I am running windows 10 with our samba server being in ubuntu 18.04.2. The ubuntu machine is on the same domain as the windows computer, but when I go into the file browser to access it, it make me enter my network credentials, which I have tried entering the ubuntu machine login information, a premade domain user, and I've tried making a new user and group just for testing and none of it allows me to enter the folder from the windows machine and it gives me this message picture. Both machines are connected to a windows active directory domain as of now. If this is too vague, please let me know what else to include. Thanks.

Edit1: I have check to see if the computers can ping each other, and the client can ping the server, but the server cannot ping the client.
