Lync 2010 continuous prompts for Office 2010 users

Lync 2010 is deployed internally. All the Office 2007 users are fine, but users who have Office 2010 installed are getting 4 prompts for credentials after the sign-in to Lync. The prompts say "Credentials are required. Type your user name and password to connect to.. W, X, Y, or Z. W= "the certificate service". X= "for retrieving response groups". Y="the corporate address book". Z=" retieving location information"
Providing the credentials in all formats does not help (Domain\username, UPN,..etc). The users have to cancel out of each prompt. Lync works fine after cancelling, but users cannot search for corporate contacts.
February Lync  cumulative update installed for the users, but the prompts are still there. Tracing is not showing anything relevant.
Any ideas, experts?

Thanks -

It looke like I may have figured it out. It appears to be a Kerberos issue that was only being picked up by machines with Office 2010 on them. I redid the Kerberos configuration and so fat the tests are good.

Sorry. I thought I closed this question. To resolve the issue, I removed the Lync Kerberos account through the Shell, enabled SCConfig, then I re-added the account. After that process, Office 2010 users no longer got prompted.  The issue has been resolved for a while now.
