Cygwin-2.5.0 net share wbadmin no longer working post update

[Alexandria Gutierrez]

I wanted to provide an update in order to help others with the same issue.

We ended up using method 3 from this link:
https://cygwin.com/cygwin-ug-net/ntsec.html

Switching the user context without password, Method 3: With password

Essentially as the user run "passwd -R" in order to store the password
in the registry.
Given our setup this was the best option for us, due to our current
securities restrictions. Keep in mind that this option is most likely
not the best solution for everyone.

Thank you again for the assistance everyone.
