Dear Experts
We have main office with Windows AD as DNS and DHCP server, we have following requirement
1.      Branch office is connected over MPLS network to main office, branch office IP subnet is and main office network is 109.0/24 both the networks can talk to each other, we would like to join the branch office systems to the main office Windows AD domain. Please suggest how and where to add this IP subnet in the windows AD so that branch office different IP subnet gets resolved with main office Windows AD, please help with steps on “HOW TO”
2.      Few home users connect to the office network using Cisco Anyconnect client VPN software with the IP pool series. please suggest where in windows AD to configure this IP pool so that this gets resolved via windows AD DNS.
Thanks in advance.
I have 3 cisco routers with gateway to gateway vpns setup. Location 2 can ping the local domain (mydomain.local which resides at Main Location1) and everything works just fine. Users can connect to the domain perfectly.

Location 3 cannot ping mydomain.local or the netbios name of the server at MainLocation1. I can ping the ip address of the server at MainLocation1.

MainLocation 1 (Where the server resides)
Location 2 (satellite office)
Location 3 (satellite office).

On the workstation at Location 3 I manually assigned dns 1 to the server's ip.

Other details: All of the routers are the same. Any help I can get would be much appreciated!
Cannot use Windows Explorer in Windows 10 Pro. Version 1903 from work group PC to see a folder share on Windows Active Directory computer.

We have some test computers that are on their own network and we must configure the host file to use DNS hostnames those computers can recognize and access the A.D. names for folder sharing purposes.  The folder share access/process works from Windows 10 Pro. computers with version 1803; but if those computers are upgraded to Windows 10 Pro. version 1903 they can no longer access the folder share from the A.D. computers.  The Windows 10 Pro. computers that have version 1903 are workgroup PC's.

Earlier we would use the UNC (Universal Naming Convention, start-Run - \\PCNAmeHere) and then one is prompted to enter the Active Directory username/password.  Then they have access to the folder share.  When the PC is upgraded to version 1903 they are no longer prompted to enter a username/password.

The PC can still ping the hostname that is indicated in the host file and its IP address; but, explorer cannot see the shared folder from Active Directory.  Instead an erro comes up stating "Windows Cannot Access \\Servername_Here\Shared_FolderHEre".  error code 0x80070035.

My question is what can I do to get the folder shares accessible to the Windows 10 Pro. computers that have version 1903?  Other already existing Windows 10 PC's that are still working have an earlier version .. 1709, 1803.
Its been a while since I shared a folder in a Workgroup let alone a Windows 10 workgroup. We have a 2019server that is part of the workgroup and its where we want to share one folder from.  Does anyone have a good step by step reference on how to setup a user from another computer to access a resource from another computer?
Why can I not see all the computers on my domain?
I am having problems sharing a folder from my Windows 2007 R2 server,

If the folder to be shared is (target folder) is in the root of a local drive then simply selecting, right-clicking and selecting 'Share With...' allows me to create a share. This can be confrmed by a) I can see the share from another machine b) on the server's  [Device Manager - System Tools - Shared Folders - Shares] the new share is listed.

If the target folder is not in the root of the drive then repeating the above actions does not create a share - verified by the two methods above.

Can someone advise the correct way to create a sub-folder share ? I need this becuase I am using the share on another location but that folder can't' be moved on the home server.
How to create a shared mapped drive within a domain
DNS and DHCP Interaction

Recently we had to replace old  computers with new ones but we kept the same hostname , the new computers get different IP address than the old ones from DHCP.

Example :

Old ComputerA  replaced and named  the same ComputerA
Old ComputerA IP address:
New ComputerA IP address:

What I have noticed after replacement:
If I login locally to New ComputerA, and run Ipconfig, I will see  which is correct.
If Remotely I ping by hostname the ComputerA,  I get with Destination Host Unreachable. [you can see it looks for old IP address]
if Remotely I ping Reverse lookup : Ping -a , it will Reply properly and shows ComputerA  with IP

So the problem seems to be the DNS A record does not get update quickly,  I said Quickly because after sometime, if I go and ping by hostname ,ie : Ping ComputerA, I get a proper Reply with

My question is I do not understand why Reverse Ping [Ping -a <IP address>] will Reply quickly and Ping Hostname did not Reply until later time....

Any clarification will be very much appreciated.

Thank you
I have a Peplink Balance One Router at work and intend to connect 2, or more computers from the same LAN to no avail. Only one connections seems possible. Is this by design?
On the router I use L2TP/IPsec and Windows 10 built in VPN client.
i stop ip6 in windows but for ping a hostname in windows 10 i have return   ::1:
how to change it?
it should return ip address
Our Airtame wireless HDMI application searches for available Airtame devices on the network and shows them on the opening screen. We have multiple HDMI devices in the same building but on a different network. These devices can be accessed from the default network by typing in the IP address in the Airtame app. My question is: - Is there a way to use DNS or some other method to make these devices automatically discoverable as if they were on the same network?
Dear Wizards, our users need to modify the Date/Time settings on domain-joined PCs. Can we do that? please suggest.
I need to set up a trunk on two HP Procurve switches, not sure yet on model but I have been testing on a couple of 2920-24G J9727A

I have set up Trunk Trk1 across ports 1 and 2, and then tagged Trk1 for both my vlans, i have then repeated this on the second switch. As i havent set up trunks before, i did this via the GUI (switch firmware 16.09.0003)

Everything seems to be working ok, spanning tree is enabled and both ports are still active.

