I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hello,

I am trying to resolve an issue where multiple client computers in the organisation are using an internally deployed Root CA certificate (before my time and no longer required) to sign the end entity certificate for external websites, google.co.uk
for example. All SSL sites appeared to be affected by this.




However this is not the case as sub domains of sites with issues show the correct cert chain, the below is for mail.google.com




Removing or untrusting this root ca cert breaks access to these sites.

I have reset root certs in various ways, removed machines from the domain, applied no GPOs, manually updated CRL and pulled down updated certs with rootsupd.exe.
It always attempts to use this rouge CA cert to sign the websites cert.

Any assistance would be much appreciated.

Hi,
I am trying to install CA root certificate on Windows 7, IE 9.
Encounter error: "Untrusted Certificate".  "This certificate cannot be verified up to a trusted certificate authority."
I have tried to install the certificate to Trusted Root Certificate Authorities->local computer and import was successful. BUT on IE->Internet Options->Certificate->Trusted Root Certificate Authorities, I am unable to find this root CA on
the list.
On mmc->Certificates->Trusted Root Certificate Authorities->certificates, I am able to view this root CA.
I then restarted the IE and view the ssl site again but failed too, "Untrusted Certificate".
Anyone, any idea ?
Regards,

A:Unable to Install Root CA Certificate - Certificate cannot be verified up to a trusted certificate authority.

May the following workarounds work for you:
Workaround 1:
Modify the Windows settings to allow the Update Root Certificate feature to update the root certificates automatically. For details, see the following Microsoft TechNet article:
Certificate Support and Resulting Internet Communication in Windows Server 2008
http://technet.microsoft.com/en-us/library/cc771121(WS.10).aspx
Workaround 2?
If the Update Root Certificate feature cannot automatically update the root certificates, you may contact the website vender to see if there is a hotfix can fix the issue.

Hi,
I have a successful CA environment working in a Windows 2012 R2-based domain. Recently, some user certificates expired, and when they went to the web page to get a new certificate (https://cert-server/certsrv) using IE 11 on Windows 10 Pro build 1709, they
can go through the pages but the second (https://cert-server/certsrv/certrqus.asp) and third (https://cert-server/certsrv/certrqbi.asp?type=0) pages do not finish loading, no popups asking for permission happen, and when you click 'Submit', you get an error
saying that you can't submit yet because the page hasn't finished loading. (This seems to be a true statement, as evidenced by no list populated if you look at the CSP dropdown box.) This is unique to build 1709. If a user on any lower version of Win 10 Pro
tries the same thing, they succeed in getting their cert.
Has anyone seen this behavior before? It is not a problem with enabling Active Scripting - it is already active. Compatibility mode makes no difference. In our particular environment, web enrollment is the only thing open to us currently. Auto-enrollment
through GPO or other means are not available.
Any help or ideas would be appreciated.

Hiya

All versions of Windows ship with an ActiveX control known as the
Certificate Enrollment Control, the purpose of which is to allow
web-based certificate enrollments. The control is used to submit PKCS
#10 compliant certificate requests, and upon receiving the requested
certificate, stores it in the user's local certificate store.

The control contains a flaw that could enable a web page, through
an extremely complex process, to invoke the control in a way that
would delete certificates on a user's system. An attacker who
successfully exploited the vulnerability could corrupt trusted root
certificates, EFS encryption certificates, email signing
certificates,
and any other certificates on the system, thereby preventing the user
from using these features.

An attack could be carried out through either of two scenarios. The
attacker could create a web page the that exploits the vulnerability,
and host it on a web site in order to attack users who visited the
site. The attacker also could send the page as an HTML mail in order
to attack the recipient.

A new version of the control is available that corrects the
vulnerability, and can be installed via the patch. A patch is
available for all other Windows systems, as discussed in the Patch
Availability section below. Internet Explorer 5 or later is a
prerequisite to installing the patch. As discussed in the Caveats
section, customers who operate web sites that use the Certificate

CNNIC, a certificate authority for the Chinese Government, issued a trusted subordinate (intermediary) certificate to MCS Holdings. This allowed MCS Holding to issue and use a SSL/TLS certificate for any website, but it was expected it would only be used on websites they owned. Instead, it was used internally (and stored in plaintext) to perform a man in the middle attack against all traffic within their company. 
 

 
On Friday, March 20th, we became aware of unauthorized digital certificates for several Google domains. The certificates were issued by an intermediate certificate authority apparently held by a company called MCS Holdings. This intermediate certificate was issued by CNNIC. 
CNNIC is included in all major root stores and so the misissued certificates would be trusted by almost all browsers and operating systems. Chrome on Windows, OS X, and Linux, ChromeOS, and Firefox 33 and greater would have rejected these certificates because of public-key pinning, although misissued certificates for other sites likely exist.
We promptly alerted CNNIC and other major browsers about the incident, and we blocked the MCS Holdings certificate in Chrome with a CRLSet push. CNNIC responded on the 22nd to explain that they had contracted with MCS Holdings on the basis that MCS would only issue certificates for domains that they had registered. However, rather than keep the private key in a suitable HSM, MCS installed it in a man-in... Read more

to start my Outlook 2016 client on my Windows 10 computer on their network, I got the same error.  Two notes are important: 1) I use godaddy as well and 2) I used the same computer at a different client just yesterday without a single error message.

