I had this question after viewing Node(s) cannot reach a writable domain controller. Please check connectivity of these nodes to the domain controllers..

I am validating windows fail-over cluster. I am getting below errors. Can some help me out for this ?

Connectivity to a writable domain controller from node could not be determined because of this error: Could not get domain controller name from machine VMClient01

Connectivity to a writable domain controller from node  could not be determined because of this error: Could not get domain controller name from machine VMClient02

Hi All, I have 3 AWS VM's. VM01 is domain controler, VM02 and VM03 joined domain. I am able to ping VM's by IP , full name "" and AWS Private DNS butnot with "host" .  Can you please help me out for this?
I have one window user (Win10) that joined domain, so normally they will have no permission to make any changes on local computer, so i want to give permission on that domain user to be able only install any software on their computer but every strict permission keep as original, how to do that?
I have 20 or so computers in my office.

we have had a problem where when you first launch a browser, the first tab to come up takes upwards of 45 seconds to a minute to load.
concurrently opened tabs open up right away, but that first tab once you launch the browser (chrome) takes so long it's becoming unbearable.

my first instinct was maybe it's DNS, and i changed that to and, but the problem continues.

we use a cloud based application, so we are constantly using the network -- it's not arp resolution.

but the occasional times we have to look something up, we have to wait 30-45 seconds for the first browser tab to open.

this only happens on a few computers, the rest are ok


I've got a fairly simple set up - with an RDS server (.1.11) a DC/DNS at 1.14 and a client at a remote office connected via VPN at .3.2

The problem is that when the client attempts to reach the RDS server via name, it's attempting to reach it at its public IP address.   When I do an nslookup it's returning the private .1.11 IP address.
A client of mine wants the Direct Access role to be installed within a Server 2016 Hyper-V virtual machine.

I have already found instructions for setting up Direct Access but these guides don't include any instructions on how to set up the Hyper-V networking to support installing Direct Access within a Server 2016 Hyper-V virtual machine.

Please provide me with the instructions for installing Direct Access including setting up the Hyper-V virtual machine networking that is necessary for installing Direct Access within a Hyper-V virtual machine.

Direct Access will be installed on a server that has 4 physical RJ network ports.
When I run this statement, I get an error that says "%%G was unexpected at this time":
for /F "tokens=2 delims==" %%G in ('WMIC /NODE:"myserver" Service WHERE "Name = 'myservice'" GET State/value') do set CURSVCSTATE=%%G

But, when I run just the WMIC statement, it works fine:
WMIC /NODE:"myserver" Service WHERE "Name = 'myservice'" GET State/value

I'm pretty sure it has to do with the single quote terminating the WMIC command to early, but I can't figure out how to fix it!
How to combine two subnets?
AM  Volunteer IT for church.  Have one wired network, one server (W12 running DHCP) on 192.168.0 subnet mask with printer/copiers wired workstations connected thru POE switches to Zxyel Firewall/switch to Comcast.  File sharing and SQL databases on server.  Zyxel also splits off to VIOP phone system. Originally had some Dlink routers acting as Access points for wireless (worked, but campus not fully covered).

Independently, another volunteer got approval to purchase campus wide wireless.  Third party installed Ruckus wireless POE units (10, one a controller) on subnet 10.59.0 subnet mask running separate DHCP for wireless side (one workstation is also connected to this subnet).  All Dlink routers were removed. Supposedly inherent to the Ruckus system is health checking and repair/restoration of the Ruckus access points without human intervention.  I have no manuals or training on the Ruckus wireless system.

Needless to say, workstations (wired or wireless) on one subnet cannot see across the subnets. i.e. file explorer does not show machines on other subnet and visa versa.  Found that if I enabled WINS on the 10.59.0 systems, I could then address the server by manually entering servername i.e. \\servername\sharename.  Believe there are issues of getting to SQL databased from a wireless workstation as this week had to connect a wireless laptop via ethernet to setup an application using a SQL database.  There was a…
Hi All, client has synology nas shared folder mapped to w7,w8.1 & w10 pc’s.
After restart one of the  w10 & w8.1 pc’s mapped drive need it to sign in again with credit to enter again.

