Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

You might have a modern environment with all sorts of high-tech equipment, but what makes it worthwhile is how you seamlessly bring together the presentation with audio, video and lighting. The ATEN Control System provides integrated control and system automation.

All end users (from 5 different companies/locations) in our domain login to the same application server.  Each company will have an accounts payable clerk who has 2 printers sitting at his/her workstation.  One is a "check" printer, the other is a "reports" printer.

Our software vendor's software works best when these printers are networked (assigned a Static IP address) instead of plugging into the clerk's computer via a USB cable.  I usually install these printers on the local machine with the Static IP address and have a naming convention as follows:
LOC_A_CHECKS
LOC_A_REPORTS
LOC_B_CHECKS
LOC_B_REPORTS
LOC_C_CHECKS
LOC_C_REPORTS
LOC_D_CHECKS
LOC_D_REPORTS
LOC_E_CHECKS
LOC_E_REPORTS
When prompted to "Share this Printer", I answer "No."  When prompted to "List in the Directory", I answer "No."  So, at this point the clerk at LOC_A has 2 printers listed in the "Printers and Devices" folder - LOC_A_CHECKS and LOC_A_REPORTS.  This is repeated at every location.

Again, our software vendor's software prints best when the same printer(s) for LOC_A are added to the Server's Printers and Device" list.  To insure I'm installing the same driver on the Server as is installed on the local machine, I add the Printer to the Server by IP address.  The Server then queries the printer and successfully adds the printer.  During this installation process, I'm given the opportunity to change the Printer Name.  I always use the same printer name as was used on the local …

I have a network user account recently started being locked out.  I re-enable the account and a minute later is locked out again.  Is there a way in AD to tell what is locking out the account without having to go to each server and see if it is being used to logon for a service?

I have a new Dell R620 Server running Microsoft Sever 2012.  The server has 2 network adapters with 4 ports each.   I have Hyper-V running and I have 3 VMs.  Two of the VM's are each running on a single NIC and I'm seeing Ping Times of 1 to 2 MS.  For my account server I decided to setup a team one port from each adapter for redundancy but the ping times are much slower.  Usually around 4 to 5 MS.  I would have thought a team would be a little faster.  Is that not the case of do I need to change some configuration.

The Network adapters are Broadcom and Intel.  Should I just go with a single NIC like the other VM's for a little better speed or stick with the team.

What is the best way to whitelist/blacklist devices so they cannot run when plugged into a usb, serial port?  We may want some devices to run but others we may not want to run.  Note, this machine would be windows and would typically not be connected to the network.

current'y i'm setting up a radius servers for cisco nx-os, ios-xe, ios-xr and simple ios. Started from nx-os. I've set the Avpair option in radius server to legacy ios format "shell:priv-lvl=15"  and the strange thing is that nx-os understands it and accepts as r/w and "shell:priv-lvl=1" understands accordingly as just read only. dont know if the other ioses will accept that, but maybe you can advice me - to leave it as it works, or to change to nx-os format shell:roles-network-admin.

thanks

Here is our current solution:

1. StoreSimple Device with multiple LUNs.
2. File server is a Hyper-V Virtual Machine. Luns are mounted using iSCSI to the StoreSimpe (recommended by Microsoft)
3. DFS is used to for virtual share names. No file replication other than DFS info.

AD 2008 R2 domain
Windows 2008 R2 domain controllers
Windows 2008 R2 File server

ISSUE:
- A Windows 7 client connects to the file server via the DFS share \\domain.local\Share which resolves to \\Server01\Share$
- The user CTRL-clicks on a file to duplicate it in the same directory (volume/lun) that has not been modified for over 6 months (it should
   be in Tier 3 storage in Azure). We expect a delay because the StoreSimple device needs to bring it down into Tier 1 storage for
   accessibility.
- While the file is duplicating, directory browsing and other file services on the server from other clients is extremely slow.
- Our ERP system slows down as well but it is believed that the SQL server for the ERP system is querying the File server regularly.
- When the duplication process is canceled the issue disappears.
- Network adapter on the file server is running between 40-50%
- Disk I/O on the file server is within normal operating parameters
- CPU on the file server is at 20%
- When the duplication is done on a Windows 8 or Windows 10 client, there is no problem whatsoever.

