Snapdrive RPC Error connecting to Netapp from Windows Server 2012

When you try to connect to a Netapp storage from a newly installed Windows 2012 Server you may run into this misleading error. Snapdrive reports that the Storage system is not reachable even though basic networking (ping and nslookup) works.


netapp_rpc_errorYou can see the same error (actually a different error, but it is caused by the same problem) when trying to access the hidden c$ share on your netapp via <netapp_name>c$

This error is caused by the new SMB3 protocol in Windows 8 and Windows Server 2012 which requires signed answers even on older SMB versions!
This signing is not activated per default on the Netapp Filers (maybe this will change when Windows 2012 gets more wide spread), but it can easily be enabled at the Console with

options cifs.smb2.signing.required on

More info on this here and here.

Quick Reminder on bcdedit

For dual (or triple) – boot setups with Windows 7 you will have to change the boot entry and/or the boot order…

To do this, open a command prompt (WITH admin priviledges!) and type


To rename the entry, use

bcdedit /set {GUID} description “Your Boot Entry Name”

to change the default boot os, use

bcdedit /set {bootmgr} default “{GUID}”

The GUID will be shown by the bcdedit command next to the corresponding entry

Use International E-Mail Headers in Outlook 2013

If you use a localized version of Outlook, you will also get localized Message Headers. Especially instead of “Re: <original Subject>” Outlook will add “AW: <original subject>” to any Mail you answer directly….

This is a configurable option which can be switched off, at least for Outlook 2010 and 2013 the Option is located here:outlook_international

For older Outlook Versions, look here
