So I have different users using windows laptops that are new on my wifi network.
When they open a web browser, they get an error message can't "establish a secure connection"
Dropbox has the same error message.

When I checked the proxy settings for the browser, it's set to automatically detect the settings.
I can manually enter a website, like or whatever and the internet works just fine.

Any idea's what I'm getting this error on multiple computers?

If I turn off wireless access on this M4800 and hook up cat5 directly from my router to the M4800 shouldn't I have instant internet connection without the necessity of configuring anything? I am showing "No internet connection". I know the router is functioning properly. I am 5 feet from the router to the laptop. I have tried two new cat5 cables. If  I must do some configuration to make the pc recognize that there is a signal from the router on my ethernet port available, where do I turn  it on? Windows 10.
Hello - I have a Windows 2008 R2 server that I built recently, and in the first week of use, it has lost it's trust relationship with AD twice.  What causes this?
Windows user, on a network when connected to the company network (including wifi), everything is OK, however when on an outside network, message pops up Windows Authentication failed, including Outlook. Can't connect to VPN either.
Hi All,

We have just moved to Kaspersky EndPoint security 10 ( from Sophos.
Some of the users have complained that now it takes them few minutes when they start there computer in morning and when they shutdown.
Is there anyway we can monitor whats taking up resources when the computer starts and how can we minimize Kaspersky resource utilization?

Hi Experts,
I got some errors when trying to install a Windows Service app on a production server.  The application deployed successfully on my machine, but not production\network server.

Here is the 1st error I got:
An exception occurred during the Install phase.
System.ComponentModel.Win32Exception: The trust relationship between the primary domain and the trusted domain failed

To fix the error above, I prefixed the Username with the domain (sample format:  Domain\username).  I also put in the correct password,

I then got  the 2nd error (see below):  
An exception occurred during the Install phase.
System.ComponentModel.Win32Exception: No mapping between account names and security IDs was done

Any idea what needs to be done to get my Windows Service deployed properly?  

Thank you in advance for your help,
I'm sure this probably isn't possibly, but is there a way to map 2 different network drives to the same drive letter?
The only way I can see doing it is to change the drive letter for one of network drives. Suggestions?
In this question I am asking about computers that are all connected to a 24 port switch.  I am not discussing connections from home or a different physical location.

My new laptop(CPU#13) CAN connect to my old laptop(Cpu#1) using MSTSC /ADMIN, but vice versa fails.

In other words CPU#1 CANNOT connect to CPU#13.  The connection gets error message:

The computer can't verify the identity of the RD Gateway  It's not safe to connect to servers that can't be identified.  Contact your network administrator (that's me) for assistance.

CPU#13 is my new Lenovo t460p which was purchased several months ago with preinstalled Windows 10 Pro. There was a recent automatic update and it now has Window Pro 10.0 (15063)

CPU#1 is my old Lenovo t500 which was upgraded to Windows 10 last year.< Windows 10 Pro  10.0 (10586)>

Both clients have very similar user profiles for

The SBS2003 domain controller shows the two computer profiles are identical (except one has windows 10586 vs 15063):
Their Dial-in dialogs both show "Control access through Remote Access Policy".

I logged into CPU#1 and #13; The  >system properties>remote > both show "Allow Remote Assistance connections to the computer" and "Allow remote connections to this computer".

Anybody have any ideas how I can access CPU#13 from CPU#1.


are there any common reasons why devices in a domain may not be showing in system centre, or any pointers on where to start on how to resolve? I am not a SCCM admin myself, but wondered how the device initially gets added to the SCCM database? Is it a manual process when you procure and build new devices to add them into the system.
what is the correct terminology used to get an a top level view and oversight of network infrastructure in use in your private networks, e.g. firewalls, proxies, routers, switches, wireless controllers etc. I would like to request a copy for asset management and CMDB purposes to see what interacts/depends on what, but need some idea on the correct terminology for such a diagram/document.

aside from SQL Server databases, what other types of files would need special/app aware backup processes. My understanding (albeit I am not a backup admin) is most default backup solutions don't backup live running database files, so you typically have to use the DBMS backup features and then use your backup solution to 'backup to backup'. I just want to do some assurance work that the backups our admins are doing is either using an application aware product which can handle running files such as databases, or whether they are using other tools such as the DBMS in built backup features to do them.

also apart from SQL databases, what other files need special backup arrangements, e.g. what else would not be covered by standard backup programs, in your standard windows network environment?
We would like to deploy a Windows Server 2016 machine (which will run SQL 2016) on a domain that is currently all 2008 R2 servers.   The domain controllers are 2008 R2.

