There is a need to configure a laptop at a location where the wifi it will be connecting to is not at the location where it's being setup.
Once the laptop arrives at the new location it needs to connect to wifi.
Is there a way to  pre-configure a wireless SSID and password to access WIFI prior to sending it out to the new location?
if yes how can this be done?
We are having a strange issue when we try to add a network printer to a Windows 10 1903 machine. We are adding a shared printer from a 2008 R2 print server, it does not seem to matter what print driver is on the share. When we double click on it it does add it since you can print from Word and Notepad, but it does not show up in "Devices and Printers" or "Printers & Scanners"

We noticed this on our customized image, so we tried hand loading a 1903 machine without any other software and still the same issue. We also hand loaded a 1709 desktop and on there, everything worked as is should. It seems the problem is only occurring on 1903

Has anyone else ran into this?

Not sure how to exactly describe the situation but I will try to describe it as best as I can. Our goal is to have our domain computers connected to our network wired and wireless simultaneously. We also want to set up a GPO to have our domain computers connect to the wireless network automatically.

Before setting up a GPO for this, the our computers had always been connected to the wireless network and the wired network simultaneously. It wasn't until after we created a GPO to have the wireless network connect domain computers automatically, that the network can only be wireless or wired.

If we unplug the computer from the wired connection, it would take about 1-3 seconds to automatically connect to the wireless network. If we plug the wired connection back in, it disconnects from the wireless network. We don't want our users to disconnect from the wired network and wait 1-3 seconds to reconnect to the wireless network.

How can we have two connections "connected" simultaneously?
For some reason my Bitlocker Network Unlock server is not responding to client unlock requests. The DHCP servers are on the domain controllers The WDS/Bitlocker server is its own VM.  I have tried multiple certificates from Internal CA and self signed they get propagated down to the clients and are set up correctly on the WDS server but I cant get any client to unlock.  The clients report EVENT ID 24684 Bootmgr failed to obtain the BitLocker volume master key from the network key protector: failed to send request and 24645 Bootmgr failed to obtain the BitLocker volume master key from the network key protector.  I can see through wireshark that the client sends a request to DHCP and to the WDS server which it receives but never responds.  The client request is IPV6 which I can see on the WDS server after the IPV6 request goes unanswered the client sends out a IPV4 request which the server does not receive.  Any ideas?

Dear Experts
We have to deploy mail server on-premise for which we have thinking to go for microsoft exchange server.
my network consists
•      server virtualization -vmware infrastructure.
•      two ISP’s for high availability and windows AD for user management.  
•      CISCO ASA with FMC  
The user base we are looking for email server is too small that is 25 users. please suggest the email security solution that we should be considering  please recommend few best products for the email security. thanks in advance.
I have a situation where we have two law firms sharing office space. Both have their own ISP provider, phone system and network
However, they want to share a new leased copier so that the good print, scan via SMB and make copies.
-      the copier has only one network port and a USB port.
-      Confirmed that this copier does not support an external wireless adapter which I was hoping it did so I could allow one of the network to communicate to the wireless adapter using their IP subnet. That is not an option
-      I do not want to add a second NIC to every PC under one of the law firm’s network

I was thinking about purchasing a USB to network converter that I could attach to the copier/printer and onto one of the networks. Not sure this is a feasible workaround

Would appreciate any feedback

I have 4 Cisco 350 network switches on a small closed network.
I am running quite a lot of multicast network audio and video.
I understand I need to enable IGMP, but am confused about what I need to enable on the 'master' switch, and what I need to enable on the other 3.

Can anyone help?

We have a Skype account for our company.

We sign in with our company email address to access our Skype account on our Windows 10 Pro PC.

For people to get in contact with us, they usually request a Skype ID.

Our Skype ID displays as something like the following: live:" "_(numbers)

Other companies have their Skype Name/ ID displayed without the "live:" part like "walmart" for example.

We would like to change our Skype ID/Name to something better as it does not look professional.

We are aware we can change the display name for the account.

How do we change the Skype Name/ID for our Skype account?

We are having a BSOD in W10 64b with this code and ndis.sys. I think that the problem is with the network adapter. I Updated windows and drivers from the official website and still happening. Also I checked if the disk is damaged and it's fine.
Any recommendation?
Thank you

We have some HP and Dell PC (Win 7 & Win10). Some of our staff will have SSL VPN connected to our office for remote access their PC by remote desktop.

The problem here is that their PC sometimes is turned off or sleep mode accidentally. To prevent it, how we can wake up their PC by some simple script or method?

