Can anyone recommend utilities to measure response time of a Windows Terminal Server?

  • 772

Users are currently experiencing performance problems when using RDP to connect to Windows Terminal Servers. Even users connected to the data centre directly on fibre link are experiencing problems, so I don't believe the issue is the WAN.

Can anyone recommend a utility that shows the ICMP ping time, vs the time to respond to a SYN request on port 3389 (used by RDP). I hope that this would show periods when the whole Windows Server / Terminal Server is slow responding to packets / dropping packets, versus pinging the router on the same LAN.

I understand that this would not be a true "ping", but assuming that if we measured time for a port 3389 SYN to get a SYN ACK response, we could get an indicator of performance. I'd also want the tool to be tidy and properly end the sessions it establishes, to prevent it from becoming a SYN flood DoS attack...

I can see some tools available designed to perform "http-ping" on port 80 to check health of web servers, but nothing for port 3389.

Any ideas on how to monitor this would be greatly appreciated.

    You could try tcping to measure latency to port 3389 of the remote server.

    tcping.exe is a small console application that operates similarly to 'ping', however it works over a tcp port.

  2. It could be a server problem rather than a network problem. My suggestion would be to run PerfWiz on the server and analyze the results with PAL.
