Utilizing your CAC on Windows
10 "can" be as easy as...
Installing the DoD Root
certificates and making sure the
Internet Options are set correctly.
However, computers don't always cooperate with us. So....
Here are my findings and solutions:
Cannot
send email in Windows 10 using Internet Explorer since Microsoft patch
Tuesday around 14 March 2017
Information:
Edge is the default web browser in Windows 10. Internet Explorer
is on the computer and provides backwards compatibility for web pages that do not work
with Edge.
My recommendation is to type:
Internet Explorer into the Search the web and Windows /
I'm Cortana / Ask me anything (box) in
the lower left corner of your screen. Once Internet Explorer appears, right click
Internet Explorer and select Pin to taskbar.
Finding 1: You upgraded
from Windows 8.1 and were using your CAC with little to no problems,
and now you can't access CAC enabled sites. Keep reading for ideas to
try:
Solution1 (built-In Smart Card Ability): Uninstall ActivClient
6.2.0.x or 7.0.1.x by "Right
Clicking" the Windows logo "4 squares" [in the lower left corner of your desktop], select Programs and Features
(now called Apps and Features), find ActivClient in your list of
programs and select Uninstall, restart your computer
and try the sites again. It may work, if it doesn't, try next
Solution. Dual persona (PIV) users might be able to access their
email using the built in Smart Card Ability, your results may vary, if it
doesn't read your PIV, you will need to follow Finding 1, Solutions 2 or 3 below.
Finding 1, Solution2 (ActivID): ActivID
ActivClient 7.1.0.153
works great on Windows 10 computers and is available for
Army users from links on
the
Army page. All other people will
have to get it from you respective branch or purchase it to try it on your computer.
Finding
2. I can't access encrypted emails when using the
Edge web browser
Solution 2:
The Edge web browser does
not support S/MIME. See my recommendation above to see how to use Internet Explorer
to read and send your encrypted emails when using OWA / webmail.
Information
(from
Microsoft): To understand the problem with OWA, Edge,
and S/MIME you need to know the OWA S/MIME is an Active-X
control. By design Edge does not support Active-X (or Browser Helper
Objects); this is good from a security perspective, but bad if you want to use
OWA with Edge. Windows 10/Edge is a work in progress, Microsoft is planning
to use other technologies to replace Active-X sometime in the future. In the
meantime use Internet Explorer 11.
Finding 3. I can't sign
PDFs (Portable Document Format) like I did in Windows 8.1
Solution 3: To digitally sign PDFs, you need to use
Internet Explorer, NOT the Edge web browser, and have
Adobe
Reader set as the default PDF viewer. NO other PDF readers will allow
digitally signing of forms. This
should happen automatically when installing Adobe Reader. However, if it
doesn't, here is how to change the default viewer:
Type:
"default" into the Search the web and Windows / I'm
Cortana / Ask me anything (box) near the Windows
logo at the bottom left of your screen.
Click: Default Programs at
the top of the list.
Click: Associate a file type or protocol
with a program.
Scroll down to .pdf, if it shows Adobe Acrobat
Reader, it is set correctly, if it shows some other program, select .pdf and click the
Change program.. (button) in the upper right corner of the screen.
"Adobe Acrobat Reader" should be in the list of choices, select it and then
OK
Finding 4. How do I get to Internet Options in
Edge? I
can't find it.
Solution 4: Follow slide 5 of
https://milcac.us/tweaks
Finding
5. Cannot see / select the Authentication / PIV certificate in
Windows 10
Solution 5: Windows 10
users will see the certificate selection differently than older versions of
Windows. Click More choices to see additional certificates.
Select the correct certificate and then click OK.
