The Uninstall
Okay, I've stepped into it.
I started a post yesterday about how to back out of an install when you've got it wrong. What I did was select Kerberos Authentication for the Central Adminstration website and once the Configuration Wizard completed, I couldn't open CA and I didn't want to take the time to configure the SPNs for my service accounts just now so I wanted to do a "post-config" uninstall.
So I just deleted the databases, the web site and the app pool and thought I'd just run the wizard again.
Not such a great idea.
The wizard remembered the old farm, but, without the configuration database available, it couldn't "unprovision" it. The WSS entry in Programs and Features wouldn't uninsall either; It offerred a Remove or a Repair option but neither would run to comletion; they would both start and then just quit and go away.
Eventually, I ran Setup.exe again and it offered a Repair option. Once it finished, I ran the wizard again and it gave me a dialog box that said "Error connecting to existing configuraiton database" and I said "really?" My only option was to cancel and when I did, I was able to run it a second time and it was happy to allow me to create a new farm.
So, what we've learned is the Proper "Post-Config" Uninstall Procedure.
- Run the Configuration Wizard and, on the second page, select Disconnect from this server farm and click Yes on the warning dialog. This will delete the IIS web site and the application pool.
- Then, run the uninstall from the Control Panel's Features and Programs application and click Yes on the warning dialog. This will take a reboot.
- Then, if you really want to get rid of it all, go to the database server and delete the Config and Admin Content databases.
