I have two hyper-v vm using Windows 11 Pro. as host on same physical machine. I'm executing below command and it works for one of the vm but not the other. I can ping the no accessible vm and remote desktop access that vm. The vm do use differnt [virtual] network adapters [1 1GbE & 1 10GbE] with the 10GbE adapter for the vm that fails.

C:\Windows\System32>C:\pstools\PsExec.exe \\[vm] -u "[username]" -p [password] -s -h -c -f j:\CopyW_DriveBackupToIceDrive.bat -d

The network name cannot be found.
