Solved: Renew mail certificate

Q: Solved: Renew mail certificate

I've got a warning on my ISA server that my mail certificate is going to run out in a months time.

I've been reading posts saying that I need to go into certificates, current user and find the certificate, however for this particular one, on all of my servers apart from my main domain controller, the certificate authority pops up saying 'the specified service does not exist as an installed service'

When I load up the certificate authority on my domain controller, I get a different view and not the current user/personal and so on, but revoked/issud/pending and so on.

I can however click on the main section of this (domain name) and right click and all tasks, renew, but it warns me to stop the certfication service. Not sure if this is the right way to do it.

Can someone advise please.


Preferred Solution: Solved: Renew mail certificate

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.)

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.

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 ?

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
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.

My yahoo program works ok except for email. When I click on the email icon, I get the following message:
"The security certificate presented by this website was issued for a different websites address."

Then it gives me a choice to still retrieve my mail with a warning.

Is this a problem at Yahoo's end or at mine. Is there something I should check?
Internet Explorer is 32 bit while Windows 7 is 64 bit. Does this make a difference?

A:Yahoo Mail Certificate Error

I think I solved it. Under tools and the advanced tab, I scrolled down to Security to where it states:
"Warn about certificate address mismatch".
I unchecked it and now the certificate error does not appear.
There is no evidence that my computer has been hacked or has a virus and this particular error is suspected of being no more then a false positive brought on by "Yahoo".

I am trying to get email to work on a new RCA tablet, for neighbors.
The browser - Chrome - on the new tablet with Android OS - works wonderfully well when browsing, but when trying to access web mail (same ISP), there is a message saying that the site is dangerous, or that there is a problem with the certificate(s) and/or that the connection is not private. However, when going to the same site on their desktop PC and using Thunderbird to read their mail, there is no problem, whatsoever.

There was a message saying that the gmail application could be used with non-Google addresses, but that did not work, either, despite having checked with the ISP as to the addresses for the incoming and outgoing mail servers.

Is there a dependable Android email application, that someone can recommend, without my having to go through the list of over 250 email programs available on GooglePlay?

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!

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.

For the last week, I am getting the error msg pop up below whenever I open PostBox mail reader.  Doesn't appear to affect anything - just annoying.  Plus I worry that it might be some type of malware.
I am running Windows 7 Home.
Thanks for any help.  
This is the error msg pop up:
Server connection failed
stats.g.doubleclick.net:443 uses an invalid security certificate
The certificate is not trusted because the issuer certificate is not trusted
(Error code: sec_error_untrusted_issuer)
This could be a problem with the server's' configuration or it could be someone trying to impersonate the server.
If you have connected to this server successfully in the past the error may be temporary and you can try again later. 

A:Certificate error pop up when I open mail reader

This issue isn't indicative of malware. What it means is that the website or server is not authenticating properly with it's SSL certificate or has an invalid certificate.
What this means for you is that you cannot trust the connection. You should not use it for sensitive information or banking of any form.

Question and possible solution (Nothing like answering your own question, eh?)

Recently I've been seeing an old problem recurring lately (I've read the posts on here from 2009 or so and others) :

I'm using XP and IE8 for certain reasons on a laptop in my home studio.

Annnd, my time and date are fine on my laptop.

So..all that said, and while trying to hit https://gmail.com I get the standard:

*** There is a problem with this website's security certificate.
The security certificate presented by this website was issued for a different website's address.
Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server.
We recommend that you close this webpage and do not continue to this website. ***
First, here is my solution which is more of a workaround IMHO: Simply use https://accounts.google.com

That will avoid the certificate warning and take you to basically the same desired destination without the grey hair and fingernail biting.

But my concern remains: The 'fingerprint' of the security certificate (I list the results and id's below) of https://gmail.com (on my "clean" machine anyway, does not match the landing page where I wind up...which is https://accounts.google****blahblahblahcodecodecode.

If I ignore the warning and, "continue to website (not recommended)", I see the friendly familiar (real?) login page.

