Can I install multiple security hotfixes on my Windows NT 4.0 servers without having to reboot the servers after every installation?
Microsoft's qchain.exe tool lets you install multiple updates or hotfixes in a chain without rebooting between installations. Qchain also evaluates your DLLs, drivers, and executables to ensure that only the most recent versions are installed on your NT 4.0 systems. For more information about Qchain, see the Microsoft article "How to Install Multiple Windows Updates or Hotfixes with Only One Reboot" (http://support.microsoft.com/?kbid= 296861). You can download the tool from the Microsoft Download Center (http://www.microsoft.com/dowloads/details.aspx?familyid=a85c9cfa-e84c- 4723-9 c28-f66859060f5d&displaylang =en).
