Solaris NTP Client to Windows 2000 NTP Server

[Hackett, Peter]

Are there known issues with the NTP server available with Windows 2000? I
have several Solaris clients pointing to a Win2000 NTP master server who's
supposesed to be syncing to 3+ external time sources, but time seem erratic
on the Sun boxes, and the network switches pointing to it.
 
Comments / experiences appreciated on this.
 
Thanks,
Pete