Also Map drive short cut on the desktop  still shows redcross after successful login too

I had similar issue last year with a w7 pc with synology too.

Anyone has similar issue why windows loose credit after restart?

Thank you

Dear Experts, I'm testing the RSAT tool on Win 10 client for Core-DC of WindowServer 2016; but when I clicked objects on "AD Users&Computers", it seem like the objects were missing some options and sometimes it did not respond.

Is it normal? If not, how can we enable or configure; so that they have same functions with that of a Domain controller with GUI?
I have a NAS server that I recently have lost the ability to access using the IP address. When an attempt to access I receive an Access Denied error. Below is what I have checked and the results.

  • I have verified that account credentials are correct.
  • I have verified that the account permissions are correct to access the share.
  • I am able to ping the device from any other device in the network.
  • I am able to access the SMB share using the Hostname and the FQDN with the same account credentials mention above but not the IP address.
  • I have verified that the IP address is not assigned to any other device on the network.
  • I have verified that the ARP table correctly associates the IP address to the correct MAC address. (However after a packet capture when the device attempts to authenticate with the SMB share it gets a response from a different MAC address which I can not locate anywhere on the network.)
  • I have verified that NTLM is not disabled on the device or in GPO.

I have reached out to the manufacturer (Panzura) and they said after reviewing the packet capture and all the items above they believe that it is a network issue. At this point, I have run out of ideas of what to do next. The manufacturer suggested changing the IP address, however, I would like to reserve that as a last resort.
We have total 7 scope configured in DHCP out of which 3 is showing blue exclamatory mark, when I click on display statistics for these 3 scopes all value is showing zero only. Event logs showing error messages like "DHCP client request from C42F909FAB66 was dropped since the applicable IP address ranges in scope/superscope VLAN40 are out of available IP addresses. This could be because of IP address ranges of a policy being out of available IP addresses." for all these 3 scopes only. However all these scopes are not more that 50% occupied.

DHCP lease is 10 hours for all scopes except scope for mobile user.

In DHCP properties DNS Tab
""Dynamically update DNS record only if requested by the DHCP clients"" is checked.
""Discard A and PTR records when lease is deleted"" is also checked.

Assign IP addresses dynamically to clients of: is DHCP

In DNS Scavenge stale resource records are set as No-refresh interval 3 days and Refresh interval 4 days for all the zones and scavenging Period is 1 Day.

I performed the reconciliation and restarted the DHCP services in both DC and is ADC. Also I checked by restarting our ADC as it was also showing the same thing but it also doesn't work however I have not cheeked  by restarting our DC yet.

Please suggest if anyone having the solution for this.
How can I give a user from another local Win10 computer folder permission to a shared folder?  These are individual PCs and not domain joined.
If I ping my desktop (Connected via LAN cable) from laptop (Connected via Wifi) with Static IPv4 it says Destination host unreachable both computer are windows 7 and connected to the same router (D-Link 2750 U).

Windows firewall is disabled on both machine.

How can I network this two machine one connected via UTP cable (LAN) and other with Wifi ?
This image will help you to understand the network I want to make.
We run a small network with less than 256 devices so we use static IP addressing (IP subnet
We recently expanded our equipment so I changed the subnet to on all existing servers, workstations, printers, switches, routers, etc to accommodate new workstations in the 192.168.1.? range.

Any workstation (new or old) that I change to the 192.168.1.* range has communications problems. Most notably drive mapping on logon and being accessed by remove viewing products like VNC. Each time I change a machine back to the 192.168.0.* range the problems go away.

Any direction on how to troubleshoot this issue would help !

Are you thinking about creating an Amazon Web Services account for your business? Not sure where to start? In this course you’ll get an overview of the history of AWS and take a tour of their user interface.

