|You must ensure both laptops have the same workgroup name and are connected on the LAN (local area network). Once they are you would then need to share resources on one or both laptops. It's recommended that you create a user account on the unit with the share for the unit that will be connecting if you don't have identical login credentials for both.|
For example, if you use exactly identical credentials to login to both laptops, you won't need to create special user accounts:
Unit 1 and Unit 2:
If however, you have different credentials:
You would need to create an account on the target unit. For example, you share a folder on unit 1 and you want to access it from unit 2 you would create a user account on unit 1 with the following:
You would add that to the ACL of the share and give it appropriate permissions.
The reason for this is, if you don't have an account, then you will be asked for a password whenever you connect to the share.
