When I log into my account (Domain) from PC1 and try to access a shared folder present in a Non-domain PC, I am prompted with a window to enter username and password.

But when I log into my domain account from another PC, (PC2) and try to access the same shared folder, I am not prompted for credentials.
I actually do not want to be asked for folder share credentials every time after restart. But I am puzzled why 2 PC’s connected to the same domain exhibit different behavior?
And what configuration/ settings can I compare between PC1 and PC2.
Plus:
*Both the PCs are shutdown every day. No passwords are stored in the windows credential manager of both PCs
The folder share of non domain PC is not configured for anonymous access and will not be done.
Certain GPO policies like Network access: Do not allow storage of passwords and credentials for network authentication is not enabled currently and is managed by the Domain controller*
