An error occurred while validating the available time updating k9copy

Right after fixing that issue, Mac started updating the OS to Mojave. I tried installing the OS 3 times but every time, it got stuck before 7-9 minutes remaining to finish the installation.

But in between, I received “An Error Occurred Validating the installer data. After receiving the error message, I started searching on the internet for various solutions.

When I click the resolve button I get an error "An unknown error occurred while validating the server". make sure the DC is not behind the firewall , or the windows firewall is not blocking...

I have read that for some it is fixed by enabling IPv6 and I have done that and also I have tried disabling my firewall but I still get this error. @Syed In this particular site I have only one DCGC and if you are asking over-all in all our different AD sites we have about 40 DCGC's It is running AD-Integrated DNS and yes when I open the command prompt and say nslookup this could be for many reasons; make sure you have A and NS record for the DC try to run dcdiag /v on this dc and check if there is any error?

I already posted a tutorial about Macbook Updates not showing mac OS Mojave and its solution.

If you are a Macbook enthusiastic, you definitely have heard about its latest major OS release named mac OS Mojave.

It is the fifteenth major release of mac OS from Apple for Macintosh computers.

I have an issue with one of my Windows 2008 R2 DC's and that when I go under DNS on the server and under Forward Lookup Zones and then under Name Servers.
