I have an issue with a SQL 2008 R2 Standard default instance (running on Server 2008 R2 Std.) which appears to be missing parts of its installation.
The SQL Server Browser and SQL VSS writer services are not listed in the Services MMC snap-in, I also do not see the sqlbrowser exe file in the Shared directory.
When I attempt to repair the instance, the repair Wizard detects the instance but only believes that the Full Text Engine is installed. When I attempt to add a feature to the instance, the wizard does not detect the DB engine as installed - it allows me to select that option for new install and proceed through the installation wizard - it asks for auth type., new sa user password, service accounts, etc. as if nothing is installed. I stop short of starting the "install" fearing that this will cause conflicts and issues with the currently functioning databases. I know for certain that the Database engine is installed because there are active databases running at present and the associated applications are functioning normally. I am also able to log into SQL Mgmt Studio and manage the DB instance - nothing there looks off.
I recently removed a SQL 2008 (not sure if it was R2) Express instance (I chose to leave Shared components in tact) and the timing lines up with when I noticed the aforementioned services missing (Backups stopped working so I started to investigate). The uninstall appeared to work properly but I still see the Reporting Services and Full-text Filter daemon for the Express instance in the Services MMC. Add/Remove programs gives no indication of this instance existing.
Thanks in advance for your assistance.
