Step 6. Create a user you will use as the user credentials to access your shares with.  This user will need to be created on the both Windows NFS server you have just installed and on the Unix / Linux client you wish to mount the NFS share from.

On your windows machine (harpie in my case) create a local windows user called dave (you can choose your own name of course)  from my Local users and groups tool. I also created a windows group called sfu and added the user dave to it

Create a group called sfu with a group id of 600 (arbitary, you can choose any unassigned number) on your Unix client (rasputin a solaris box  in my case). From the command prompt run:

groupadd -g 600 sfu

Create a user on your unix client called dave and give him a uid of 600 (again arbitary number) and add him to the group sfu. From the command prompt run:

useradd -u 600 -g sfu -d /home/export/dave dave

 Step 7. Create a PCNFS user (dave) and a PCNFS group called (sfu)

-From Harpie the Windows 2003 server open  the Services for Unix administration console.

-Choose  User Name Mapping and slect the Use Password and Group files radio button. Enter a path such as the default one of C:\WINDOWS\system32\drivers\etc\passwd for the passwd (user file) and C:\WINDOWS\system32\drivers\etc\group for the group files.  

-Press Apply 

-Now Create the user and group on the Pseudo NFS server PCNFS - these users will be created in the files passwd and group in much the same way as a standard unix user on a unix OS .

-Under the Service for Unix administration choose the server for PCNFS. Select group from the right hand pane  and create a group known as sfu and give it a gid of 600 

-From the same PCNFS section choose users this time create a user called Dave
