Issue on map shared drive to Windows instances, despite configuring Amazon Fsx correctly?

Hello! So I'm following an AWS workshop that involved the creation of an AWS infrastructure that applied Terraform to build it (https://catalog.us-east-1.prod.workshops.aws/workshops/e5122482-ded0-4259-94f0-c373f23c5257/en-US), and since the Amazon FSx file system had already been created and running, I used Fleet Manager to connect to the EC2 windows server instance via RDP and attempt to map a shared network drive on the server machine. However, in my attempts, I received errors saying that "the network path was not found", along with an error code of 0x80004005. I've already verified TCP/IP NetBOIS Helper service already being online and running, along with correctly entering the DNS name that was retrieved from the Amazon FSx console. I checked the security groups too, and didn't find an issue there, since I was able to easily connect to the instance, so I'm not sure what the issue is. Can anyone provide any help or guidance on this dilemma?
