Cannot access NetApp Filer using entry in hosts file

I have a netapp filer named filertemp (192.168.80.2). this is a backup filer. my prod filer is filerprod. If i put an entry in the hosts file of my windows 2008 r2 server that says:

192.168.80.2 filerprod

whenever i use an UNC path (\\filertemp\sys1) it says that the server cannot perform the requested operation. If i use telnet or HTTP and access filerprod it works and goes to the filertemp.

I'm not sure why it wont let me access it. I even setup an additonal NetBios name on the filer using filerprod but it still doesn't let me access.

one thing to note is that our linux servers have no problem accessing it using the name filerprod but having it pointed to the filertemp IP.

See if this helps (on filertemp):

options cifs.netbios_aliases filerprod

Thank you robocat. I did a test yesterday. I removed my DNS servers on the computer i was trying to access the share from. I also clicked enable NetBios over TCP/IP in the network settings. I rebooted and then tried to access the share. It prompted me for a username and password and it let me in. I did this on a windows 2003 server but i could not do it on a 2008R2 server. I guess the security is even more strict (perhaps because of SMB2?).

Thank you for your help. At least i know now that I'm not the only one.