I have some Windows 7 systems which have not run Windows Updates for many years, and cannot due to regulatory reasons.   We rely upon Windows to automatically update the Trusted Root Certificate store whenever we browse to a web site/web service
that uses a certificate the system doesn't recognize. 
Sometime recently, the Trusted Root Certificate Store no longer updates automatically.  The Windows Event Log shows an error stating that the certificates cannot be downloaded from:
http : // ctldl.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab
If we browse to this location manually, the cab file contains an invalid Microsoft certificate. 

This was also an issue in Sept 2018.  At that time, the certificate had expired, and Microsoft eventually updated the certificate to resolve the issue.   This time, the certificate does not appear to have expired.  Why is the certificate
invalid this time, and can Microsoft fix it again?

Thanks

Hi,

Really confusing one here. Since this weekend (16/17 July) we have started getting Certificate errors on some sites and applications. This seems to be due to the structure of the URL compared to the "advertised" name IIS is presenting. I'll try
to explain.
I have a site, Website. This is in my domain, domain.com. Therefore the FQDN is website.domain.com. IIS is running and I can access this site through FQDN,NetBIOS or IP address. Good news.
I create a certificate for the server using the FQDN as the subject, I add the Netbios and IP addresses in the Subject Alternate Names and Bind this to port 443 on the server.
I browse to https://website and all is good. I browse to https://website.domain.com I get a certificate error. Checking the certificate, everything is fine, no errors, chain is trusted. open Chrome and do the same, I get that the certificate website.domain.com
is being presented by Website and may not be the site I want.
Using either URL has never been a problem until this weekend, but it seems that IE/Windows/IIS is not liking any URL that is not EXACTLY what IIS is presenting. so my questions are:-
Is anyone else finding this?
Can we issue a certificate that covers all possible DNS resolutions for a site?
How do I control WHAT IIS advertises itself as?
SO far this has affected two major systems on our network and I can see that more will arise, so any help would be appreciated.

In Internet Explorer, when I get a certificate error, if I continue to the web site, I can then view the certificate to see what was wrong.  However, obviously it would be preferable* to see the certificate
before I make the decision to go to the site.  Is this possible?  I'm sure I could use another browser that does this, or maybe use the F12 developer tools, or write a program.   But I'm looking
for a normal-user way to do it.  I think it used to be possible in Internet Explorer, but this might have been 6.x or even earlier.  Or even
way earlier.  Yep.  I'm that old.  I believe this feature is not in Edge either...unless I'm just missing it.  But I'm using ie11 right now.

Hi,
Having some fun with a windows 7 setup of DirectAccess, have it configured to use ECC certificates on the client for the IPSec authentication, which was working brilliantly, we even have it loaded up behind a Citrix Netscaler to do SSL offloading of the
HTTPS tunnel encryption. But when trying to get Client Preauthentication working, we hit a snag, it seems that the NetScalers dont support ECC certificates, which is a pain, but something we thought we could work around by using an RSA certificate on the client
to performed the pre-authentication (as shown here https://directaccess.richardhicks.com/2016/05/10/directaccess-ip-https-preauthentication-using-citrix-netscaler/).
So we have three CA's, CA1/2 issue RSA certs and CA3 is setup to do the ECC ones, so nice separation of the chains.
So we have our Cert chain for RSA loaded into the load balancer and a new cert issued to the client from CA1... But, every time the client connects to the server (LB) we see the handshake taking place, the server sends a list of its DNs (CA1/2) (https://blogs.msdn.microsoft.com/kaushal/2015/05/27/client-certificate-authentication/)
to the client, but then the client looks in its store, picks out the ECC certificate (issued from CA3) and fails to authenticate saying no suitable certificate can be found, its like its not even looking at the RSA one at all.
So, thinking something was wrong with the way the LB was asking for client authentication, I tried deleting the ECC cert a... Read more

We have a problem where we encrypted files using EFS, however we can't access or decrypt these files now.

We have the certificate in the certmgr.msc but we do see that the key is missing.



I have reproduced this on another computer and was able to run certutil -repairstore -user MY "Serial Number" which worked in repairing the store and files was decryptable again.

However on the machine that encrypted the files that we need to access this is not the case as there is a popup asking for your Smart Card.

