I'm trying to add a server (Server B) as a child domain to an existing forest.  The server was originally setup as a domain controller to replace the on prem domain controller, but was later decided to make is a child of the forest since the NAS on site can communicate with multiple domains of the same forest. I have removed the ADDS role and demoted the server. The old domain controller has a functional level of Windows Server 2012 R2 and the domain is called XYZ.com. This server was originally setup on a 192.168.60.0/24 network. IT Management has setup the new server (Server B) on a 10.10.16.0/22 network and want to make it a child so that it's domain would be abc.xyz.com. Management has also added a 10.10.16.x IP address on XYZ. On XYZ, I have setup a new site in AD Sites and Services with the 10 subnet and have renamed the original Site for clarity and have set it up with it's 192 subnet. Both servers are manually configured with IP/Subnet Mask/Default Gateway/DNS. Both servers have 2 IPs, one on the 10 network and one on the 192 network. From Server B, I can ping xyz.com by IP but not by name. When I try by name, the replys come from the hosted website. Each network has it's own default gateway. I then go to server B and add the AD DS role and then proceed to Promote the server. I choose the option to "Add a new domain to an existing forest". The "Select domain type" is set to Child Domain. I click on the Select button next to parent domain name where it asks me for …

Hello experts,

I was manually pasting /over writing a new .dll for an application fix. I was mapping to the C$ drive of the workstations and pasting on the application folder in the program files a .dll fix.  Some workstations I had to stop the process in order to be able to overwrite it.

I will like to perhaps use active directory to do it.

The network is a windows network. What needs to be done is replace a dll file in all the workstation.

Thank you in advance for your help on this

Hi, I recently switched to W-10 and used ethernet connection to modem/router. I was surprised not having to provide a ssid and passcode to connect, and wary as I am seeing my status as  logged on to a 'local network', (my modem/router).  My question is, am I better protected using the wired connection, or should I unplug and connect thru wifi?

Hello Experts,
This customer of ours has a LAN with three mac OSX Yosemite,
procesor Intel 2.7 Ghz Core I5
8 Gb Ram 1600 Mhz DDR3

Inside each mac there is parallels with WIN 10 and our APP
Now our app works with MYSQL  and visual c# ,,,,
one of the MAC works as a server and the other two are stations consulting/updating the server,

All three macs are wireless and too slow
is it true.... if I switch to network cable instead of wifi,
 it may be faster at least something faster that we can notice ?

And what can I do to make these mac faster..
clearly they have not had any proper maintenance before...

but also is parallels also making it even much more slower??
not win 10 inside parallels shows a network speed of 1 GB is this reliable ?

Hi, just wanted to ask a bit of advice about changing IP addresses of a Server 2011 SBS network.  To cut a long story short I have to create some VPN connections between 2 networks that are on the same subnet and I need to change one network to be on a different subnet.

Both networks are on 192.168.101.x

2 questions really, if I change the second network to 192.168.102.x will that be enough to stop any VPN issues?

Secondly, the network I'm going to change consists of a Watchguard Firewall, Windows 2011 SBS Server and a network printer.  I have local physical access to the Firewall and Printer but not the server.  I'd just like a bit of advice on what device IP I should change first as I don't want to end up losing connection (will be doing this all over a remote connection).

Many thanks

Adam

All,

I have a project to use DHCP on Servers.  Has any one done this in their environment, any issues or risks?

Thanks!

It is a Server 2012 R2 Server. Somehow over the weekend the connection type changed from Domain to Private which in-turn changed the firewall settings. How do I get the network type back to Domain?

Hello Experts,
I am staying at a hotel for a month (work travel)
My laptop is connected to the local wifi.

I need to map a local folder in my laptop as m:
since many applications i have need to use that mapping in order to work

Now not being an expert, first I erased all sharings from COMPMGMT.MSC
fearing someone in the hotel may access my laptop....

then I shared the local folder and added a local user with full rights to the shared and security properpties...
But no I cannot access the folder when i go through NETWORK in win explorer..
and cannt either map the folder although i can see the folder name under its computer in the network...

What can I do so i can map this local folder and havng only my laptop access it ?
Regards

PD working with win10, toshiba laptop core i5

Similar to other posts we have to run Virtual Machines to accommodate Checkpoint VPN client just because all traffic passes through. We RDP to client jump boxes once connected. Forcibly setting route all to false doesn't change the outcome. Strangely, if we use the windows store checkpoint and win 10 Vpn it's ok. This is only with the client install, but the win store Vpn drops frequently and not desirable. Any help appreciated, doubtful client will change settings as we are 1 of many connecting.

I am running hyper-v on server 2012 R2.  Calling myself clever, I thought I would bridge two NICs on my host and then attach me Hyper-V switch to that.

Well, hyper-v doesn't see the network bridge.  It only sees the NICs in the host.

Does Hyper-V support connecting to a bridged NIC?

