Event ID 1071 — NFS Port Registration

  • Article

Applies To: Windows Server 2008 R2

Network File System (NFS) clients discover NFS servers by querying the port mapper for a remote server. RPC Port Mapper converts RPC data into TCP and UDP protocol port numbers. It must be active for Server for NFS to start.

Event Details

Product: Windows Operating System
ID: 1071
Source: NfsServer
Version: 6.1
Symbolic Name: EVENT_NFS_NSM_SPECIFIC_PORT_RPC_REGISTRATION_FAILURE
Message: Server for NFS could not register the Network Status Manager (NSM) protocol on the specified port. Server for NFS did not start. Without the NSM protocol, NFS clients would not be able to reclaim files locks on this server, if either the server of client's service is disrupted. Verify that no other programs are registered on the specified NSM protocol port, or use the Nfsadmin command-line tool to specify a different port.

Resolve