We have ruled out user accounts and user rights. DFS seems to be replicating correctly…

Worked with Vmware when trying to add an interface on a ULDR on 6.3.2 Found there is a bug, and this is fixed in 6.3.3 Workaround is to delete the ULDR and recreate and add all interfaces at the time of creation

Have been struggling with this for a couple of weeks, Win 10 Pro on a domain can only see some PC'S and servers, doesn't even see the domain controller. I have searched and applied the suggested fixes, making sure services were started, removed and rejoined the domain, still nada. I can reach all the computers on the network via \\.

Curious thing did happen when I rejoined the domain. It would not find the domain controller if I just put in the domain name, it would find it if I put in the domainname.local. Dont know if that means anything but most of the time i dont need to add .local

Thanks in advance for any suggestions.

Hi Experts,

I'm trying to boot to Safe Mode with Networking.

I am configuring the boot options via msconfig.exe.

Here are my settings:

Start up settings - screen 1
Start up settings - screen 2
When I boot with these settings, I get Safe Mode, but there are no Network adapters.
I normally have wifi enabled and Ethernet via a Surface Dock (I don't think that is enabled in Safe Mode, as my external monitors are disabled).

Regards,
Leigh

The ATEN UE3310 USB3.1 Gen1 Extender Cable allows users to extend the distance between the computer and USB devices up to 10 m (33 ft). The UE3310 is a high-quality, cost-effective solution for professional environments such as hospitals, factories and business facilities.

I have a new boss who doesn't understand what my department does.

I was hoping someone on EE has been in the same situation where they've had to put together an outline of exactly what IT does.

If anyone is willing to share what they have that would be appreciated.

If you have a chart of the IT department that would be GREAT.

Or if anyone has a link to a good site that describes IT, that would also be appreciated.

I'm having an issue that I've seen on numerous forums but I've yet to figure out...

I cannot connect new or refreshed PCs to the domain. All PCs on the network are Windows 10, our server is Windows Server 2012. I am using an ethernet connection on the network.

When trying to connect to the domain from the local account I'm advised: "That domain couldn't be found. Check the domain name and try again."
I've tried both just the name and also the name.local

I've tried disabling the firewall and IPv6 but I CANNOT get this or any new computer connected to the domain..


Any assistance would be appreciated!

This is a non-Windows AD network.  Mixed environment.
Windows/Mac/Linux

Is there a good tool to scan and list all the available hostnames on the network?
Same for the DNS.  Can I search local DNS and compile all the hostnames registered there?

Thanks in advance.

I have new Windows 2012 R2 NPS member server that was setup for the purpose of Wireless Authentication via RADIUS.  
I have successfully connect when logged into the computer and the Windows Groups that are allowed are Domain Users or Domain Computers.  If I remove the Domain Users group from the NPS Policy and only have the Domain Computer I am not able to authenticate and I get event id 5632 on the client computer.

EAP Root Cause String : Network authentication failed due to a problem with the user account.

This is a trusted computer (At least I think so).  I am not sure why it cannot authenticate

i have a customer who needs to have emails coming into their server via two WANS right now. long story.
i have set up their lease line in and everything works fine. and connected their adsl both to a dreytek 2830. i have configured load balancing so that all outbound traffic goes over the lease line. port 25 is forwarded to thier server listening on both #WANs however it only works over the lease line. if i try  a connectivity test on the domain using the ADSL line it fails connecting on port 25.
what am i missing?

Had this problem a few months ago and it SEEMED to resolve itself...but alas, it is back.
Prior posting on this issue

I have a new W10 box with Office16 installed.  I can login to system on network as the intended staff member, see all network servers/drives/printers, etc...  However, when I open Outlook and it begins to auto-configure, it recognizes the user account, asks what type of install (Exchange 2013), then fails because no connection to the Exchange server can be made.  On this system, if I login as a different user, I can configure Outlook without issue.  I can also connect via OWA.  It just seems to be getting Outlook to connect for this user.  I tried Outlook 2013, also tried from another workstation, no connection.

User at her current workstation is not reporting any issues with Outlook, it is just configuring a NEW connection anywhere.

Thoughts?

Hi Folks.
I have a situation where our Corporate Wifi ( just a name)  is what our staff uses to log in and access our Network ( only with laptops). Wifi has Single Sign-On enabled so once they are logged in to their Ad account, they don't need to provide the credentials again on the same device. We have added a certificate as well for additional security.

