Windows 7: Sharing a directory on an external drive

Sharing a directory on an external drive

I have recently purchased a USB Harddrive.

I wish to share a directory on it, but when I tried through the share menu, or by clicking on 'share this' in Windows Explorer, Windows 7 told me that 'This folder can't be shared'.

When I tried the advanced sharing settings, I get an error telling me that 'there are no more endpoints available from an endpoint mapper'.

Other directories, on my internal HDD, are already shared fine, and a quick test confirmed that further shares from the C drive also work.

What am I doing wrong?

I am on Win 7 Home Premium and connect to a router via ethernet cable.

Are you trying to create a shared folder on your windows 7 computer and getting error code #1753 “There are no more endpoints available from the endpoint mapper”. If you are using windows file explorer and just seeing the error text, try running the following from the command prompt:

net share testShare=c:/windows
After 4 hours of searching and finding a zillion other causes for my error I finally found a solution that fixed my flavor of the problem. It turns out to be related to a firewall service issue/dependency. You can probably diagnose your issue just by opening up your services and seeing if you have a listing for Windows Firewall. You may also not be able to enable the firewall from the Control Panel / Windows Firewall admin panel.

Download the following registry files and merge them (double click on the files and accept merge).

With those merged, open regedit.

Navigate to
Right click on it-permissions. (Note: I did not do this step and it still solved my problem)
Click on ADD and use the Everyone group
Select full control.
Now reboot your computer

Hope it Helps..
