Utility maintaining the INF.SYS file. The INF.SYS file holds the users' database. In case of problem in INF.SYS file, goto the SYSTEM directory and run MAINTINF followed by a number of months. The records of users not connected within this number of months will be deleted and these users will be asked as for a new connection. The number 0 will not delete any record and only check the INF.SYS file.
