lopar's questions

I have an AD network with 3 DC. After a migration with changing PDC emulator we have a problem where SYSVOL and NETLOGON shares are not created.

We have found community manual, temporary workaround by modifying registry value HKLM\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters SysVolReady 0 => 1.

After that we encountered a replication error, where dfsrreplicatedfolderinfo state become 2 (Initial Sync) on newly added DC. So we moved to Microsoft Manual, but unable to run step DFSRDIAG POLLAD, because Windows Server Core 2022 does not have DFSRDIAG or server feature RSAT-DFS-Mgmt-Con. Get-WindowsFeature RSAT-DFS* returns nothing.

I cannot find information about RSAT-DFS-Mgmt-Con starting from early 2020s. Can someone please tell us?

I use upstream and proxy for load balancing.

[[email protected] ~]# cat /etc/nginx/nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

events {
    worker_connections 1024;
}

http {
    upstream sites {
        server 192.168.1.237:8080;
        server 192.168.1.240:8080;
    }
    server {
        listen       80 default_server;
        listen       [::]:80 default_server;

        server_name  _;
        root         /usr/share/nginx/html;
        include /etc/nginx/default.d/*.conf;

        location / {
            proxy_pass http://sites;
        }
    }
}

When I open 192.168.1.135 in browser, it tells me, that «Site is temporarily unavailable».

All pings from 192.168.1.135 are working:

When I point my browser to http://192.168.1.237:8080 or http://192.168.1.240:8080 — they succesfully open.

What went wrong? Thank you.

Is there any way to patch Hyper-V Server 2012 to Hyper-V Server 2012 R2? Or I need to download & install new version instead with manual VM migration?

I tried to google it, but found answers only about Windows Server 2012 with Hyper-V component.

Thanx.
