Installing Lync Server 2013

When installing Lync Server 2013 on Server 2012 I recommend this

And if you install on server 2008 R2 I recommendthis blog for the prerequisites.

REMEMBER to install with the right user from the start. And this user NEEDS to be domain admin.
I tried to install with a local admin and got help from a domain admin on steps that required this. This gave some problems on the installation.

First problem

The Shared directory was created by local adm and the domain adm hadn’t any rights. So I put the Domain Admins in the RTCUniversalServerAdmins.

Second problem

Some how I couldn’t reach SQLServer instance though FQDN? Normally this wouldn’t be a problem, but as the Lync Server setup used FQDN I needed it..
Some googling told me, that I needed to activate Name Pipes on the server configuration.

Third problem

The third problem was Error: Prerequisite installation failed: SqlInstanceLyncLocal  I checked the SQL Server and found that the Domain Adm wasn’t admin in the SQL Server..
I tried again but the same error?!?!
After some Googliung I found that the installation should have a RFCLocal, and found that it had the same problem with missing rights..

Fourth problem

The fourth problem gave more problems.. It seemed like the same problem as above.
Error: Prerequisite installation failed: SqlInstanceLyncLocal
Installation result: -2068578302

Googling didn’t help as the result code wasn’t findable.
Then I dived into the log and looked at what was being executed.
Executing external command: C:\ProgramData\Microsoft\Lync Server\Deployment\cache\5.0.8308.0\SQLEXPR_x64.exe /QUIET /IACCEPTSQLSERVERLICENSETERMS /HIDECONSOLE /ACTION=Install /FEATURES=SQLEngine,Tools /INSTANCENAME=LYNCLOCAL /TCPENABLED=1 /SQLSVCACCOUNT="NT AUTHORITY\NetworkService" /SQLSYSADMINACCOUNTS="Builtin\Administrators" /BROWSERSVCSTARTUPTYPE="Automatic" /AGTSVCACCOUNT="NT AUTHORITY\NetworkService" /SQLSVCSTARTUPTYPE=Automatic
Actually Lync should have yet another SQL-instance - LYNCLocal. Icouldn’t reach it at apparently it couldn’t be created. So finally I looked into the Services and found the instance was stopped. I tried to start it but without luck.
Actually the service didn’t depend on the SQLServer and to fix it i uninstalled the instance and ran the installation again and.. Woosh it worked.
