Network write issue

Hello all,

I have two computers; a desktop and a laptop.

My files are stroed on the desktop (windows 11) and the folder permissions for authenticated users are full access read and write.

The laptop has a lightroom catalogue referencing the files on the shared folder on the Desktop PC.

However, if I am using the laptop, i am unable to complete an HDR merge as i get an error that the final dng cannot be loaded ( there is no file writtent to the folder, even though the wizard indicates the merge is successful).

Any Ideas?
