We recently installed a Win2019 fileserver on vsphere
Soon after wards we were getting reports of very slow files transfers on all the file shares.
Most but not all PC's were affected,
copying a 1GB file from share to desktop was bouncing between 0 and 3MB/s on a 1GB ethernet LAN and taking 14mins
Logging on to the server and dragging the file off the PC was perfect as was VM to VM (on the same host)
The Solution or rather work around was to go into your adapter settings on each PC and enable "allow other users to connect through this computers internet connection" once that was ticked speed return to normal. The other Adapter is not connected to anything.
Anyone know a better way to resolve the issue ?
