Article's link still is broken. It targets http://www.sqlservercentral.com/articles/%23Vcenter+%23Shrinkdb+%23VIM_VCDB+%23VCenterservice/152481/. So, based on other article links that do work, I removed each "%23" yielding http://www.sqlservercentral.com/articles/Vcenter+Shrinkdb+VIM_VCDB+VCenterservice/152481/ and still no progress.
By the way, as soon as I logged in, the system yielded this:
An error occurred
There was an unexpected error. If you keep seeing this message, contact the board administrator.
I was still able to navigate once in.