We are not using Smart Cards at all, and have had a look at the following article regarding this issue, but the hotfix didn't work: https://support.microsoft.com/en-us/kb/2955631




I have software that can remove the encryption but will require the .pfx file, which can't be exported as the certstore doesn't show that it still has this.



It is a self signed certificate generated by Windows, so I can't request a new one using the CA.


Thanks for your help in advance.

How can I gain access to my encryption keys from my windows backup image or from my windows.old folders? Alternately, how do I migrate the .vhd to a new hard drive and actually boot the darn thing (bare metal recovery)? Isn't that the point of a whole disk image--to be able to back up to a new hard drive when the old one dies out?

Hello, I work at a school where we use a filter program called BlueCoat this filter allows us to filter both http and https traffic. In order to accomplish this we are required to create an SSL certificate and install in on all our local machines. Without this certificate on the local machine the user is unable to use any SSL traffic. In Windows 7 and earlier installing the certificate in the Trusted Root Certification Authorities through internet explorer allowed the entire system to use that installed certificate. In Windows 8 installing the certificate this way only installs the certificate for Internet explorer and programs like the Windows Metro Store and Windows Update will not work because they are not seeing the SSL certificate. Is there someway to install the SSL certificate so the entire system can use it? I also tried installing with the certification manager with no luck.

Since upgrading to Windows 10 a few of our computers have been having issues. Sometimes when they are trying to access a specific website that requires them to submit a digital certificate to sign in it causes their whole system to freeze. They are using
IE11, but because the military likes to use old technology I have it set to run in an IE9 emulation.

I have a Win XP Pro system with multiple users. There are files/folders that I want to start using EFS with.

I am very reluctant to do so because I also want a Recovery Agent Certificate defined so that, if needed, I can user the Administrator account or other designated account as the recovery officer/agent.

My knowledge level is high-beginner/low-intermediate. This means that I've worked some of the tools available in the Win XP Utility box (i.e. Local Security Policy; Computer Management).

What I don't know are the tools required for a non-Networked PC to be able to create MS certificate files (.cer); and then use them when the Recovery Agent is configured in the Local Security > Public Key Policies > Encrypting File System.

If anyone could help, I'd appreciate it. Thank you.

Following numerous failed attempts by McAfee's engineers to install my new virus protection subscription, they told me there was a Windows Certificate error and that I would have to contact my laptop's manufacturers, HP/Compaq.My HP/Compaq warranty ran out in 2016, but having Googled about this problem, I checked in the Certificate Manager section to see whether the certificate had perhaps expired as well ...... but no sign of any certificate at all, despite several years of problem-free McAfee and other installations.My computer is obviously unprotected at the moment and this is worrying.  Has the Certificate disappeared along with the warranty?  Can I reinstate my Certificate?  Ultimately, I need my laptop to allow McAfee to install.Or could the Certificate error be something completely different?Thanks for any help.

I cannot get EMET 5.2 certificate pinning to work in Windows 10.
When I test it by pinning an invalid Root CA certificate to the website, EMET does not block website access in Windows 10 like it does in Windows 8.1
Has EMET certificate pinning been disabled in Windows 10 ? If so, has this functionality been superceded by a better technique ?

I have searched high and low, and this is the only anecdotal reference to this I can find:
"Windows 10 does not use certificate pinning, means someone can easily apply a man-in-the-middle-attack for each Microsoft cloud-access for example"

I tried to change my network settings from WPA2 to WEP last night and like an ***** I screwed it up. I only wanted to change it over temporarily so I could access the wireless network with another device that isn't compatible with WPA2. I ended up having to restore the Linksys router to its default settings. I then tried to recreate the settings it had before with WPA2 before I messed it up. It was on WPA2-Personal, AES, and I changed the network SSID and passwords back from default. Very basic. I didn't set the router up myself originally, though, so there must be something I'm missing.

I am able to connect via Ethernet cable, but when I try going wireless (on both Windows laptops, one XP and one Vista) I get a message saying "Windows was unable to find a certificate to log you on to the network [my SSID]". Most of the searches I ran on Google had people suggesting that I uncheck "Enable IEEE 802.1x authentication" in the laptop's wireless Authentication settings, but that is already unchecked.

Besides, shouldn't the fix have to do with something in the router settings since the wireless was working before I mucked around with the router? The laptop settings remain unchanged from the when wireless used to work so they should be okay, right?

I also tried setting the router up using Wi-Fi Protected Setup, but after the bar loads to the end it says it was unable to connect. Anyone have any suggestions? Or need more info that... Read more

Hi! We've had his issue since the beginning of our Windows 10 migration spanning over five or six Windows 10 builds. Some of our web pages requires to select a certificate on our smart cards but the "Choose a digital certificate" popup window has
since the beginning of Windows 10 appeared behind the IE11 window. This is confusing for the users and I suspect it's a bug.
Anyone have any more info on the issue? Currently we're on 1803 and are running the latest patches.

