I have successfully deployed a Lync 2010 topology and can sign in successfully via the client, but after a few seconds I am prompted with a popup:
 
Credentials are required
Type your user name and password to connect to the certificate service


Some users get this messages, another not, what can I do it?

1.) First at all, make sure your Lync is up to date (including the client)
http://technet.microsoft.com/en-us/lync/gg131945

2.) Here is a tool to test lync connectivity
http://www.insideocs.com/Tools/MOCLogin.htm

3.) You can CRTL-rihgt mouse on the Lync client tray icon to see connection information

4.) Check how users log in, the Sip Account is like an email address, but user name can be a kerperbos (like email) or NeBios Domain\username format.

5.) There may be a tracing log file in C;\users\%username%\tracing

OK, check if the clients can resolve the certificate, what is installed on the LYNC. The client should have the Root certificate in the local cert store to validate the cert.

If dialin is configured, you can test it by https://dialin.yoursipdomain.tld. The browser should not throw a cert error (assumed dialin works from internal clients and was added to the Lync cert).
