Windows Server 2008R2 NFS Export to ESXi 5.0

Hi, I am trying to access some NFS shares on a Windows 2008R2 Server VM to ESXi.  I have set root read/write ALL MACHINES access and tried both allow unmapped users and allow anonymous access.  But on ESXi, I get there error that the mount request was denied by the NFS Server.  This used to work, but I changed the IP address of the Windows Server VM and now I can't get it back.  Thanks for your help.

are you using hostname or IP address to mount the export?

I've covered this topic here, in some Tutorial Videos I've created for EE Members

Video Tutorial - Creating an NFS Datastore using Windows 2008 R2 for VMware vSphere ESX/ESX 4.x

Video Tutorial - Adding an NFS Datastore to a VMware vSphere ESX/ESXi 4.x host server

although written for ESXi 4.x, the same works for ESXi 5.x.

no need to use user mapping.

do you have vmkernel portgroup?

firewalls disabled?

can you vmkping the nfs sever?

can you connect to the windows server from another windows machine to check nfs connectivity?
Hammer8Author Commented:
OK, tried to perform your checklist:

1) not sure what this means
2) yes, have vmkernel portgroup
3) firewall allows nfs server
4) I can vmkping the server with the nfs shares
5) I tried to connect to the nfs share from a windows 7 pc and get an error 53.  I can however, ping it and rdp to the nfs server

Thank you again for your help.

1. user mapping is not required to be configured in R2 as you can see by my video its not enabled to provide nfs.

5. okay so issues is possible not ESXi, but NFS configuration.

I have reviewed my NFS setting in Server 2008R2:

Alias = NFS
Path = S:\NFS
Supported security flavors are SYS
Encoding = ansi
UNMAPPED UNIX USER access allowed
ANONYMOUS access disallowed
Anonymous UID = -2
Anonymous GID = -2

ALL MACHINES            read-write     Root Access Allowed      ansi

This seems correct comparing to other sites.

Any thoughts?

Hi, thank you for your help.  I found the problem - it was because before I realized I had an issue with NFS, I installed Veeam Backup on that server.  Uninstalling it allows NFS to work again.  Much appreciate your time and help.
