Has the 'address' URL for a server share always been in the following format?
file:///svr-fs1/engr/Bearing%20Life/Model%20Bearing%20Chart/3p.pdf
This Microsoft support ticket seems to describe the situation pretty well:

If the address URL could be changed to be exactly how I type it into the wiki page then it seems like it would solve the problem.
Thanks a head of time for any responses.
