SMB connections intermittently disconnect
I have an iMac on MacOS Mojave that has SMB connections to our Windows file server. It has been fine up until recently, however. It drops connection every so often and cannot see the server even though it is connected to the internet and on the same local network. It will eventually re-connect after a while, but the drops are very inconvenient and annoying for the user. Usually occurs in the morning and she is the only one having the problem.
I've tried restarting Finder, rebooting, and removing the connection and re-establishing. So far nothing seems to stick as a permanent fix. Any suggestions would be appreciated!
