What i found out is that certain firewall settings have to be enabled. If the target machine is closed off the remote install will fail, what i have done is enabled the firewall settings File and Printer Sharing (Echo Request - ICMPv4-In) and File and Printer Sharing (SMB-In). In our case I restricted these settings to domain only and to a certain network range, but that depends on your network/domain setup.
After these changes, remote installs went fine.
