How to make iMac friends with AD?

Question

Active Directory

There is an iMac with OS X 10.10.5 and there is a Windows 2012R2 server, AD, DFS are deployed.
iMac got into AD, logged in under an AD account, connected it to a network folder, set everything up, everything is in order, everything works (except that I had to install Parallels and win xp for bank clients there).
But from time to time it falls off from AD, so you have to reboot and beat the tambourine to make everything work again, it happens rarely, but it is extremely painful, since the iMac is the director and owner.
I sinned on WiFi, connected via Ethernet, but it still did not help.
How to deal with this situation?

Answer 1

Install iAD)))
In general, look at the logs on the CD, the computer account in AD, apparently something is happening with the secure channel, the password of the computer account is not updated ...

Answer 2

I think the problem is with the domain time. See if the domain and mac times are more than five minutes apart. Maybe there is some regularity . I have 30 poppies in the domain and there are no such problems.

Answer 3

Hello, what is meant by "falls off the HELL"?
Indeed, conflicts with time stamps in the computer account in AD are possible, it may make sense to register ntp on the poppy - a domain controller.
