windows 10 – Unauthenticated Guest Access error when accessing file server

With this latest windows update, I have been seeing an influx of this error when my users try and access a mapped drive, or even a direct connection to the server hosting the mapped drive:

You can’t access this shared folder because your organization’s
security policies block unauthenticated guest access

Most of the time I can go into the Group Policies, Security policies, or the Registry and set the Lanman Workstation values to Allow Insecure Guest Access. However, I have one workstation that will not connect for some reason.

so far I have done the following:

  • Edited the security policy to allow insecure guest access in the Lanman workstation.
  • Edited the group policy to allow insecure guest access in the Lanman Workstation.
  • Edited the Registry to allow insecure guest access in the Lanman Workstation.

Specifics about the Workstation

  • Windows 10 with the most recent update pack.
  • Refuses to find the network with a static IP.
  • Will only connect to the network via DHCP
  • when trying to domain the computer it will not find the domain server using DOMAIN, and DOMAIN.LOCAL does not exist for it.
  • File server is Linux Based

Has anyone run across this issue? is there some insight that I’m missing? I’m a Jr. Administrator and am still learning.
