from our windows 2008 server. The older switches without the sntp authentication feature are
able to receive ntp time updates.
When I make a wireshark trace on our windows 2008 server I see the NTP request, but the server does not respond.
Is this a known bug ?

Re: Windows 2008 as ntp server
K15.xx is made from K.14.41 and there was a bug with sntp and windows servern, which was fixed later, i guess with K.14.55 or something.. but i guess the fix did't make it to K.15.xx

SolutionYou may need to configure audtitting to log more detailed events.
Although not preferred, try broadcast mode to see if this behaves differently.
The switch may require the timeserver itself to be in sync with a master timeserver.
MS reports about ntp in windows server 2008
http://technet.microsoft.com/en-us/library/cc773263(WS.10).aspx :
Important
The W32Time service is not a full-featured NTP solution that meets time-sensitive application needs and is not supported by Microsoft as such. For more information, see Microsoft Knowledge Base article 939322, Support boundary to configure the Windows Time service for high-accuracy environments (http://go.microsoft.com/fwlink/?LinkID=179459).

Re: Windows 2008 as ntp server
Here I receive the following warning.
Warning: this request expects an authenticated response, but did not provide the client ID. Sounds like we're responding to a server response, which is incorrect behavior. However, this can also be caused by other applications broadcasting NTP packets, using an unrecognized authentication mechanism.
Look likes I am hitting the following bug:
SNTP Authentication (PR_0000048588) ├в With SNTP authentication disabled, the
switch sends extra, unnecessary authentication information in the SNTP request packet.

Re: Windows 2008 as ntp server
Should be fixed in K.15.03, which is available now. Not yet released on the web, but can be obtained via support.
Cheers,
Michael
