File Copy or Delete is Stuck at 99%

Troubleshoot an issue where a Windows mounted file system cannot complete a copy or delete operation.

Symptom: When you try to copy or delete a file in a file system mounted on a Windows instance, the process gets stuck at 99%.

Cause: By default, a Windows instance tries to access a mounted file system using Server Message Block (SMB) ports 139 and 445. Since File Storage file systems use an NFS mount, the process fails.

Solution: Reorder the network provider list to place Nfsnp first. Follow the steps in To change the network provider order on Windows 2012+.
Important

Reordering of the network provider list requires a system restart.
