Goran,
Have you tried increasing the Timeout on that device? I'd double it,
for now...
I suspect some unknown load (Exchange??) on the server is causing a
random delay is answering the DNS query. Setting a longer timeout may
cause the device to be seen as up more often . In other words, the
longer timeout may help, but may not make the problem go away, just
won't show up as often in WUG.
If the longer timeout helps, then I'd look more carefully at that
server for resource issues...

It is a Windows 2000 server, SP 4 running Exchange 2000 SP3 for about
20
users. Not really high load at all.

Is the DNS server a Windows server 200x server under very high query
load with a large cache?

Subject: [WhatsUp Forum] DNS services continuously going down and up
Hi All and Happy New Year to everyone,
I am monitoring a number of my client's servers via a VPN tunnel and
there is this one server that is setup just like all the others but it
keeps reporting that the DNS services goes down. Then on the next poll
(or so) the services comes back to life. Life is fine for 30 to 90
minutes when the DNS goes down again. I have the alarm trigger set to
4.
I have checked the server and there are no entries in the event log
for
problems.
Any thoughts on what could be causing the DNS to fail and then
reappear?
Thanx
