If you don't have access to K2 Workspace for some reason, this simple query will give you the current environment settings directly from a K2 database:
SELECT E.EnvironmentName,
F.FieldName, V.FieldValue
FROM
EnvironmentSettings.._FieldValue V
JOIN
EnvironmentSettings.._Environment E ON E.EnvironmentID = V.EnvironmentID
JOIN EnvironmentSettings.._Field
F ON V.FieldID = F.FieldID
ORDER BY E.EnvironmentName
