To do so, perform the following steps:
1. Click the Start > Run.
2. Then type regedit in and click OK.
3. Click the plus sign next to HKEY_LOCAL_MACHINE
then SYSTEM
then CurrentControlSet
then Control
then click on FileSystem
4. Right-click a blank area in the right side of the screen and select New > DWORD Value.
5. Give the DWORD value a name of NtfsDisableLastAccessUpdate.
6. Right-click NtfsDisableLastAccessUpdate and click Modify.
7. Then type a 1 in the value data box.

Eureka!
Thanks to querying my problem in “Ask.com” (after bombing out with Microsoft support then wasting much time wading through the results of several different Google searches), I landed at Technipages–what a gift!
I expect it was an automatic Windows update, for the purpose of improving performance, which disabled the File Access timestamp on our workstation/server. For us though, it’s a valuable tracking tool that we were very frustrated to lose.
Thanks to Technipages I found the answer to not only reverse this uninvited “fix” but also an abundance of other Windows tips that had me saying, “So THAT’S what I can do about/to fix that next time it happens!”
