I am attempting to install the Network Policy Server role via the Add Roles and Features wizard, which is being run remotely from a management station (i.e. not on the server itself).
It tells me I need to specify an Alternate Source Path for the installation files. I have tried:
WIM:\\ad.lifeway.net.au\shared\lifeway-gpo\en_windows_server_2012_r2_x64_dvd_2707946\sources\install.wim \\ad.lifeway.net.au\shared\lifeway-gpo\en_windows_server_2012_r2_x64_dvd_2707946.iso \\ad.lifeway.net.au\shared\lifeway-gpo\en_windows_server_2012_r2_x64_dvd_2707946\ \\ad.lifeway.net.au\shared\lifeway-gpo\en_windows_server_2012_r2_x64_dvd_2707946\sources\ \\ad.lifeway.net.au\shared\lifeway-gpo\en_windows_server_2012_r2_x64_dvd_2707946\sources\SxS\
None of these are working - the wizard just bombs out telling me it can't find the source files required.
What am I missing here?
This is a Server Core installation, and I have tried it via PS as well:
