Do you have any idea on this error regarding this. Quick background we have exchange 2013 and we tried to edit /modify the ECP URL's from another exchange server but an error occured below.
"The Version of Internet information services (IIS) that is running on server "EXCH2013".child.contoso.local can't be determined. This error can occur due to network connectivty issues. Check the availability of your network and try again."
Network routing for exchange server are properly working traceble and pingable.
High TCP port are already defined in firewall (High TCP port number between 1024 - 65535)
Opened port 135 TCP
