can't access linux network files from windows using samba

[GarytheGeek]

i have a computer running linuxmint. i want to be able to access its files from my windows 10 pro computer. i decided to use samba. i used this guide and this video to help me setup samba. setup seemed to work fine. i then tried to access the files from windows by typing in \\{linuxcompip}\share in windows file manager. it then asked me to login so i typed in the name and password i setup but then it tells me that windows cant access the files. on this form someone had a different issue i did, but i thought that it was similar enough that i could try it. (bad mistake), i tried this fix and now when i type \\{linuxcompip}\share again, but this time it doesn't ask me for a password, it just straight up tells me i don't have permission to access the files. i tried to reverse what the form told me to do, but i wasn't successful.

 

i tried then to acces it from linux using the method provided in the original guide using the terminal, and i get this

NT_STATUS_ACCESS_DENIED

 

anyone here who knows what i should look at to see what the problem is?
