We have 800xA system SV 6.0 with seperate redundant Domain server, AS and CS.
I want to know whether operator workplace is will work properly if both domain servers are down.
We tested in our system and found that for installer account, operator workplace is functioning with some delay in opening and navigation. But for operator login, the operator workplace itself is not opening. Is it the normal behaviour?
It will work "for a while". It's not possible to say how long.
Whenever 800xA tries to start a service, the service must contact the domain controller to autheticate the account that runs the service. If the domain controller can't be contacted, then the account uses cached login details **IF** they are available and not expired. The same is true for user accounts.
The 800xA system will continue to operate for some pretty much random amount of time after the domain controllers are lost. If you are lucky this may be several days or more if nothing serious is disturbed. Or it may not be that long.
