Many of us would have fall under such situation when you are trying to install Lync 2013 Edge serer role again on any previous failed installation. So what happened. In the previous installation, Lync 2013 setup created RTCdatabase instance which may failed to rewrite while you again run the setup.
We have been seen this issue in one of the EDGE server located in Lync LAB and fixed it by remove old RTC instances and reran setup again
1: Below screen show that Lync 2013 edge setup is failed and not able apply SQL script for the feature RTCDatabaSstore.
2: We tried to connect SQL instance of Edge server from one of the SQL backed console using “SQL Management Studio” and deleted them one by one.
3: I understand that in production environment you can not connect edge server from internal SQL server as its sit in perimeter network. So you can install one dummy SQL server in same Subnet where Edge server is localized and remove the RTC local database.
4: Run the setup again from lync 2013 deployment wizard which would go smoothly.
I hope it could help someone have faced such issue 🙂 🙂 !!!!
