I'm trying to install Lync server 2010 but i'm stuck for a while now with the "Active Directory Preparation" part of the Lync server 2010 installation. The "Prepare Schema" fails with the following error: "Step 1: Prepare Schema Run once per deployment. Extends the schema for Lync Server. Not Available: Failure occurred while attempting to check the schema state. Please ensure Active Directory is reachable."
The situation: 1 server with Windows Server 2003 (x86), which is the only Domain Controller (DC) 1 server with Windows Server 2008 R2 (x64) where Lync should be installed.
First I have found that the DFL/FFL were not correct:
On the DC (server2003) I have changed the Domain Functional Level to Windows Server 2003 and also the Forest Functional Level to Windows Server 2003. If I check these settings on the Server2008 with Active Directory Domains and Trusts, I see indeed that the DFL and FFL are being set to Windows Server 2003. (Windows Server 2003 is the minimum required for Lync server 2010)
I tried the Lync AD Preparation again but still got the same message: https://skydrive.live.com/#cid=CB15F1A932B364BE&id=CB15F1A932B364BE%211742
I'm logged in on the Server2008 and Server2003 with the domain administrator account. If I check "Active Directory Users and Computers" and go to the directory Users and watch the properties from the Administrator User then it is also a Member of:
- Domain Admins
- Domain Users
- Enterprise Admins
- Schema Admins
- Group Policy Creator Owners
The firewall on the server2008 is turned off, still nog working
So now my question is: what should I do to make the Lync setup (Active Directory Preparation) work? (I would appreciate clear step-by-step suggestions to check.)
Thanks in advance.
Now I've extended AD successfully on the 2003 DC, using this link: http://blogs.pointbridge.com/Blogs/sloan_jason/Pages/Post.aspx?_ID=2
but when I check the Active Directory Preparation again on the Lync install, it still gives me the same error as in the screenshot I've provided.
Update 2: I found out that there is a log on "C:\Users\\AppData\Local\Temp\ with this:
Get-CSDomainState > Get Domain State
Error: An error occurred: "Microsoft.Rtc.Management.ADConnect.NoSuitableServerFoundException" "No suitable domain controller was found in domain "OurDomain.LOCAL". Errors:\r\n"OurDCserver.OurDomain.LOCAL5.2 (3790)5.2 (3790) Service Pack1OurDCserver.OurDomain.LOCAL5.2 (3790)5.2 (3790)Service Pack 1""
I thought Lync could be installed with a Windows Server 2003 (according to the documentation on technet) and it doesn't require a SP. :s
