Unable to install NFS services on Windows 2008

  • Artikel

 

We recently got one issue where the customer was unable to install the NFS services on windows 2008.

On troubleshooting we found that port number '111' was occupied by some other service. We confirmed the same from the 'netstat -ano' output.

The command above gave us the output with the 'PID" running on port 111. Then from the task manager, we confirmed the process name. It was portmap.exe. Portmap.exe from Qlogic (Sansurfer) was running on port 111. Server for NFS is dependent on the portmap service which is design to run only on port# 111. So unless the portmap is running, we would not be able to install Microsoft services for NFS.

There was two options to make it working:

1. Either to uninstall the qlogic service

2. Or to stop the qlogic service and change it to manual.

As per the customer's request, we opted for the second option:

From the Services.msc console stopped the ONC/Portmap service for Sansurfer and changed it to Manual. Rebooted the machine and then installed NFS services.
