[Samba] Turning one DC down for a day

[Stefan G. Weichinger]

I have an FAQ, I assume I know the answer but want to be sure before I 
run into issues:

At one customer they get new network cabling and switching this week.

This means that the connection between the 2 floors will have to be 
offline as well for some time, while the upper floor should stay active.

I have 2 samba DCs there and plan to move one of them to the upper floor 
for that time ... and the other DC in the ground floor will be turned 
off while work is done.

My question: is there any problem in taking one DC off for a day and 
then reconnect (= turn it on again) it to the domain?

I don't talk of joining, simply turning off and on with some hours of 
downtime.

There won't be any AD-changes from my side, no new users or so, just 
some PCs authenticating.

I assume that this won't do any harm to my AD ;-) ... but I prefer to 
ask in advance.

Thanks for any feedback here.

btw: samba-4.12.10-Debian on the DCs there
