I'm a remote worker and I have two Windows 10 laptops. Both laptops are connected wirelessly to the same router at home. I log into my personal laptop with a Microsoft account. I log into my work laptop with my company email address. I can also log in to the same account using DOMAIN\USERNAME. Windows Settings shows my work laptop is connected to my company's Azure AD, but it is not joined to the domain. (It is a member of WORKGROUP.) Local Users and Groups does not show my user account, but it is listed as a member of the local Administrators group as DOMAIN\USERNAME. I am able to VPN to my company network as needed, but most of the time I do not use the VPN.
How do I access network shares on my work laptop from my personal laptop? When I try to connect using \\COMPUTERNAME I am prompted for credentials. No matter what I use, I get the error "The user name or password is incorrect." I've tried all of the following:
username@domain.comDOMAIN\USERNAMEdomain.com\usernameMicrosoftAccount\username@domain.comPCNAME\USERNAMEI've verified that I can log on locally to my work laptop with username@domain.com or DOMAIN\USERNAME, so I know I have the correct credentials and password.