But the thumbprint of the page does NOT match... Read more

Please read it before start: Free Secure Email Certificate

These days when e-mail has become the main means of personal and business communication and stealing information is what trade secret crimes thrive on, the problems of securing email and safeguarding privacy are on everyone's mind.

Even if your job does not imply sending your company's secrets that need to be protected from unwanted eyes, you may look for a little personal privacy. Whatever your reason is, the most reliable ways to secure your communications with co-workers, friends and family are mail encryption and digital signatures. Outlook email encryption protects the contents of your messages against unauthorized reading, while a digital signature ensures that your original message has not been modified and comes from a certain sender.

Encrypting email it Outlook may sound like a daunting task, but it is actually quite simple.

I am not sure but you can try the similar steps on Thunderbird to use the certificate on your mails.

A:Solved: Cant renew IP address

(from a JohnWill post)

IP addresses of are normally caused by one of the following.

1. DHCP Service not running.
2. Duplicate IP address on the network.
3. Bad NIC card drivers.
4. Defective NIC hardware.

1. Check Control Panel, Administrative Tools, Services. The DHCP Client service should be Started and its Startup Type should be Automatic.
2. Turn off ALL of the computers and other network connected devices, reboot the router, then restart all the computers and other network devices.
3. Check for upgraded drivers and/or reload the Network drivers.
4. Replace the Network Interface Card.

I hope this is the correct forum for this issue? My Dell laptop will no longer connect to the internet and the issue I'm receiving is:

"Windows could not finish repairing the problem because the following could not be completed: Renewing your IP Address"

I've run multiple scans on the computer with 3 different programs so have determined it does not appear to be any sort of malware issue but either a windows issue or hardware issue? When this first occurred I performed all the usual steps for repairing the connection, rebooting the router/modem, running IP config to make sure it was even showing up, direct connecting to the router, malware scans, removing dead networks from the auto-connect list, checking TCP/IP properties, checking ipconfig, looking at router settings to make sure nothing is turned off, all to no avail.

I don't know if I missed anything in the areas I looked at, or if I am just looking in all the wrong places.

Please advise what further info I can provide so you are able to help me resolve this and thank you for your time!

The computer is a Dell Inspiron E1705 with XP Media Center Edition version 2002, Service Pack 3.

You wanted your IP to change with the /renew? It is possible your router has MAC filtering set up so that your NIC will ALWAYS be assigned the same IP address.

I just recently developed this new problem with my PC Windows laptop sp 3 that is going to be the death of me. The wireless internet won't connect because I have an invalid IP address. I called Comcast, who directed me to the command "release/renew". "Renew", however, came up with this error. "An error occurred while renewing interface WIreless Network Connection: The RPC server is unavailable." So I go to services.msc, but my RPC is started (tidbit: the RPC locator is off, but I don't know what that's for...). After surfing online for solutions, I saw that DHCP Client, DNS Client, AFD, and TCP/IP NetBIOS Helper had all be started. Well, DHCP Client and TCP/IP NetBIOS Helper won't start because of the same reason. "Error 1075: The dependency service does not exist or has been marked for deletion". So I asked myself, what dependencies? I checked, and both of them need the AFD to be started. So I looked in services.msc, but there is no AFD. Is that supposed to happen? How do I fix this? Please help!

P.S. My router and modem both work perfectly as I have other devices that are wirelessly connected to the network fine.

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.
2) They use POP 995 w/ SSL & SMTP 465 w/ SSL to pop.secureserver.net & smtpout.secureserver.net repsectively

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?

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.

I have two PCs in two different locations of the neighborhood and each with a different Internet provider. Both are served by a radio link from the respective (different) providers (Antenna on the roof, Modem DSL box inside, Ethernet cable connection to PC).

The trouble arises at one location where the connection sometimes goes down briefly and then is back up but sometimes is gone for good. The provider then advises to cut off the mains power to everything (modem box, PC etc) and reconnect after a couple of minutes.

