Exchange 2013 SP1 setup fails at prerequisite Analysis

Question

I installed a completely new server network with Hyper-v 2012R2
I installed two virtual 2012R2 servers: DC01 as the Domain Controller of "testdomain.local" and EX01 as the Exchange server.
EX01 is joined the domain "testdomain" from DC01
I log in on EX01 with an in AD created testdomain\exadmin account who is member of domain admins, enterprise admins, schema admins, administrators and group policy creator owners.
I have run the command Install-WindowsFeature AS-HTTP-Activation, Desktop-Experience,
NET-Framework-45-Features, RPC-over-HTTP-proxy, RSAT-Clustering, RSAT-Clustering-CmdInterface, RSAT-Clustering-Mgmt, RSAT-Clustering-PowerShell, Web-Mgmt-Console, WAS-Process-Model, Web-Asp-Net45, Web-Basic-Auth, Web-Client-Auth, Web-Digest-Auth, Web-Dir-Browsing,
Web-Dyn-Compression, Web-Http-Errors, Web-Http-Logging, Web-Http-Redirect, Web-Http-Tracing, Web-ISAPI-Ext, Web-ISAPI-Filter, Web-Lgcy-Mgmt-Console, Web-Metabase, Web-Mgmt-Console, Web-Mgmt-Service, Web-Net-Ext45, Web-Request-Monitor, Web-Server, Web-Stat-Compression,
Web-Static-Content, Web-Windows-Auth, Web-WMI, Windows-Identity-Foundation, Telnet-Client, RSAT-ADDS
on EX01
I have installed the Microsoft Unified Communications Managed API 4.0
Then I run the Exchange 2013 SP1 setup and the prerequisite check gives the following errors:
Error:

I can connect with the Active Directory Sites and Domains and other applets to the AD. So Why these errors???

Hi, thanks for the answer.
I restarted the server and did the "run as administrator": same result.
The first errormessage in the exchangesetup.log is:
[ERROR] Setup encountered a problem while validating the state of Active Directory: Active Directory server  is not available. Error message: Active directory response: The LDAP server is unavailable.  See the Exchange setup log for more information
on this error.
When I run dcdiag /s:DC01 from EX01 it passes all tests except:
DFSREvent "The RPC server is unavailable"
KccEvent "The RPC server is unavailable."
SystemLog  "The RPC server is unavailable."
Could these be of any influence?
Running dcdiag on DC01 passes all tests.
The only thing I changed after setting up DC01, was changing the fixed IP-adres from 192.168.25.3 to 192.168.25.2, but I ran ipconfig /flushdns and ipconfig /registerdns and dcdiag /fix afterwards.
The only roles installed on DC01 are AD DS (I tried installing exchange before and after adding the AD DS role), AD, DNS, DHCP and Fileservices
I don't know where to look anymore....
