Next: Kernel Stack InPage Error when data is written to Server

Hi,

the wonderous world of Microsoft technology never fails to amaze me. It such
a pleasure working with Windows 2003!

Today my trouble is with w32tm service. Most of the clients on my network
seems to synchronize with the time server with much trouble - they all get
warnings but thats probably how its supposed to work I figure?

However, a few machines have some serious issues. Once or twice a day the
user connected to these clietns are thrown out. I have tracked this issue
down and I strongly suspect that it has to do with the kerberos login service
and the windows time server failing to synchronize. In other words, users
comes so far off the server time they are thrown out. (And this is a domain
server so all clients are constantly interacting with the server).

Anyway this is the setup:

Windows 2003 Domain Server with AD working soley as a fileserver and
administrative point for sysadmins.

Clients consist soley of 30 machines with XP Pro SP2.

In the event log of my server I get this error:

"
Error Event 29
The time provider NtpClient is configured to acquire time from one or more
time sources, however none of the sources are currently accessible. No
attempt to contact a source will be made for 480 minutes. NtpClient has no
source of accurate time.
"
Some test commands on the server and their result:
c:\>w32tm /dumpreg gives:

Like a charm!

Now, this gives time out errors. Client cant seem to communicate with server?

Returns 0x800705B4. Something is clearly wrong!


Here is the LOOONG list of registry settings on how I have w32time set up on
the server:

Thats about all the data I could dig up I think.

I have set up the time server according to the documents listed on Microsoft
technet so dont bother posting a link to it please. The clients connect to
the domain server, so there cant be a firewall issues - since the clients
themselves doesnt contact the external time source.

I would really like to know what is going on! I would appreciate any ideas
greatly!

Thanks!

P.S. I have read about a hotfix that supposed might fix time synch issues.
Should I implement it? And can anyone send me a like to where I can download
it? I disdain the idea of having to call up Ms techsupport as suggested just
because they are to lazy to put it up for download *groan*.
