Symptoms

When Remote Authentication Dial-In User Service (RADIUS) uses an ODBC data source for validation data, it cannot re-establish a connection to the ODBC data source if the connection is broken (database crash, database maintenance, network storm, hardware problems, electrical outages).

Cause

No retry logic was implemented for ODBC, so the service fails to start if the database is unavailable, and fails to reconnect if the server is unreachable for any reason.

Resolution

Windows NT Server or Workstation 4.0

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
