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). |
