time sync problem; useless error msg



An error occurred while WIndows was synchronizing with time.windows.com. The time sample was rejected because: The peer's stratum is less than the host's stratum

What is this supposed to mean??

The problem is with those 2 servers, time.windows.com and time.nist.gov

If you edit the registry and add another time server it works fine.
I just did it.

Add a new string value
Name it 3
add the name of a time server as the data
use this list http://www.eecis.udel.edu/~mills/ntp/clock2a.html

Information on editing the registry

Always be careful when editing the registry, you can stuff up your PC if you
change things you don't understand

I had a similar problem to Mr Hencken's. Same error message. I thank you
for the information & will attempt to follow it up.

Nevertheless, it would help to know what that error message means. Is there
really something wrong at NIST? But more to the point, what's a stratum?

I clicked on "time synchronization" to find out what a stratum was & how
to make the peer's stratum greater than or equal to the host's stratum,
assuming that was what I had to do. I found no mention of the word
"stratum" anywhere in the material displayed. (Since there is no keystroke
for doing a search with this facility, I can't be sure, but I looked
carefully & more than once.) I then did a search for "stratum" in the
general help index & found 3 instances in the knowledge base. One of them
was an article on setting time in Win 2000 (not for WinXP); again a search
of the article yielded no mention of "stratum." I looked at another of the
Knowledge Base articles & also drew a blank. A stratum is usually a layer
of something, but it's hard to relate this to the problem at hand.

So, my question is maybe a little more fundamental than Mr Hencken's: (a)
How can I find out what a "stratum" is? I couldn't understand that article
in the Knowledge Base. Oh, & by the way, (3) is there any way I can search
a displayed page in the Help & Support system for a word, similar to the way
you can search a Web page with ^F?

Hi Kenrick

Yes, I did. I just got a message saying there was an internal error. :-(


Thanks very much, Mark! I'll give it a try. Pray for me that I don't bollix up the Registry. (I'll back up, just to be sure!



i think the problem has something to do with dst time changing...happened to
me too...looked for another ntp server and it worked well.

Stratum just means level

The distance a host running the xntpd time daemon is from an external source
of Coordinated Universal Time (UTC). A stratum 1 server has direct access to
an external source of UTC, such as a radio clock synchronized to a standard
time signal broadcast. In general, a stratum n server is n-1 network hops
away from a stratum 1 server. For example, a stratum 4 server is 3 hops away
from a stratum 1 server. Also, a stratum n server is at a higher stratum
than a stratum n-1 server. For example, a stratum 3 server is at a higher
stratum than a stratum 2 server, and at a lower stratum than a stratum 4
server. See also ``time daemon''.
Stratum 1 time servers are at the top of the heap, then stratum 2 and so on.
