Abstract
A Max Sessions Server (MSS) automatically detects hardware and communications failures. Upon detection, counters are adjusted accordingly to maintain an accurate count of users or groups of users on a system. A database of unique identifiers for each connection is maintained, where the unique identifier is a concatenation of a Network Access Server (NAS) and the connection's incoming NAS node number. If a user requests permission to log into the system, the MSS first checks the database to determine if the unique identifier is already logged in. If so, then a hardware or communications failure has occurred and the MSS must make the appropriate adjustments to the database and counter.
