Right click on any one of those images (even tho' it may say "image not located", look at properties, and then look at the path. This will give you a hint on your next step. If you can view images on every other workstation except this main one, then it may be more likely a network connection issue of that main computer. Also, is it just documents? Or is it all other images captured/acquired from other computers?
That's unfortunately for you one of the "tips and tricks" of installing a new server - keeping the server name and paths consistent.
You will need to call Support - there is an Image Move Utility.
I recommend, if you have not already, contact support. There is a utility that can rebuild index within the software. If this is a computer rather then software issue you may need to reach out to your IT as I found solutions to be too broad.
we moved everything to a new server. but the documents were still being written to the old one. so we updated the system path for new images / copied over the folder, but how do we tell softdent to find the images in the new path?
the names of the server paths are consistent. softdent saves / launches off the new server. all of the image files are present on the new server as well. but the path when you click on properties for all of the existing still points back to the old server.