Q 1- The users who do a password reset while being hard wired in network ( Ethernet Cable) , there is a delay where the wifi wouldn't authenticate them. Is there a way we can diminish this  time delay for password update for our Wireless Network. ( i would imagine it probably has something to do with the Radius Servers Settings).

Q 2- Some users just randomly loose connectivity to the wireless ( laptops are brand new , they connect to other wifi, they work just fine so its not hardware related).  And if they try to connect again they don't get authenticated. We have as a work around tried rejoining the computer to the domain + renaming the computer to something else and after that it also comes back to normal.

Q3- and lastly some users cant even connect for the first time. It just doesn't let them connect.

On the Radius Server, we have Network Policy set to authenticate using Only 1 condition
- that the user trying to access CORP-WIFI is part of the CORP-WIFI security group in AD.


Any help would be appreciated.

Thanks

Veeam® is happy to provide the Microsoft community with a study guide prepared by MVP and MCT, Orin Thomas. This guide will take you through each of the exam objectives, helping you to prepare for and pass the examination.

Hi,

I am trying to understand the Microsoft product that fits this if there is one.

Ok so I am aware with on-premise active directory and group policy we can do things like folder re-direction and have people save data to servers etc. Plus have
a verious department have a shared network via AD group.

Ok in a cloud world how can we do this without an on-premise active directory if possible?

What features / product set am I looking at?

Thanks,

Ward.

Greetings,
I have a weird issue when doing a Nslookup for some of our external DNS records. If I do a command line nslookup using 8.8.8.8 all my records come back showing the results as 195.22.26.248. I have tested this from several computers off our network. Even from home computers the results are the same. If I use a Nslookup tool online I get the correct results. Even using a DNS severs from local ISPs I get the 195.x results

I have a data network on 192.168.0.x and a Voice network on 192.168.1.x
The man from BT has installed a remote access box (Fijowave) which he wants to use to allow BT support to connect to Mitel hardware.
If the Fijowave box is connected to the data switch it is on the 0 subnet and can see the Internet but not the Mitel network on the 1 subnet.
If the Fijowave box is connected to the Mitel network on the 1 subnet it can't see the Internet.

How can the Fijowave box be configured to see both the Internet and the Mitel subnet?

We have a project on offer which would require one of my techs to travel to the other side of the country. It's about 30 hours work, we estimate, however, there is a lot of time where data will be migrating where there is no requirement for him to be present, maybe upto 3 days worth. He would need to be there for the start, maybe hang around a few hours to make sure it will migrate smoothly and then on call in case it fails, then a bunch of work at the end. I am trying to work out the fair way to charge for the work, given he will need there for long periods of time not really doing much. It's not worth bringing him back for that, plus flights etc, so I am trying to work out how others charge for that work? Do you charge a daily rate or something else? I assume the customer pays or provides accommodation and what about meals etc?The work is for a large tertiary organization.

I will be migrating a Google Gmail email domain to Office 365.

I have gone through and completed all the required steps as documented on the Migration Wiz website to do this.

I have created the required TXT record within this company's external DNS provider (asmallorange.com) and have been told by the Office 365 domain wizard that I need to add the records shown in the screenshot to our external DNS provider (asmallorange.com).

Is it possible for me to add these records to our external DNS provider (asmallorange.com) while leaving the existing records for Gmail in place?

I want emails to continue to go to user's email accounts within Gmail. The only thing I want to do now is to finish the domain verification of the domain name that is currently being used by Google/Gmail so I can then use the migrationwiz.com website to migrate the email from the Gmail servers to the Office 365 servers.

Then once this migration has completed I will replace the external DNS Gmail email records with the Office 365 DNS records shown in the screenshot and will create new Outlook profiles for all users so Outlook will connect to the Office 365 servers for email.

What I need to do now is to finish the email domain verification within Office 365 so I can then perform the migration wiz migrations (while we coninue to use Gmail as our email service provider--but I don't want to interrupt any future emails from arriving at the Gmail servers until I officially cut the online DNS …

A client recently asked my help with obtaining and maintaining PCI compliance which was being required by his merchant services provider. There are a lot of internal "Policy" items involved, so I wondered if anyone knew of a pre-done package that could be integrated into the employee manual to achive these requirements rather than re-making the wheel, so to speak. I also have questions about PCI compliance in a small (10 employees) firm - the questionaire requires a lot of overview nd log checking, which if the entire network is subject to these rules, would be a rther daunting task. Has anyone gone with setting up a single workstation on an isolated VLAN in order to simplify this process?
