Ran into a strange problem here, hoping someone can point me in the right direction. We have two Windows 2008 R2 servers that are unable to access a UNC path to an SVM when using the DNS name of the lif. The connection works fine if connecting to the ip address. From these windows servers I can connect to shares by name on other NAS products, and random Windows clients.
From these two servers
\\svm\share$ fails
\\svm.our.dom.com\share$ fails
\\10.1.1.1\share$ works (assume 10.1.1.1 is address of lif)
\\othernas\share$ works
\\windowsServer\share$ works
From other Windows clients \\svm\share$ works
I checked that the Windows firewall is disabled, credentials cache is empty, time is in sync with AD. Flushed the DNS cache too.
So it appears I only have a problem connecting to Netapp CIFS share by name from these two servers. Connecting by ip works, so doesn't look like firewall is blocking me.
I know there is a difference in authentication when connecting my address rather than by name, but the details are not clear to me. Something about NTLM vs Kerberos.
Thanks
