I'm trying to create a self signed certificate on win server 2012r2 machine using Powershell. The intent is to redirect traffic from HTTP to HTTPS.
a. do we always need a self signed Root certificate before we create a client certificate? If yes, how do we repurpose an existing self signed Root certificate?
b. If we are using the existing self signed Root certificate to create a client certificate, the Powershell commands that I see are not compatible with win2012R2. can someone share the version specific commands?
You can create a self-signed certificate with this command in Server 2019
https://learn.microsoft.com/en-us/powershell/module/pki/new-selfsignedcertificate?view=windowsserver2019-ps
You can try the PSPKI module on server 2012R2
https://github.com/PKISolutions/PSPKI
it contains the command New-SelfSignedCertificateEx that creates a self-signed cert.
A bunch of other methods to create self signed certs: https://medium.com/the-new-control-plane/generating-self-signed-certificates-on-windows-7812a600c2d8
In IIS you need to bind the certificate to your website. The certificate will not be trusted by your clients because it is self-signed. However, you can import the self-signed certificate to your client's local certificate store.
In case you want to build a proper environment, a PKI is needed.

I have DC for development. In DC I have installed Certificate Authority.
Then from web server, in IIS, I'm trying to add server certificate.
In the last step, when I finish the wizard and certificate request is submitted to DC, it is not issued.
When I go to DC, I can see requests under Pending requests. I can now issue or deny certificate, but it is already too late.
Is it possible to automatically issue my requests? Or, can I add the later issued request in my web server?
Double click issued certificate (in DC).
In Details tab click "Copy to file"
Run wizard and export .cer file
Copy .cer file to web server
In web server, in IIS under Server Certificates, right click and Complete Certificate Request…
Import .cer file, add meaningful name
I have this weirdest problem. First off: I'm VERY new to this certificate thingy. I've done a fair amount of searches and reading up though.
The CA Cert that I install into the Trusted Root Certificate
Authorities store in my server automatically get removed/disappeared
as soon as a client web-browser try to connect to a web-site using an
SSL cert created with that CA cert.
DETAILS:
Windows Server 2008 R2 (development server).
I've created my own Certificate Authority Cert; which I use it to generate an SSL server cert (to install on my IIS 7 Server) and a client cert (for use at my local PC to connect to the WCF Webservice on the development server which is set to Require SSL and Require Client Cert).
I installed the CA Cert into the Trusted Root on both Server and local PC.
Installed the SSL server cert into the IIS7 for that particular site and did the https binding to port 443.
As soon as I launch my browser to access that site with HTTPS, the CA
cert in automatically removed on the server (from the Trusted Root
Certificate Authorities store). and my local PC browser will report
an error 403.
This is driving me nuts... anyone knows what is happening?
Apparently, after a lot of running around, it is due to too many of the same certs in many stores.
I open the MMC.exe > Add/Remove SnapIns > Certificates
Notice there are 3 types there (My User Account, Service Account & Computer Account).
Open up My User and Computer Account, go through all the stores for each one and DELETE all of the CA cert with the same name. Then add the CA cert in either My User Account or Computer Account, depending on how you access the certs (in the event of the cert being used programatically, install it in the Computer Account, [Trusted Root Certificate Authorities].
Just 1 place, then the problem will dissappear.
In order to secure my Rest Services, I have enabled SSL in IIS and Created a Self-Signed Certificate and assigned it to the HTTPS binding in IIS. I exported the same as pfx file and added the same in IE also but when I try to access the Services, I get the following error on Windows 7, Enterprise edition
HTTP Error 403.7 - Forbidden
The page you are attempting to access requires your browser to have a Secure Sockets Layer (SSL) client certificate that the Web server recognizes.
And on Windows Server 2003, this is
HTTP Error 403.7 - Forbidden: SSL client certificate is required.
Internet Information Services (IIS)
I am not sure what shall I do except adding the certificate in IE under “Personal” and “Trusted Root Certification Authorities”? Could you please suggest me some step, in order to make this work.
Note: I have tried with “Self-Signed Certificates” as well as with Certificates generated from Microsoft “Certificate Services” also.
Any help is greatly appreciated.
SSL is used to verify the identity of the server, not the identity of the client. The error suggests (http://support.microsoft.com/kb/199215, "This is used for authenticating you as a valid user of the resource. ") the server wants to identify the client. Which of the two are you trying to do?
Edit: SSL requires the public part of the SSL certificate to be available to the client. Adding it to the trusted root certificates seems to me to be the only way to make the public part of a self-signed certificate available to the browser.
Just got my Lync server deployed on Windows Server 2008 R2 and am trying to connect via Lync client on a different machine. When attempting to sign in, the client throws an error saying "Cannot sign in to Lync: There was a problem verifying the certificate from the server.".
Looking deeper, into the client box's event viewer, I see the following error "The certificate received from the remote serer was issued by an untrusted certificate authority. Because of this, none of the data contained in the certificate can be validated. The SSL connection request has failed. The attached data contains the server certificate. ....
My organization has an internal CA, which is in charge of issuing all required certificates to the Lync server. My client box has installed the internal CA (root) as a trusted CA provider. To me, this should cause any certificates that issues, including the Lync certificates, to be trusted.
I installed Lync client on the same box that Lync server is hoted, and am able to log in fine. My error only occurs when connecting from a different box.
Can anyone shed some light? Thanks!
I had same issue. To resolve: from client, hit url of CA Authority, some thing like http://CAservername/certsrv this provided option to download a CA Certificate Chain.
Put this into local computer trusted root certs and I was good to go.
As mentioned in the error message ("Cannot sign in to Lync: There was a problem verifying the certificate from the server"), this is clearly a certification error. If you work in a big company (where they have they own internal CA - (Certification Authority)) in most cases they would have used their internal certificate to establish trust relationship. If you just install/export the Root certificate of the CA under "Trusted Root Certificate Authorities” of “Local Computer” account, this error should be resolved.
If your company doesn't have own CA, then find our who issued the certificate for Lynch and install/export the root certificate of that CA to the same location as above, this issue should be resolved.
