I just replaced a server (Application/file) in a building running Server 2012. Some computers are on the domain and others are in a workgroup that accesses the shared drive files. All of them access the shared drive files quickly except one computer. It is running Windows 7 with 8 GB of RAM. The computer runs fairly quickly except when it is accessing the shared drive. Again, the others, including older XP computers, access the drive quicker even though some of those are on the domain and others are just in a workgroup. I have run Malwarebytes and it came up clean. Any ideas?
