Most of the updates ScanMail does not require a reboot but I have run
into situation where I did have to reboot the server because in the
middle of the update, something was hanging. Restarting the services
for all ScanMail processes did not work. Trying to restart the
Exchange System Attd service did not work either. Users were not
able to get emails as a result of the hang....thats where a necessity
for a reboot.

OK. But that should be a rarity if it happens at all. Your scanmail updates
should happen automatically (I have all my Trend stuff set to download
updates hourly) - make sure you're using the latest supported version. And
if you're not talking about pattern files, but engines/etc., that stuff
needs to be scheduled ahead of time.

Not meaning to jump all over you here, just trying to help.

& ScanMail updates requirement

Scanmail does not require a reboot for its updates. And Windows
updates should be done after hours or on weekends. Sorry, I'm not
sympathetic to that one.

and people are still working late
because they need Internet access to watch webcasts for focus group
etc and that's why I need to set up a secondary DNS server. They
might not need email access at the time but anytime there is no
internet access its like the roof had collapsed. I don't want to
wait until they are done with their work until 9 pm and reboot the
SBS server. I don't want to reboot the server either while at home
for problems that might arise sometime.

Sure. But you must know that you manage networks, sometimes after
hours work is necessary. You just need to schedule it beforehand -
and surely your company can tell all users "Two weeks from Friday
the network will be unavailable after 6PM." Talk to your management
about this. If you have to stay a bit late every month or two, well,
that's IT work - come into the office a bit later that day. Even if
you set up another DC, this is important.

Thank you for pointing out about PDC/BDC in AD as peers. I never
knew about this chemistry.

No prob.

You thru me off when you mention making "If you set up your
secondary DC properly, with
DNS, and make it a global catalog server, you can then add this
server's IP address to your clients' IP config as a secondary DNS
server (via DHCP, one hopes)."

I thought the primary DC is supposed to be the Master of all.

FSMO roles, yes. I think Merv gave you some good links....

Why
would I have to make BDC as the Global Catalog server.

Because all DCs should be GCs - there is no downside to doing so, and
other things may not work if you *don't*.

To my
understand, GC server is an index mechanism that keeps info of every
objects on AD network correct. When you have SBS install that is
the master of all is not that true?

No, not entirely. See above.

If not, how do I make the BDC as the
GC server as you have mentioned and as the backup DNS server.

BTW,
BDC is a windows 2000 server, do you think SBS 2003 likes sharing
its DNS information with this version of OS?

You may have some group policy issues, but overall, no, it shouldn't
be a problem.

Thanks,
Helen

Note that there's no such thing as a PDC/BDC in Active Directory.
All DCs are peers. And yes, I would expect plenty of crying phone
calls if you're rebooting your SBS box in the middle of the work
day, and not just because of DNS issues - that shouldn't be
happening at all. If you're having major problems on the SBS box
which require regular reboots, you should address those
immediately. If you post in here with the details I am sure
someone can help you out.
which is
where DNS is host. So do i need to set a secondary DNS on the BDC
or can I install it on another member server?

If you have an additional DC already, it should be set up with
AD-integrated DNS (this is normally done when you set it up but you
can do it later). Do not set up DNS on a member server, and do not
set up a secondary DNS zone. AD relies heavily on a properly
working DNS structure and if you mess this up your domain will be in
bad
shape. Be careful!

Can you also answer my original questions as well.

Sure - but you hadn't explained your question or your situation
well enough for me to do that before. If you set up your secondary
DC properly, with DNS, and make it a global catalog server, you can
then add this server's IP address to your clients' IP config as a
secondary DNS server (via DHCP, one hopes).



Thank you,
Hhelen

There is a Backup DC on the network

Good morning,

I want to set up a second DNS server on SBS network again but I
can't remember what I have to watch out for on SBS network. Its
is going to be a secondary DNS server on the 2nd server
correct? Do i enter the ip address of the primary DNS server in
the property tab of the 2nd server?
Thanks,
Helen

You should only do this if you're adding an additional DC &
AD-integrated DNS server for redunancy.

If that's not the case, you should probably explain what it is
you're trying to accomplish.....
