Question : I can't attach a NFS datastore fom a netgear NAS to an ESXi 4.1 server

I have a Netgear ReadyNAS 1100 NAS where I have set a NFS share so I can add a Datastore on my ESXi 4.1, I used the following instructions in their site: http://www.readynas.com/?p=3030

Every time I try to attach the NFS share through the GUI i get the following message: "Operation failed, diagnostics report: Unable to complete Sysinfo operation.  Please see the VMkernel log file for more details."

I have also tried through the SSH console by using the command:esxcfg-nas -a -o 10.0.0.10 -s /share/mynfs mynfs and I get the error:
"Connecting to NAS volume: mynfs
Unable to connect to NAS volume mynfs: Unable to complete Sysinfo operation. Please see the VMkernel log file for more details."

the Kernel log details are:

Answer : I can't attach a NFS datastore fom a netgear NAS to an ESXi 4.1 server

Guys, Unfortunately the answer was to set the static IP address to DHCP on the NAS so the DNS will auto populate, it does not make a damn bit of sense but it worked thanks to a VMware forum person named Joe who suggested I check on my DNS settings (Head scratching). you can check the thread here at:

thanks everyone.
