Karma fails to launch IE on Team City build

Question

Karma is failing to launch IE when running under Team City. I can log onto the sever and run the tests from the command line, but IE always fails from Team City:

Answer 1

The issue was that IE had never been run under the service account we use for the Team City agent. It was getting stuck on the IE options dialog that opens when the browser is first run. Once I ran IE and accepted the default settings it runs on the build server:
