A hotfix is a program file that installs one or more files to correct a problem. An Exchange 2000 Server hotfix program file is named Qnnnnnn.exe, where nnnnnn is the number that is assigned to the hotfix.
Hotfixes released after Exchange 2000 Server Service Pack 3 (SP3) support the following Setup switches:
/? -- Display the list of installation switches.
/u -- Unattended mode (same as /m).
/m -- Unattended mode (same as /u).
/f -- Force other programs to quit when the computer shuts down.
/n -- Do not back up files for removal.
/o -- Overwrite OEM files without prompting.
/z -- Do not restart when installation is complete.
/q -- Quiet mode (no user interaction) and unattended mode (same as /u or /m).
/l -- List installed hotfixes.
/x -- Extract the files without running Setup.
For example, the following command line installs the update without any user intervention and does not force the computer to restart:
filename /q /z
All hotfixes are listed in the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates\Exchange Server 2000\Service Pack Number\Content ID Number
