Sync problem in a multilevel network
Hi,
I've been having trouble trying to get a multilevel network synchronized with w32time.
This is the structure of my network:
- level A: central server, source of the time (win 2008 server)
- level B: 2 servers in cluster, they sync with level A server (win 2008 server)
- level C: servers that sync with level B (win 2008 servers)
- level D: clients that sync with level C (win xp embedded)
I wanted to set a polling time in level B servers (for test purposes) of few seconds, so I set "SpecialPollInterval" to 10 (seconds) and "Maxpollinterval" to 7 (2^7 seconds, right?). The thing is, they don't sync after that interval, and I didn't manage to understand what is the polling time. I have to force them with a resync, or restart them.
After I forced this sync, level C syncs, but level D is not able to sync. I get the following error: "The time sample was rejected because packet contains unreasonable root delay or root dispersion values. This may be cause by poor network conditions"
I'm don't think is a network problem, since if I force it by clicking on UPDATE NOW, it syncs.
So the questions are:
- why level b doesn't sync within the interval set in specialpollinterval?
- why I have that behavior in level D?
Thanks a lot for your help, I'm going crazy :)
