If your TecDoc uses a client-server database (like Firebird or InterBase), the database engine must be running.
Win + R, type services.msc, press Enter.Firebird Server, InterBase Guardian, or TecDoc DB Service.Modern TecDoc systems often run on a local database server (like MySQL or Transbase). If the database service stops or the password changes, the config file cannot complete the connection handshake.
The Fix:
Services.msc in Windows.MySQL, Transbase, or TecAlliance.[Database] section.Server=localhost (or 127.0.0.1)Port=3306 (or whatever port is assigned)User= and Password=tecdom.old).Tecdoc data is massive (often exceeding 50GB to 100GB+). It is usually delivered via an initial full data dump (DVD/USB/HDD) followed by incremental updates via an FTP server.
D:\Tecdoc\Data\ but the drive letter has changed, the external hard drive is disconnected, or the FTP path has been updated by Tecdoc.[Source] or [FilePath] directory.