We have a Windows 2012 DNS server that is not behaving they way I had thought it would based on the MS documentation I found.
Round robin is disabled, and subnet prioritization is on.  
There are 2 local subnets (192.168.0.x/24 and 172.28.1.x/24), and one remote subnet of 172.28.150.x/24
DNS entries:

Name resolution works as expected (no round robin), and query return matches the IP of the local subnet it originated from.  For example:
DNS query for ServerA from host always returns
DNS query for ServerA from host always returns

But, DNS queries for ServerA from the 172.28.150.x network still return in a round-robin fashion, alternating between and
The 172.28.150.x network cannot route to the 192.168.0.x network, and so the query fails 50% of the time.  Or, I guess to be more accurate, the query doesn't fail, it just returns an IP that is not contactable by the requesting host on the 150.x network.  EDITED for clarity - I need the query from the 172.28.150.x network to return the address in the 127.28.1.x range.  There is not an option at the moment for a route to the 192.168.0.x network.

Based on the docs I found, I was expecting and hoping that the DNS server would return the "closest match" that it could find to the IP of the originating requester, starting with the left-most octet.  But this doesn't seem to work.  I have confirmed with …
It seems that the documentation about IPsec/IKE setup on an SRX to Azure s2s VPN is conflicting.  There are 3 pain points:

1.  Can IPsec/IKE be used on a policy-based VPN for Azure? It seems that Azure is clear about "no" but the suggested Azure config includes IPsec & IKE config
2.  Which IKE version is best for SRX to Azure - v1 or v2, when using Policy Based or Route-Based VPN? (see attachment)
3.  If a trust sec zone (internal interf.) and an unstrust sec. zone (exter. interf.) already exists, how can I add interfaces that are in one of those zones already to a new "Internal & Internet Zone" for the Azure VPN Tunnel as documentation suggests?  I receive an SRX error about adding interfaces to multiple zones prohibited and if using PB VPN there is no st0.x to that config and/or I don't understand how to utilize or place the traditional interface under the st0.x iface.

We're a WIndows network with a standard range of DHCP, DNS are on a server and I have a few wireless nodes on static IPs acting in bridge mode.

For quite a few clients, they will login, be assigned an IP, can access internal network utilities, but can't access the internet. The only way I can get them on is to assign them a static IP in an excluded range within their network settings. Primarily happens on the wireless networks but those get the most traffic and has happened wired in.

What could be going on that they'd be assigned an IP from DHCP, can access internal network utilities (email, shared drive, printers) but can't get an outside connect to the internet?
Adding 2016 server. Have it configured for RDP licensing. Cannot get existing gateway to connect to the licensing server.
NTP sync from Workgroup pc to a DC on a different network.
let me try to explain my situation and maybe someone can help.
we have 3 networks.   Office network, DMZ network, and Production network.
office network has a DC  lets name it ( office1), DMZ  network is a workgroup environment.   Virtual host and a virtual machine lets name it  (vm1).
Production network has a DC  lets call it ( prod1)

Currently "Office1"   is getting its time from external time servers.    Production DC  ( prod1)  is pointed to Office1  to sync the time.

I have to change the setup.    PROD1  has to sync to VM1  and  VM1  has to get its time from OFFICE1.

The virtual host that VM1 is running on is syncing already with OFFICE1.   and  VM1 is getting its time from the host.  
how do I configure PROD1 to sync  its time from VM1

thank you  for any help.
Hi all, looking for some assistance with a SQL cluster issue, would appreciate any assistance available.
xxxSQL07 is the name of the SQL cluster (windows cluster name xxxSQLCLU02) made up of two nodes; xxxsql03 and xxxsql04.
All works, able to connect using SQL studio using Windows Authentication (tried multiple accounts, including the service account that all SQL runs on on this domain).
The problem has presented itself as we've recently created a reporting server (xxxrpt02). The local publication has been configured linking to the only database on xxxSQL07 and wizard completed with no errors. From SQL studio on xxxRPT02, when trying to add a local subscription I receive the error message, "The target principle name is incorrect. Cannot generate SSPI context. (Microsoft SQL Server)". I've tested the reporting server by connecting to a local subscription on another SQL cluster which works, I also tested the faulty domain cluster from the other working reporting server and received the same error.
This error occurs whenever I try to connect SQL studio to this SQL cluster. I've also tried connecting to the name of the windows cluster but that didn't work.
In an attempt to fix this issue I took the xxxSQLCLU02 offline from failover manager and performed a repair in an attempt to get this connecting in to Active Directory correctly.
The SQL cluster name is pinging and the IP is resolving when pinging -a.

I've done some digging around and am erring toward this issue being…
