A guess that he is running one of the RedHat linux versions
that run ntpd as user "ntp". A number of these had an
install error that installed the directory /etc/ntp as belonging
to root. I suppose "chown ntp.ntp /etc/ntp" might work.
Later versions from ntp moved the drift file to /var/lib/ntp/
might be a better place for a writeable status file
as opposed to /etc/ntp; the latter is then left for true
"configuration"
As stated, if the original poster could provide some additional
information, this might enable a more exact response.
If this is a linux system, also helpful would be the output from
ls -ld /etc/ntp
and the output from
ps -ef | grep ntp
although the latter is somewhat sensitive to the version of "ps"
installed.

Hello gang,
I am running into real weird problem:
here is the line from /etc/ntp.conf
# Drift file. Put this in a directory which the daemon can write to.
driftfile /etc/ntp/drift
After I run ntpd (ntpd -n -g -U ntp -N high -p /var/run/ntpd.pid -l
/var/log/active/syslog/ntpd.log)
after some time I see following lines in my log file:

and in my /etc/ntp directory I have no drift file created.
I am confused, shouldnt drift file be created ? When is it created ?
What is it used for ?
What happens if the the file is not there ?

What operating system are you running? What version? What version of
ntpd are you running? What account are you using to run ntpd? What
are the permissions on /etc?
Basically, nptd is telling you that it does not have the necessary
access rights to create the drift file. If ntpd is not running as root,
and apparently it is not, you need to alter the permissions on /etc to
allow ntpd to write to it or you need to run ntpd as root.
Ntpd can run without a drift file but every restart will be a cold
start. If it were able to create the file it would write the current
frequency correction to the file once per hour. When ntpd restarts it
will read the file and use the value found there as the initial estimate
to the frequency correction. This speeds up synchronization.
