I'm trying to map a network drive using item level targeting based on a security group. When I map the drive based on security group it doesn't show up on client computers. If I map the drive based on a single user it works. Why is this happening
I have a question.
Currently, this OS is Windows Server 2019. The volume configuration is Raid-5. The two servers are connected by a heartbeat network Both nodes were mirrored using WinDRBD. Both nodes have the same configuration. I left unformatted G: and set D: to be visible to the primary node.
my resource are below
include "global_common.conf";
resource "foo" {
protocol A;
net {
use-rle no;
}
on node1 {
address XXX.XXX.XXX.XXX:7600;
node-id 1;
volume 1 {
disk "G:";
device minor 1;
meta-disk internal;
}
}
on node2 {
address XXX.XXX.XXX.XXX:7600;
node-id 2;
volume 1 {
disk "G:";
device minor 1;
meta-disk internal;
}
}
}
Both nodes worked normally. The tests were completed by switching roles. ( primary → secondary / secondary → primary )
However, the problem occurred after booting.
After booting, the status appears as below. (both nodes)
foo role:Secondary
volume:1 disk:Diskless
node2 connection:StandAlone
I thought and searched a lot, but couldn't find an answer.
There were a few things I was suspicious about.
I wonder if it's because I tried before the G: letter was assigned to the drive. If my thinking is correct, is there a workaround?
If it is now my opinion, but the above problem continues to occur, what is the cause?
Once it was solved in the following way. But I want to find the cause and fix it accurately.
drbdadm down foo
drbdadm up foo
Thanks in advance for your help.
I have the network structure as the image below.
Server1 has 2 NIC cards that links to the 168.172.x.x network and 192.168.1.x.
I want my ClientMachine1, 168.172.1.15, to connect to a port in 192.168.1.92's program. The program is on a specific TCP port. Is it possible to do it with Windows Firewall or some program? Is having a router, the only option? I have limited knowledge on networking, please I need your advise.
I tried using netsh command, but it doesn't seems to work. I am using a program (via a specific port) in ClientMachine1 to connect to the Server2 to get the data.
The below command is the netsh command I used
netsh interface portproxy add v4tov4 listenport=1234 connectport=1234 connectaddress=192.168.1.92 protocol=tcp
Server1 is a domain controller, Server2 and ClientMachine1 joins the domain as Server1
we have a real odd issue. Multiple users have noticed that their computers are unable to access various web and file based services at specific times 4 hours apart.
I've noticed the "disconnection" at 12.02pm myself and trying to access internal web based systems gives me a 404 page not found error. Others have noticed file shares becoming unavailable.
The outage lasts approximately 2 minutes each time.
We're running a 2 node Server 2019 hyper-v cluster with an infortrend SSD SAN backend and the services I describe are distributed across both nodes.
I've checked the host servers even logs, I checked the network switch logs and even some client event logs and nothing seems to correspond (or be anywhere near) to the time that the outage happens.
In tests we've run multiple Pings to hosts and VM's from endpoints to see if there is a network interruption but there isn't so much as a fluctuation in the MS response times. I realise Ping is a bit of a sledgehammer but given the duration of the outage I would expect to see something reflected but again nothing.
I'm at a complete loss so would be grateful for literally anything that might point me in the right direction.
thanks in advance,
Paul.
I have 2 member servers on my domain that are getting an event 8018 which looks like this:
Log Name: System Source: Microsoft-Windows-DNS-Client Date: 4/21/2016 10:57:23 AM Event ID: 8018 Task Category: (1028) Level: Warning Keywords: User: NETWORK SERVICE Computer: Computer.domain.local Description: The system failed to register host (A or AAAA) resource records (RRs) for network adapter with settings: Adapter Name : {58413179-8931-4FFB-9764-DD65696FCC74} Host Name : ComputerName Primary Domain Suffix : domain.local DNS server list : x.x.x.x, x.x.x.x Sent update to server : IP Address(es) : x.x.x.x
The reason the system could not register these RRs was because the DNS server contacted refused the update request. The reasons for this might be (a) you are not allowed to update the specified DNS domain name, or (b) because the DNS server authoritative for this name does not support the DNS dynamic update protocol.
To register the DNS host (A or AAAA) resource records using the specific DNS domain name and IP addresses for this adapter, contact your DNS server or network systems administrator.
These 2 servers are joined to my domain and are in Active Directory. When I go to do an ipconfig /registerdns on these 2 servers I get this error. I went into my DNS server on my Domain Controller and set the DNS updates to Secure and Nonsecure. When I got back to the ipconfig /registerdns and then check the event log again it gives me an event 8012 saying that it couldn't update the PTR record but checking the DNS it shows the A record updated.
If these 2 servers are joined to the domain why are they not sending secure DNS updates for A records?
