Some ports used for Services for Network File System are closed in Windows Firewall.

Users will not have predictable access to shares when using the Network File System (NFS) protocol.

Use Windows Firewall to open the appropriate ports.

Services for Network File System automatically opens the appropriate ports by default. If you change the default ports, you must manually open the appropriate ports in Windows Firewall.

Membership in the Administrators group is required to complete this procedure.

  1. On a server running the User Name Mapping service or Services for NFS, click Start, click Run, type firewall.cpl, and then click OK.

  2. Click Advanced Settings and in View and create firewall rules, click Inbound Rules.

  3. In the Action pane, click New Rule.

  4. In the New Inbound Rule Wizard, in Rule Type, click Port and proceed through the wizard.
