"The operation is invalid on a redirected resource." when "net share" of Dokan drive

[epa]

Hi, I have a Dokan filesystem running on drive N:. I would like to export it as a shared drive from Windows.

net share myshare=N:\

But with my current Dokan filesystem this gives the error

The operation is invalid on a redirected resource.

More help is available by typing NET HELPMSG 2117.

However, using the example mirror filesystem from the Dokan-dotnet sources I am able to export it as a shared drive. I'm trying to hunt down the difference between my program and the example to see what particular setting causes the problem, but so far I'm a bit stumped. Has anyone seen this error before, or have any suggestion about mount options, etc, that might cause it?

I have worked around this by specifying the mount point as a subdirectory rather than a new drive letter (so C:\mydir rather than N:). That requires the MountManager Dokan option. Then this subdirectory can be exported with net share.