Thanks

I'm trying to deploy a Windows 10 image to a Dell Venue 10 Pro 5055 tablet, using an usb ethernet adapter. I'm can pxe boot to the MDT server, the tablet gets an IP and it goes all the way where it asks for the user's credentials when I try to authenticate the user I get the error that says *Invalid credentials: The network path was not found. But in mean time I'm able to authenticate the same user when I deploy the image to a regular PC without any problem. I have tried to inject all the drivers for the tablet on the image and also the drivers for the ethernet adapter but still no luck. Also when I hit f8 I can ping my server and  ipconfig shows that the tablet is getting an IP. Any help will be very much appreciated.

We have been asked to connect a 200Mbps fibre connection (expandable to 1Gb) to 10 independent business units in a small business park. The fibre provider will put a Cisco 1921 router on the end. They have no interest in managing the ongoing connections to the individual business units. That's down to us. Someone recommended a Cisco SG500 switch to add to this to satisfy the requirements:

1. control of bandwidth to each unit so they each get what they have asked for (and paid for) and no more
2. separate public IP assigned to each business unit (one each)
3. each unit can only access internet and not each other's networks

This is a little outside my day-to-day networking experience so rather than fumble my way forward, any pointers, issues to watch out for would be much appreciated.

Thanks,  Andy.

Hello,

we are facing vmware migration problem in vCenter.
we try vmware migration from one datastore to another datastore but its showing warning for destination host not  compatible.

Please find warning:

vMotion interface 'vss:Management Network' on the "Destination" host "102.0.0.0" does not have the recommended capacity (full duplex/1000 Mbps) to properly support vMotion

i have changed Network Adapter -> Duplex actual Speed -> 100 Full Duplex to 1000 Full Duplex but after the server rebooted its set 100 Full Duplex (Original Speed)

please advice,we  can go ahead and start the migration regardless of that warning.

I setup OpenVPN Access Server using the public AMI available on Amazon about a year ago.

Part of this includes the ability for Users to sign-in to an OpenVPN Connect webpage. On this page the Users can download the a client to run on their local systems.

The client the Users download is OpenVPN Connect Client 2.1.1.102.

The latest version is 2.4.2 that is available on the OpenVPN Downloads page.

How can I replace the older client on my Server with the newer client so that Users are getting the latest version?

Thanks in advance for your assistance.

We have a VPN tunnel that gives us access to an network shared folder on a remote server.  I have mapped that drive on our domain file server.  I was curious if there is a way that a domain client could remotely access the mapped drive on that particular server without having to add firewall rules for the vpn so it can directly map the drive?

Server A  
z:\ = \\1.1.1.1\FileShare

Client A = Gain access to the files on the Z: mapped server drive without mapping the drive locally iteself?  

A little bit unorthodox, but working with the remote ends Network Team is a bit cumbersome.

Hi Experts,

I am looking for a network monitoring tool to deploy in our network.

I am doing some research and I have the following two options  (I have not tired them yet).

PRTG and NetCrunch.

Any recommendations on the above two network monitoring tools?  Have you used any of the two tools in your network and do you like what is offered ?

Thanks

Hi,

      We have a customer that someone put there internal domain the same as there external website domain. So there windows domian is for example abc.co.uk but there website is also abc.co.uk

I have put in a www a record on DNS pointing to the IP that i get back from pinging abc.co.uk.

However the issue is now if i try and navigate to the website in the internal network i get www.www.abc.co.uk come back.

And by the way it does work outside of the network :).

Thanks

We currently have a Dell Sonic Firewall that is our firewall as well as our company router.  This is our main router for all of our sites in the company.  We have 16.  We implemented through our EMR (Electronic Medical Records) software an upload to a billing company.  They in turn configure and print bills and send them out to our customers.  This has worked fine for over two years.  When this was implemented, we were not required to make any firewall changes at all.

A week ago, the user doing this procedure received an error that the file could not be uploaded.  She called the EMR company, who in their effort to troubleshoot the problem, changed the upload method from ftp to sftp.  She then tried to upload and she got an additional error that port 22 was unable to send.  Seeing that error, the EMR said that the problem has to do with our firewall.  I spoke with the billing company who tried to do a trace route to our external IP.  They were unsuccessful, but I was able to do a trace route to them.  The only caveat is that the user can do this procedure from home with no problem.

I am willing to make firewall changes if necessary, I just don't know what they would be or why it is necessary now, if no one has made any changes other than the upload method from ftp to sftp.

Please help.  I am desperate.

Hi all,

I am not a fan of Powerline devices, but sometimes I just have no other option then to use these device to get my signel to te area where it is needed. So therefor I would like to know which brand is best and what specifications to consider when making a certain choice.

I know it is best to use it on the same power group to get the best results. Therefor I often place an extra power outlet so that I work in the same power group. But I am wondering:

- Does brand make a difference
- Does speed make a difference in distance or stability (perhaps a 200MB goes further than a 1000MB)
- Do extension cords with adapters (i.e. a phone charger) have influence on speed and stability

And so on, so to sum up: how to get the best results with Powerline.

Thank you,