Am i done?, looking on the manual, there are two methods, Trunk group operation using LACP and Trunk group operation using the "trunk" option.

Current switches already have VLAN1 being used for data, vlan50 for voice and vlan3 for management.

If i need to change it to LACP, can the use of vlans stay the same or does vlan1 need to go?

show trunk  displays ports 1 and 2 in Trunk Trk1
show trunk trk1   returns  module not present for port or invalid port : trk1  
Not sure if that means something is wrong?

Hello Experts,

I am trying to access an IP Video camera on my private network from the Internet.

1. I have verified the camera can be accessed via a web page from the private LAN.
2. My IP camera is currently using port 80
3. I set up port forwarding in my DSL modem to access the IP Camera IP via Port 80.
4. I can verify the port is open using (If I remove the port forward in my modem, the route from fails)

When I try to access the IP camera from the internet by typing http//"MyPublicIP:80" the the browser times out.

So I believe I have port 80 open but I cannot access the IP camera on my local LAN from the Internet.

Does anyone know what may be going on here?
I have a network with the range 10.4.240.x to 10.4.243.x. I should be able to reach / ping any device on the network from any address. For the most part, I can. The servers /printers and other resources are all on the 10.4.240.x subnet. From any other subnet I can ping the servers and printers and access them fine. What I can't ping or access is the routers gateway on It does not respond to a ping request and isn't accessible. Any computer on anything other than 10.4.240.x does not have internet access because the device can not see the gateway. I have no idea why this one ip address isn't responding.

I'd appreciate any ideas to try to resolve this problem.


Good morning-

I'm running into an issue I've never seen before and am seeking some assistance.

Windows Server 2012 R2 AD domain with 30 users and 2 domain controllers: dc1 and dc2

File server /w 2 file shares: R and T drive

After a Windows Update users are no longer able to access these file shares. They are receiving the following error:
"the target account name is incorrect"

Sometimes you can access the share drive but it will time out and go back to the error mentioned above.

However, users can browse to the file share via explorer just fine using the UNC: \\dc1\share. Computers can also ping both dc's by DNS just fine as well. I have rebooted both dc's along with the file server in question. Additionally I have disjoined and rejoined the file server from the domain no avail.

Can someone please point me in the right direction as to how to proceed?  Thank you!

In RD Web Access, how can I publish application (Windows 2016 Terminal server)?
Is there a way to set IP address, mask, gateway and DNS at a CMD prompt? Going through the GUI
is a pain. Thanks!
Picking your brain about password policy.

I was checking a few password management best practices and some of them discourage the "forcing users to change the password" policy, they advise that users change their passwords if they suspect it's been compromised. I still believe that forcing users to change their password coupled with other password policies can really make a password more secure. I was wondering if anyone out there  gave up on forcing users to change the password and what was the reason for that..

Thanks as always...
I think this is a simple question for folks with more experience than I, with shared workstation files in a domain:
I'm trying to suitably limit access to files on workstations while still providing for file shares on them.
The "current user" logged onto the machine should have Modify, Read & execute, List folder contents, Read and Write
A single domain group needs have Read & Execute, List folder contents and Read but doesn't need Modify nor Write.

How would you set this up so that wider access is blocked BUT not limiting normal / accepted administrative maintenance, etc.
(Yes, I know that even doing this is a bit unusual - so please humor me).

Do I have this much right?:
In a peer-to-peer network, shares with Everyone permissions (Guest inactive) are fairly well limited to local users with accounts on that workstation.
If nothing is changed, except to join a domain, shares with Everyone permissions (Guest inactive) let in all of the Authenticated Users on the network.
So, something needs to be done with those Everyone permissions - at least!

Hi, I'm using the Quarantine feature from Watchguard and this creates a Quarantine website users can log onto. But the problem is that it's an intranet server and as such doesn't have an 'official' SSL certificate. I tried to create a self-signed one etc but I keep on failing ... could someone please give me step-by-step instructions on how to create a self-signed certificate and attach it to that website so that the browsers won't throw their security warnings anymore? Thanks!
We have a Windows domain with a 2003 Server domain controller with Windows 10 Enterprise computers.  I plan on taking a computer off the domain and connecting as a test to Azure Active Directory.  My goal is to retire the local domain server and have all our computers completely on Azure Active Directory.  The one problem is there is a QuickBooks file that is shared on the local domain controller for the accounting department.   If I am connected to the Azure directory, can I still connect to the domain controller to share this one resource using the Windows 10 machine?