It usually works but sometimes it doesn't at all. Last night 3 times had no result. I contacted the Provider this morning who told me to disconnect/reconnect again and this time it worked. But he told me that they had done nothing their end and that the PC here had failed to renew DHCP lease. I understand what that is but my PCs at the other location have never had that issue (DHCP change is not so frequent with that other provider but this one here is expanding his customer list).

What bugs me is that the net goes down frequently with this one during a session but then comes up again, presumably renewing the DHCP lease all the time. Takes a coupla seconds, half a minute at most (DHCP changes quite frequently I know from a neighbor who often runs the config command).

I'm leery of the (usual) provider take that the fault lies/lay at my end.

I've only been working on this one for about a week so I don't know the provider's track record... Read more

Hello everyone,

Yesterday i reformatted my hard drive in my computer that was running windows 2000 pro. (some of you are familiar with that one as i have about 6 threads on problems i had) anywayi then installed windows xp home. When i got back on, i was trying to setup my internet connection because the settings were erased with the reformat and i couldnt get online. I tried to get to the site for the router setup ( and it wouldnt go, it said internet explorer could not open the search page. Then i went to release and renew the ip and when i try to renew my ip it says it cant. then i tried to repair the connection and it says cannot renew ip config and some other thing. It also shows my ip as (or something of that sort)

so last night after rebooting (the computer froze ) when it loads up, the background of the desktop shows up but nothing else. i can only get to task manager aka. ctrl+alt+del. please help! (i will go check now if the desktop still isnt showing up while i wait for replys)

also, when and if we fix this, should i go, first thing, and dowload all available updates (and sp2) before reinstalling all of my old programs?

A:Solved: cannot renew ip, and desktop not showing up...(just reformatted!)

I'm trying to set up a wireless network with an Actiontec DSL modem/router. I have internet access on the computer connected to the modem, but can't connect on the other two PCs, despite the fact that they both say they're connected to the network. One is a Sony Vaio, the other is a wimpy little eMachines t1115. The Vaio is wireless ready, but keeps telling me that a network cable is unplugged. The eMachines is connected with a Belkin USB wireless adapter. Cannot ping either PC; both have weird IP addresses...169.254.x.y. Cannot ping router/modem from either machine.

Many thanks for any help!!!

A:Solved: Cannot renew IP address/access wireless network

The "weird IP addresses...169.254.x.y" says that the PCs getting these are unable to contact the DHCP server (the router). Automatic Private IP Addressing APIPA is a feature of Windows-based operating systems and included in Windows 98, ME, 2000, and XP. The range of IP addresses (from through used for APIPA is reserved by the Internet Assigned Numbers Authority (IANA). Any IP addresses within this range are not used on the Internet.

The PC that does have internet connectivity is that a wired connection (you don't say). The two PCs that are getting the wierd IPs are both wireless connections. Yes?

For a wireless link check the following:

- SSID used on router is matched in the adaptor cards
- if using MAC filtering on the router to control access that correct MACs for the PCs are being used to allow that access
- if encryption is being used that the key(s) have been entered correctly on the router/wireless access point and all adaptor cards.

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

Good Day

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.

I have never had trouble connecting to internet before, let alone with an ethernet cable. Moved into a new place, my sister's laptop connects fine with a cat5. No wireless is set up/used.
I am very new to troubleshooting network issues.

When I plug my laptop in, I get "limited or no connectivity."
When I repair connection, "Windows could not finish repairing the problem b/c the following action cannot be completed: Renewing your IP address. For assistance, contact the person who manages your network."
Tried ipconfig renew/release.
Tried several things in command promt:
netsh winsock reset catalog
netsh int ipv4 reset reset.log THIS ONE DID NOT WORK, couldn't find the command, probably, as I found later in Local Area Connection Properties, because I do not have IPV4. Not sure if relevant.
netsh int ipv6 reset reset.log
netsh int ip reset reset.log
Rebooted, no change

TCP/IP properties: IP and DNS are set to Automatic
HELP please!!!!