Hi everyone

Im having some difficulty with a laptop.

It won't update because of error 80072EE2

If I use IE8 and try to go to the windows update site it tells me there is a problem with the security certificate.

I'm guessing this is my problem?

What do you think?

Good day,

I work for a company that uses an ethernet connection and a netgear switch to connect a bunch of trucks together, and then software on the main computer to control all the different trucks and display the data off the trucks, rates, pressures, engine diagnostics etc.

Lately I have had an issue with the software on the main computer locking up. When I checked the event viewer the last couple of times I had a crypt32 error right around the time the software froze. Now I understand why this is happening, because windows is trying to update the root certificates, and I'm not connected to the internet.

The questions I have are:

Do you think it's possible that windows trying to update the root certificates could interfere with the connection between the main computer and the pumps, even for just a split second, to interrupt the software?

And also how would I go about trying to recreate the windows certificate update to see if I can make this issue happen again? Is there a program that runs to update the certificates? I've tried searching the internet and can't find a name or anything. This is the most important part of these questions. Recreating this issue and seeing if it shows up in the event viewer is of the utmost importance to me.

Any help would be greatly appreciated,

Thanks.

Dear All

I am using Hp520 notebook with Win Xp. When i trying to connect to Wi-Fi, the message flash "Windows was unable to find a certificate to log you on the network". I want to get rid of the problem.

I tried the following:
In the authenciation Tab, i tried to uncheck "Enable IEEE 802.1x" bt it is already disabled and also the box is disabled.

A:Windows was unable to find a certificate to log you on the network

Quote:




your wireless router is not setup for certificate security.





Quote:




That's caused by improperly setting the encryption on the Router to WPA-RADIUS instead of WPA-PSK on the client. The router and the client are both trying to find a RADIUS server with which to authenticate. Since you
don't have one, it complains using Microsoft technobabble. Change the
encryption to WPA-PSK (pre-shared key) on both ends.

Sooooo... Here's the problem
 
Two computers, a desktop and a laptop, both running Windows 8.1, both have all available updates installed, both are connected to the same home wireless network.
 
On my laptop, when I access my email in the Windows Mail app, under Settings > Account > Gmail (and Yahoo), it jumps to the bottom of the page under the section for the IMAP settings, where it says: "There's a problem with a server's security certificate." When I click "Details," it says "The certificate isn't from a trusted source. Malicious servers might use fake certificates that cause this error." That's it. No error code. It gives me the option to "Ignore certificate errors," which is "(not recommended)." It seems to be downloading the mail, though, so I'm not sure what's going on.
 
On my desktop with the same Windows account synced over both machines, same email account information, there is no error.
 
I've tried to Google this but I haven't turned up anything. Does anybody know what's going on here? Why are two machines with the same IMAP information disagreeing about the server certificate's authenticity? This is for both my Gmail and my Yahoo account, so I would think it must be Windows.
 
I've restarted the laptop twice to see if it would just go away, but no luck.
 
Please help!

A:"There's a problem with a server's certificate" Windows 8 Mail

 
OK - sorry. As soon as I posted this, I went back to Google and read somewhere online that changing your date/time settings can affect the Mail app's certificate verification and I was fiddling with my clock yesterday. There's a "real time" oriented PC game that I play and I was trying to speed it up.    I guess I won't do that any more...  
 
I removed both accounts and added them back, and the server error is now gone. So, we're good here.

I recently bought two Belkin F5D7320 (v8000, latest firmware) Wireless G routers, and I'm having a very strange problem. I set one up to use WPA-PSK. Using my laptop (running XP Pro SP2), I find the SSID (using the Windows wireless utility), then I double-click on the network. I enter in my WPA key, just like I always would, and it goes through the process of acquiring a network address and all of that, but as it's doing that, I get a bubble alert in the system tray which says "Windows was unable to find a certificate to log you on to the network (SSID)."

The connection seems to still work, though; just I get this message. I have tried a few different laptops, and they get the same message. I have other wireless routers secured with WPA, and I have never gotten that message before using the new Belkin. Out of curiosity, I opened up the second identical Belkin router, applied the same WPA settings, and it seemed to do the exact same thing.

I seriously doubt it's a laptop issue, as I have used the same procedure that I have used countless times to connect to WPA-secured networks, and I have also tried this on a few different laptops, with the same result.

I searched for this message, and people almost immediately suggest that it means either the router or computer are configured to use a Radius server. Well, neither are, as far as I can tell. In fact, here are the settings for my router:

Security Mode: WPA/WPA2-Personal(PSK)

Each WiFi adaptor has it's own setup utility, eg my Toshiba can with an
Atheros AR5005gs onboad chip and the OEM installed its own connection wizard.

Lots of people have used the MS wireless wizard, but perhaps you need to try the
OEM version.
