Event ID 3001 — Port Mapper Startup Status

Applies To: Windows Server 2008

The RPC Port Mapper service enables UNIX-based computers to discover the UNIX-compatible services that are available on Windows-based computers.

Event Details

Product: Windows Operating System
ID: 3001
Source: portmap
Version: 6.0
Symbolic Name: EVENT_PORTMAP_FAILED_REGISTER_UDP
Message: Windows(R) failed a request to register RPC Port Mapper on User Datagram Protocol (UDP) port 111. RPC Port Mapper cannot start. Network File System (NFS) clients use RPC Port Mapper (also known as Portmap and Rpcbind) to discover NFS protocols on remote servers. Without RPC Port Mapper, Server for NFS cannot start and NFS clients cannot access files on this server. Verify that no other software is registered on UDP port 111, then start Server for NFS manually (which will also start RPC Port Mapper).

Resolve

Free port 111 and restart Portmap

To make port 111 available and restart the RPC Port Mapper service:

  1. Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
  2. Type netstat -a -b -o.
  3. Find the process that is listening on port 111. Then, either unload the driver using Device Manager, stop the service using net stop or the Services snap-in, or close the program.
  4. Type net start portmap to restart the Port Mapper service**.**
