Re: Effect on users when rebooting a DC

Tech-Archive recommends: Fix windows errors by optimizing your registry



Hello IainM,

Normally they will not notice it, if it is only authenticating users and does nothing other. I also reboot my DC's during working hours if needed.

If there was a few thousand users who had authenticated to the DC
being reboot, but had network drives connected to a different file and
print server, then I take it that they wouldn't notice anything?

Many thanks for your replies d|lano and Meinolf - Exchange was one of
my main concerns.

Hello D|an-0,

Exchange will use one DC for authentication, check ion exchange
system manager the recipients update service, which DC is used.
Otherwise they have problems to connect to exchange, if this dc is
down.

One DC (and this is the one that sparked off this question) has
all the FSMO roles except Forest Wide Naming Master. All DCs are
GCs and DNS servers, but the ones I'm concerned with do not have
any file & print or other applications running on them. I have 19
DCs for this domain.

Thanks,

When we reboot a DC during working hours (emergency patch

will have on users, particularly users who have already
authenticated against the DC being rebooted.

Has anyone got any ideas? We use Exchange, and AD provides LDAP
services for various other applications, e.g. proxy
authentiation for internet access, SAP.

Thanks,

Is this the only DC on your network? If so, users may loose
access to shares on the network if they haven't authenticated
with the DC prior to accessing the share. If The DC is also
your file server, all user may looses access to files unless you
have off line files enabled. Need more insight as to what other
roles the DC has before giving more input.

If there are no applications or files on the DC, I think it will
be transparent to the users.

A remedy to the issue with Exchange being unavailable is to enable
"cache mode" on your Outlook clients. This way, when you reboot the
server, Outlook will notify your users that they are working off
line and data will transmit when it is back on line.
