How could I add a user-defined path to the path
already set by Win 2000?
What are you needing this for? Because the answers may be different.
In general the User environment variable PATH is appended to the the
System (or Machine) env. var. PATH. So, to add a search path element
just append that to the User PATH string (including a ";" separator
as needed) via System Properties, Advanced, Environment variables.
This will be effective on your account's next logon.
commandprompt.admin answer might be to use the SETX.EXE Resource Kit
utility. Or reg.exe or merging a .REG file, (avoiding wiping out the
existing Path elements of course).
It may be that you just need to change the PATH for a particular
program which can be done in batch...
