Lync Client Can't Download Address List and other problems

Question

We're currently in the process of testing for a production Lync Server 2010 deployment and we're run into some problems. I've been digging around on the Internet and the Technet forums but can't find a solution to this problem.
Whenever someone logs in with the Lync Client, they are immediately presented with prompts for user credentials. No credentials work. When you cancel out, you can still chat, but there is an error that says the Address Book can't be downloaded. I've confirmed
that the SSL certificate works, I've made sure the Kerberos Account is configured properly, I've reinstalled the Web Components, and I've tried numerous other solutions I've found for this issue. Nothing seems to fix the problem. When I try to run test-csaddressbookservice
in the Management Shell, I get the following:
cmdlet Test-CsAddressBookService at command pipeline position 1
Supply values for the following parameters:

Answer 1

My situation was somewhat different but running Test-CsAddressBookService would fail with error:
'The remote server returned an error: (404) Not Found.'
All clients were unable to retrieve contact unless the full sip address was entered.
Environment.
Server: Lync2013 STD
Client: Lync2010
Did the following:
Checked replication under the Topology tab in CSCP- mine had a green check.
Reinstalled .net 4.5 via add/remove programs
Registed .net by running the following from an elevated cmd (run from .net folder) : aspnet_regiss.exe -I
uninstalled Lync webcomponents from add/remove programs
From Lync install media- reinstalled webcomponents.msi (browse to \Setup\amd64\Setup)
Checked IIS>Application Pool and ensured all ASP.NET and Lync components are set to v4.0 of the .Net Framework Version
Launched the Lync setup and reran step 2: Stetup or Remove Lync Server Components.
Reran Test-CsAddressBookService: 
successful
Tested Lync client: Successful
