Thanks Alan, with regards to the files, we have a sharepoint set up but due to handling very large files (working in video and image editing) the upload and download speeds really hinder productivity. We have introduced a NAS which is currently just shared with the video editors over our local network, but setting this up was a bit of a trial. but from how I understand it a domain network would make management easier. Ive moved into a new role here so Im just trying to get my head around everything, but there are a lot of best practices that are not being followed (lowest privilege for example) and thought that migrating to a domain would streamline the management of that, rather than going to each pc individually and changing user permissions.
365 business premium is one route we are considering, but the cost compared to the business license is a bit eye watering, and the p1 comparatively was very cheap. Although it seems that I was misunderstanding the services they offered.
If it clears things up this is my first IT role, after completing the COMPTIA A+ course, I'm the only IT admin here so having to figure things out as I go.
