response is normal. I deleted the virtual network card and ataached a new one. This didn't resolve the problem.

Any idea how i can troubleshoot this issue?

I would setup a packet capture to see when it looks like the ICMP packet is leaving the RDS server.

What is the CPU utilization on the RDS server?  Could be that it is prioritizing the ping cmd very low and so it is delaying actually sending it out, but it may not do anything for inbound ICMP packets.

However, other than the high response for outbound ping's are you seeing other problems?  Personally unless you are doing this to figure out another issue I would ignore the high ping response times.

RDS is traditionally complicated to troubleshoot. Id suggest you install the free trial of controlup and see if it gives any insight to what is stressing the server during the day

Specifically you can look into sessions, gpo load times, disk queue length, etc...

icmp is a low priority stateless mechanism.
