Eric,
I have read the definition of prepositioning in your post and really appreciate that. However, I do have some qtns on that.
1. proactively "push" frequently used files
qtn. So what mechanism is used by WAAS using CIFS to select which files are to be prepositioned. In my original qtn I asked if I can force a PP so the documention isn't clear on this point. Think about it.. it's a contradiction is statement to say 'Push', when a particular file in a CIFS directory hasn't been access before. In my particular case the CIFS directory is 50GB, and my disk on the nm-wae is 160GB - utilized currently at 50%.
A preposition directive allows you to determine which files should be proactively copied from CIFS file servers to the cache of selected Edge WAEs. Prepositioning enables you to take advantage of idle time on the WAN to transfer frequently accessed files to selected WAEs, where users can benefit from cache-level performance even during first-time access of these files.
2. From the central manager / prepostion settings, should I be able to browse to a cifs directory using this button?. Currently when I attempt to browse it results in a message as follows; 
Could not access cifs://192.130.214.68/
Click the Browse button to browse the directories on the file server. To navigate into a directory, click the file folder icon to the left of the directory name. Check the check box next to the directory that you want to export and then click the Select Directory button. The browse window allows you to choose multiple directories.
3. What else could be done to verify this is working as it should, the documentation appears to be a bit thin on this side.
4. From the cli is there any way to see what files have been prepositioned?
thanks

Based on you drive space (160GB) i believe that you have the NME-522 partition for CIFS cache is 40GB. Pre-positioning data is for transfering a file afterhours which would be required in the remote office. The cache is also for workset and not really for the entire storage that you have.
Based on the rule that you created - it is based on the metadata of the content. The WAE is actually going to the Server to fetch the content via CIFS.

Yes you should be able to browse the directory of the server - Did you add the user information?What about if you try via a name instead of a IP address? Is DNS working on the WAE devices?

there is a status page for the pre-position rule that will tell you the current status of the rule.

no there isn't anyway to look at what files are pre-positioned on the device for security reasons.
Thanks
I hope this helps.
