When a user logs on a metaframe server, Usrlogon.cmd will be started. It's an alternative loginscript for a terminal server. Usrlogon will first start UsrLogn1.cmd. This script is used for situations where you do not have or need a rootdrive mapping (chkroot in application compat scripts). Next it will run usrlogn2. Here you can script special mappings and checks that you do not want to happen in the central logon script because you do not want to apply this to every domain user. Only users loging on on this server will get this script. This way you can script automatic profile creation (outlook), map special printers, map special drives etc. If you enter CHANGE USER /INSTALL the moment a user (admin) logs on the server will be in installation mode. Normally, when installation continues after reboot, you do not have the time to open a command prompt and type in the sequence manually.
