HI, I've already tried to sync.time solaris client to the Windows Time server, but it's always failed. but when I sync. with another solaris timer server it's succeed. What should I do..?
Thanks

I assume that you use the Network Time Protocol (NTP, see https://www.ntp.org/) in order to query the MS Windows server for its time. Unless you do not have a NTP service on the Windows machine this won't work. AFAIK the Windows Time Service can only be queried by Windows clients. I don't recall having seen a tool that can do this under Linux or Solaris.=20
Provided your network is "big enough" I'd set up a local time server and have other servers query this machine by means of NTP.
Best, René.

In fact, I don't think that this is even possible - unless you come up with a way to "reverse" the whole messed-up system that Wind0ws Time Service uses. This is one of those places where Unix and Wind0ws are fundamentally incompatible: in Unix, UTC is the basis of the time system and is modified by local settings; in Wind0ws, the local time is the basis... and it results in incredibly ugly hacks (e.g., see recent discussion about changing file time stamps during the DST change in the RISKS Digest.)

Yep. Wind0ws can use NTP easily enough; Unix just can't use their version. Pretty typical.

Um... doesn't Samba do that?
net time setshould set the system time to that of a windows (or Samba

I quote:
[...] unless you come up with a way to "reverse" the whole messed-up system that Wind0ws Time Service uses.I forgot that Samba does just that. Although it would be interesting to test if it is "properly" broken in the same exact way that Wind0ws is.
