[ed note: https://code.google.com/p/dart/issues/detail?id=9238]

The web samples do not run because the packages do not get built. On Win7 box with SAN back end which has caused issues. Am I still pointing to some strange UNC path or synonym?

Here is the error shown in dart editor -
Failed to load resource: the server responded with a status of 404 (Not Found)

My guess is the issue here is that Windows junction points do not work with network shares and cannot span drives (you can't have a symlink in one volume that points to a directory on another).

I'm not sure how we can address this, but I'm open to ideas.

Is the D: drive a remote drive of some kind?

The Windows junction points used by pub for the package structure are only supported on local NTFS volumes.

From the report it is difficult to see whether it is the packages that are not correctly set up.

To check whether there is an issue with junctions run the following in a command prompt:

D:
cd /Users/michaelg
type con > testfile
1234
^Z
mklink /J testjunction testfile

To check whether a symbolic link might work run the following afterwards in a new command prompt running with administrator rights (select "Run as administrator or use SHIFT + CTRL when starting).

D:
cd /Users/michaelg
mklink testlink testfile
