Event ID: 3000
Source: portmap
Version: 5.2.3790.1830
Message: A Windows subsystem failed a critical request. RPC Port Mapper was unable to start.
   
Explanation

The NFS protocol uses the RPC Port Mapper to enable NFS clients to discover the ports for various NFS services, such as mount, Network Lock Manager (NLM), and Network Status Manager (NSM).

If the RPC Port Mapper cannot start, Server for NFS will not start and NFS clients will not be able to access Server for NFS file shares.

Cause

Windows may be low on system resources.

   
User Action

Try closing programs and restarting Server for NFS. Click Start and then Control Panel. In Control Panel, double-click Administrative Tools, then click Services. Click Server for NFS. In the Action menu, click Start.
