We run a Microsoft Windows network that has a mixture of PCs attached. After the latest Windows 7 updates (mid-April 2018), a tape backup system running on a Windows 2000 Server on the network can see but no longer access files on networked Windows 7 and Windows 10 PCs.
Have the default permissions changed in the latest Windows update, and, if so, how do I tell the Windows 7/10 PCs to give the Windows 2000 Server access to backup certain directories?
