I'm on a LAN here at work and I have my desktop sharing some of my project folders. I can access the computer via \\ComputerIP\, but I can't actually open any of the folders. Upon attempting, I get the error:

Windowns cannot access \ComputerIP\ProjectFolder

You do not have permission to access \ComputerIP\ProjectFolder. Contact your network administrator to request access.

For more information about permissions, see Windows Help and Support

Now, this is understood considering I've made it so that you had to utilize the "Project" credentials to connect. I have a user account on my main computer hosting these shared folders that gives full access to the folders if you are this "Project" user. I can Remote Desktop the computer just fine from my laptop using either set of credentials.

When I try to open these folders it doesn't give me the option to attempt to apply any credentials like it does when I remote desktop. How am I supposed to gain access to these folders?
