Lync 2010 client - problem verifying the certificate from the server
I am having issues signing on to my Lync account from my PC only. I was able to sign in from a member server in my domain.
However, when I sign on using my PC i get an error "cannot sign in to lycn - there was a problem verifying the certificate from the server."
I cleared my Lync cache and even remove a cert from the "Personal" container in the certmgr which I believe was suppose to be for my Lync.
I flushed dns, rebooted a few times and followed a few MS KB's and still no luck.
I believe the problem in fact is related to a cert.
How can I go about requesting a new cert? I haven't touched the CA world in sometime..
thx

I was thinking there is now a problem with the cert on my PC? I thought there needs to be a cert installed on the Lync client(pc) in order for me to auth ?
You can create a backup of your profile and then import it after to restore your profile items.
If you logged into another machine you have then tested that another profile corrected the issue.
Are you using an internal CA or is your cert from a 3rd party SSL provider? If it is from and internal CA then it might be the cert on your machine but that should be easy to correct. Just export the cert from a working machine and import it into yours.

it is an internal CA ..
i am not sure exactly where to find it. well. maybe its the correct one.. so i connected to a server. logged in using my lync account..
open cert mgr and navigate to personal - certificates -
in here i had saw the communicator ( lync i suppose) cert which i exported and then imported on my client pc.
Same error. however, I am not sure if the export/import is transpiring correctly. There is a private key associated however, I am not sure this is been imported

it seems like whoever created the certificate did not mark the private key as exportable.
So is my only choice to create a new one from scratch? how would I do this?
I would like to avoid messing with my profile seeing that it is 90GB

You do not want to re-issue certs for Lync as you will need to re-publish the enitre topology. What is so hard about re-creating your profile?
- rename your profile to profilename.old
- login with your account, let it create a new profile
- test to ensure you can connect to Lync
- once this is verified copy your my docs/favs/desktop items to your new profile
Thats it

i will give it a shot
ASKER
prior to renaming it to .old i created a local account on my PC ( not a domain account)
I logged in and tried to connect to lync and received the same message. However, i am not sure if this has to do with the fact that I am not using an AD account or simply because the problem continues
Would reinstalling Lync be worth a shot?

i complete reinstalled the application. Still no luck.
I noticed that I removed the cert from the personal store - the one i imported from a server but that didn't work because the private key is not exportable.
Anyhow, when I try connect, a new cert isn't generated in the personal store.
For some reason i don't think my profile will be the fix.

Couple of possibilities to try.
1.
Is the time and date correct on your PC? Is it sync'd with the domain?2.
You said this only happens when from your PC. So I assume your account works fine from another PC. What happens when someone else logs into your PC? Do they get the cert error?3.
Can you try removing your PC from the domain, rebooting, and adding your PC back to the domain?4.
Do you have any static entries in your HOSTS file?ASKER
Has this been tested on another machine?

i just fixed the issue. by desktop team pointed me to the correct CA Certs and I imported them in to my trusted root store.
all works fine now

thanks will.
Yea it looks like I was missing the certs. However, I am not sure why it worked for some months before this error message. I will leave that as a mystery.
