Windows 10: Our AD server cannot replicate with corporate AD server

Dear Support Team, Our Active Directory AD server is currently experiencing replication issues with the corporate AD server. Upon reviewing the logs, I noticed an issue that I believe requires support assistance. I've already attempted to ping and perform port queries TCP and UDP to the Corporate AD, and everything seems to be working fine from our end. However, it appears that from the corporate side, they can ping our server but are unable to perform a port query. I already open all the port from my AD server firewall but still not workPlease assist me in check this issueThe File Replica

AD Replication Issue

Hello,

We have an issue with AD replication at work. We have 3 ADs, 2 running Windows Server 2012 R2 and 1 with WS 2019.

The 2 servers with WS2012R2 can replicate between them but not with the 3rd one. But the server with WS2019 can replicate to the other 2.

What am i missing here.

Thanks

 

Upgrade Step for Windows AD Server to Windows Server 2019

Hi all,

I need your help as my situation below,

Primary server:

Windows 2008 R2 Standard (Master)

AD CS

AD DS

DNS

Secondary Server:

Windows 2012 R2 Standard

AD CS

AD DS

DNS

Replication AD only from Primary to Secondary server.

We have bought Windows Server 2019 Standard for two and we plan to upgrade both server,

I have found lots of step to upgrade AD server for easy ways by adding the bootable Windows iso media and run adprep /forestprep.

But I am worry If some thing else messup the configuration and AD itself.

My Plan,

1: Upgrade windows 2012 to Windows 2019

2: After all done, I will start upgrade Windows 2008 R2 to Windows 2012 R2

3. An then start to Upgrade to Windows 2019

Question : Any step or prerequisite before i start upgrading ? (for example, AD might not working during installation or etc)

Thanks