Are there any issues, if we want the 2016 server to be part of the domain?

Each time I attempt to open an address to my NAS in Edge I get this error:

 The connection to the website was reset.

I type in http://192.168.x.x and get that error.
We are having some "unspecified network issues" between a Windows Vista and Windows 10 computer.  

As we are trying to eliminate causes one by one.  The ping times between these two wired computers will go from less than 1ms up to 15ms with 90%+ of the them being single digits or below 1ms.  

Is this normal?
I have disabled the Windows Firewall of my Windows 2012 R2 server, When I telnet to localhost 445, it is ok, but when I tenet to the actual IP 445, it fails.

Anyone have idea of why?

I need the tcp/445 for remote log pulling from a SIEM connector.

Good Afternoon,

We have a share on our network (Windows 2012R2) that a specific department has access to.

Occasionally the users of this department will accidentally delete files from this share. Usually we can recover the file from shadow copy or tape, but sometimes we are unable to.

I have attempted to modify the security of this share by denying delete and allowing everything else. While this does the trick, the user is also denied from renaming the file, which is not going to work.

The user must be able to do everything within this folder except delete files.

Kindly advise how I can accomplish this without the need of a third-party software.

We have a Windows server folder structure similar to the following:


I would like to prevent users from being able to delete or move folders at levels A and B.  However, users need full modify access (create, modify, and delete) for level C under all folders.  I have been able to set permissions that prevent users from deleting or renaming a folder, but for some reason they are still able to move the folder.  Is this possible or am I banging my head against an impenetrable wall?  Thanks in advance!

I work for a company where i have 150 Users all work group computers having (Windows 7/Windows 8/ Windows 10 Operating systems installed. We are planning to implement a centralized system from where we can manage users centrally and deploy softwares, push policies to the users as required.

Current Setup:-
We have a Firewall Dell SonicWall NSA3600 , 4 Cisco Switches,Two ISP connections 15 MB each and few wireless access points for wireless connectivity currently. we are shifting to a new office this month end due to the short of office space and planning to implement a centralized user management system.

Every time the user needs assistance, we have to rush into their places and troubleshoot the issues. Also, anytime i want to do windows upgrades/software deployments/push security updates, i'll have to do it manually going to each one of their desks which is a big headache and sometimes can't even do that due to the work load.

Main agenda is to, manage all the users with a centralized administrator that's it. I want all the users (clients) to be connected with a domain controller and should be managed by me and easy to assist whenever is required.

Could someone please assist me on what hardware i should purchase for windows server and what sort of licensing i'm i going to be needed, what version of windows server is good performance perspective.

Help is much appreciated!!

How do i troubleshoot? from where do i start? is there any specific tools/softwares to troubleshoot.
I AM just new in networking career. so sorry guys if its a simple question.
Our network was hit with a virus and I was forced to remove all of our network policy files under our network location \\server\share\path... etc.  Now our group policy is fragmented and now our network is being effected with those policies gone.  How would I "reinstall" or add those policies back to the network.

I have setup Windows Home Server with an X510 Data Vault for a desktop PC and a laptop.
There is a separate user account for each computer and the back up function works overnight as configured.

1. The Homeserver computer shows up in Network under Computers on the laptop but not on the desktop.
2. When I attempt to Restore or View files from a backup from the desktop, the Opening backup: stalls at 79%.

1. to be able to view Homeserver in Network under computers.
2. To be able to Restore or View files from a backup on the desktop.

I need some pictures and videos that illustrate the disadvantages of an insecure network to put in different tabs of this page

Assistance is greatly appreciated.
Hello Experts-

I am having some network issues starting a few days ago.  Initially I thought it was a DNS issue as the webpages would fail to load then immediately load once refreshed.  I noticed a few DNS log errors in the even viewer as well.  Upon checking the DNS server and NIC it seems to be ok.  An nslookup will sometimes point to the correct server and address sometimes and others it will time out.  Next I started looking at connectivity from the servers and the weird thing is we still have internet connectivity, albeit not perfect but it will load the pages 90% of the time but ping results to the DHCP and DNS (separate servers) are intermittent with a 50% - 75% loss rate, other times they will ping perfectly.  Pings to the gateway seem to always go through.  I am a little befuddled on what is going on.  I am leaning towards the switch that everything is connected to is having an issue but that'd be odd since its less than 6 months old... not impossible though.  Both servers are Windows 2008, the majority of the clients are Win7 and Win10. Any thoughts would be appreciated.  Thanks!
