[snichols] Below is the sources to a small application to quickly disconnect and 
reconnect all network drives for Windows operating systems. 
This application is handy if you need to quickly disconnect and then reconnect your drives. 
I’ll use it mostly for when I VPN into other sites or my laptop is not on the network. 
Otherwise the persistent drives slow your computer when it does not have access. 
Please use this application at your own risk. Please let me know what you think. 
Special thanks goes to kbk and dgp for their coding examples and use of regular expressions 
and the examples of use of Window's Net program.

[pcam] Nice and useful tool, that I shall be using often, thanks.
One thing though I would remove the line calling for tile (and the category, sorry Larry) as it is not needed I think.

[LV] At first I misunderstood your comment. After starting to reply several times, I figured out that your meaning was probably ''Tile is the old name of the new widget set - you should be referencing ttk instead.''.

[pcam] In fact, I meant, that this code despite loading the tile package, and using the tile namespace does in fact not need any Tile feature. I tried it without and it runs perfectly. All that for the purpose of running on older versions. Well I leave the code as is, that was just a comment. Also this means this is possibly not the best example of using tile either (maybe the category using tile is not appropriate). BTW thanks for adding these categories, as they become more useful as the wiki grows. 

[LV] Okay - I hadn't tried to run the program yet, so I didn't know that it didn't actually USE tile. You are right - if a program doesn't make use of the package, then not mentioning it might allow it to run on older versions of Tk. Perhaps the developer did it this way so that, in the future, if someone included one of the widgets in use in [Ttk], it would be used by his program automatically.
