Symptoms

Environment library fields overwritten, unable to connect to server with K2 Studio.
 

Diagnoses

Some environment library fields had their values overwritten. Fortunately, a deployment had not yet occurred and we were able to reset these values based on the current string table. Had that not been possible, running a repair would have been an alternative, or building the connection strings by hand.
 

Resolution

We used the settings off of my VM along with the values in the string table to properly set environment library fields back to original values. We then ran a repair on the K2 client tools in order to update K2 studio's connection string values, which allowed us to connect again.
