The WinRM client cannot complete the operation within the time specified.

After configuring WinRM on a Windows 2008R2 server we launched the following command in order to test the installation:

winrm id -r:%machinename%

Unfortunately we had this error message:

WSManFault Message = The WinRM client cannot complete the operation within the time specified. Check if the machine name is valid and is reachable over the network and firewall exception for Windows Remote Management service is enabled.

It was not a connectivity issue because we checked the 5985 port using telnet. We followed the troubleshooting steps described in this post and this technet article. Everything looked ok, no lead so far… So we had a look at the eventlog, and we noticed the following error:

The Event ID 128 in the “Windows Remote Management/Operational” log displays an ERROR_WINHTTP_TIMEOUT. We decided to capture network traffic with WireShark and use the HTTP display filter:

We were a bit confused when we realized that all the HTTP traffic was forwarded on the 8080 port of a proxy server which was on an unreachable subnet… So we launched the following netsh for Windows HTTP command:

netsh winhttp show proxy

And the result speaks for itself:

We were not aware that the server, which was in fact a virtual machine, was deployed with a template having this particular configuration. We did reset this setting using the command:

netsh winhttp reset proxy

WinRM now works like a dream, by the way WinRM clients can be configured to use a proxy server, but that was not what we wanted to achieve at all…

    Thanks a lot, fixed our issue after running netsh winhttp reset proxy. Contacted Microsoft Support and the case is still open and they are still struggling from last 4 days to fix it.