I've just bought a DrayTek Vigor2620Ln (ADSL/VDSL router/firewall with backup WAN port and 4G LTE modem built in - UK version)

I want to be able to create a site-to-site (or LAN to LAN in DrayTek's terminology) VPN via an IPSec tunnel to a Netgear ProSafe firewall I have running at another site. Simultaneously I want to be able to access a L2TP VPN Server running on Windows 2012 RRAS (behind the DrayTek at primary site), via passthrough when I'm out and about.

Having created the site-to-site VPN with a few issues along the way, I have got it working. I have also got the L2TP VPN passthrough working so I can connect from my Windows laptop when away from the main network. HOWEVER, it seems impossible to get both working at the same time. For the site-to-site to work, I have to tick the 'Enable IPSec VPN Service' under the Remote Access Control settings on the Draytek. But once I do this, passthrough of the L2TP Windows VPN fails. If I untick, it is the other way around with the Site-to-site failing and the L2TP passthrough working.

I suspect someone out there will confirm DrayTek routers simply cannot both have a site to site and L2TP passthrough connection connected simultaneously (I momentarily achieved it once, on initial bootup). I appreciate both VPN types use IPSec, however every single Netgear and Linksys router I've owned and used to date has been able to do both simultaneously with zero problems. I'm hopeful I'm missing something, but fear I'm not and the …
are on the same cluster network, yet address is not reachable from using UDP on port 3343.
I understand how to set multiple public static IPs to the WAN interface (usually eth0).  But I am in a unique/new situation (to me) on trying to figure out the following.

I am subscribing to a satellite service (no other viable option).  They offer "persistent IP's" which is ALMOST like public static IP's, I am being told (still discussing that with them).  The way they present it is:

a) Installation
b) Connect your device to the modem
c) Get an IP address
d) They manually map their DHCP address to the MAC address of your device in their table
e) Now you have a static IP (which is supposed to be routeable) - ie. Public

So, I am trying to figure out how in this scheme of things, I can statically map an email server behind NAT to this public IP.

Currently I have static mapping in my cisco T1 router where inside = outside, one to one mapping.

Moving off my older Cisco 1841 to the Edgerouter X for more functionality.

Thoughts on how to achieve that in the Edgerouter X?

I've been experiencing this issue when logging into our network from different locations including VPN where drives and folders I normally have access to are no longer available.  Some network shares fail to connect completely and some only show me some folders but not all of them.  This is very strange behavior and I'm not sure what could be accounting for it.

These sites are networked through a wan connection and has DC's at both sites that are trusted.

Hi All,

We have an older Mitel 3300 using predominantly Mitel 5212 phones. We have a dedicated VLAN for voice traffic, which is tagged on our switches alongside whichever VLAN is providing the network for the computers. We are having a strange problem in which when a phone call is made, one side is unable to hear the other (in reverse it is fine). After a few seconds this will sometimes resolve itself, or they will need to hang up and try again. On the retry both sides can usually have full conversation as normal. This happens randomly throughout the day to different number / handsets that are plugged into various switches throughout the organisation. We have had a look at the switches and they don't have any obvious errors / are not reporting they have maxed out on throughput.

We have had our support engineers look at the phone system and they cannot spot anything obvious with regards to the fault.

Any clues as to where to start diagnosing this.

Hi, Is there anyone know how to block one vlan to another vlan on HPE S5500 switch?
I have a guest network vlan 20 and I don't want vlan 20 can access vlan 8 (staff) network.
I am attempting to configure bgp peering between a Juniper SRX in HA and NSX using redundant interfaces.  There are 2 peers with associated different vlans (subinterfaces on the reth interface).  Peering is up, and the routing is in place (confirmed with ping tests), however TCP traffic is being throttled.  

throughput from the upstream to the bgp network is nominal (bidirectional)
throughput from any other reth subinterface to the bgp network is throttled. (bidirectional)

There are no dropped packets, and bidirectional traffic is seen at the sources and destinations.

Does anyone have any Ideas?  Thanks in advance.
A company has asked me to build them a new Wordpress website and they want to host it on their own servers. My concern has to do with how to create a website in a privately hosted environment, since I have only built websites using hosting company environments like Bluehost or Network Solutions, for example. I am comfortable logging in to an administrative environment and utilizing Cpanel tools but can’t visualize what it would be like in a self hosted situation?  Nor have I installed Wordpress using anything but a self-installer. Can someone give me an idea of what I am up against here, if it would be wise to self host a Wordpress site, and if there is anywhere on the net I could see visual examples of a self hosted environment?  Thank you much. I hope you understand my concerns here.
I recently resigned from my last company and have been receiving calls for new employment; however, I'm a bit confused as to how to address why I left my last company without sounding "bad".
