If you’ve tried to map a network drive to sharepoint, and found it didn’t survive a reboot, here’s a Trick a fellow sharepoint person shared with me:

  \\domain@ssl\davwwwroot\subsite\library

In other words, if your site is https://www.mycompany.com/RootSite/Subsite/Library,
to get to that in windows, without opening a browser first, you’d go to \\www.mycompany.com@ssl\davwwwroot\RootSite\subsite\library

Update 6-2014 — renamed article to make it easier to find.

Also, please note, there is the “net use” command which can map a drive from the command prompt.

For example:

net use z: \\sharepoint.yourcompany.com@ssl\davwwwroot\subsite\library /user:domain\user yourpassword  /Persistent:yes

(You can leave off the password part and type it in at runtime)
