My computer is a HP z230 workstation running Windows 7 pro.

Each time I try to read the www.windowssecrets.com web site, my browser (Firefox v58.0.2) tells me it cannot connect to this web site.  I have tried connecting using my other Windows computers and none of them will connect to this web site.

When you cannot connect to a certain web site, how do you determine whether the problem is in the web site or in your computer or some place else?

What software or tools do you use?

Please give me detailed answers.  I am not a network expert.

OSPF Rout metric

o
in the topology above I configured OSPF on R3 for all interfaces. R1 and R2 are configured both with OSPF and RIP. Interfaces connected to R3 are in the OSPF domain

R2 learned OSPF routes from R3 . I can see the metric is 110/20 for the physical interfaces but the metric for the route on the loopback is 110/11

I am not sure why. Though I adjusted the bandwidth , delay , mtu of the Loopback to be the same as the physical interface.

Data transfer question
Great day I am doing a migration. Moving people profile from one machine to another. I am pushing it up and pulling it down.
I am trying to locate a switch that will transfer really fast. Is there something faster than 10/100/1000gbs, is a 10gb or even 20gb ethernet unmanaged switch that is fast. keeping in mind there may be people that have over 100gb of data.

Hi Guys,

Firewall->HP Switch Layer 3 -> esxi servers 1,2

I'm a vmware vsphere 6 newbie.
I have 2 physical ESXI servers(ESXI v6) that host 30 virtual servers. vmWare vCenter 6 is set up properly. Desperatly looking for some help/advice on this.

Every physical server has 5 gigabit ethernet connections.

Connected NICs:

Management Network x1 (vmnic0)
LAN x3 ( vmnic 1,vmnic2)  (30x Vms)
ISCSI x2 (vmnic3,vmnic4)




Everything is up and running smoothly on our production Network.

Now I need to connect these physical servers to DMZ since there are some vm's that should run on that part of our network.

How should I do that?
What are you guys doing out there?

How about vLANS? Can it be set up and span multiple subnets so I can keep all servers connected to internal LAN?


Thanks in advance.

Hi,

I am trying to create a linked server on SQL Server 2016 to connect with a SQL Server 2005 server. I keep getting the standard network error/check server name message.
Any guidance on creating this would be appreciated

Many thanks

Hello,

Why can I not set a static IP address, on a Windows 10 Pro laptop, for a specific Wireless network.   I go to Manage Known Networks >  Choose network > Properties:  then nothing, no way to set an IP address.  There are some versions of Windows 10 that do allow you to adjust the IP properties for that specific wireless network,  I think.

Surly I'm missing something here?

Thanks

SSH Tunnel with PuTTY
What is and what SSH is for
Secure Shell (SSH) is a network protocol that provides shell functionality on a remote machine through a secure channel.

SSH carries various security enhancements, including user / host authentication, data encryption and data integrity, which prevents popular attacks such as eavesdropping, DNS / IP spoofing, data forgery, connection hijacking, etc.

 Users of ftp, telnet or rlogin who use the protocol that transmits data in plain text are highly recommended to switch to SSH.

Hi Experts,

I've been using a JS export code that allows me to take data that is being passed from my dashboard and exported as a new excel file (xls).  The export function allows you to save the name of the file, and sheet name.  All this is great.  What I am needing help on is how can we programmatically save the exported file to a pre determined folder (network drive)?  I am not familiar with JavaScript so any assistance would be greatly appreciated.  

This is a request that will give executives the ability to click on a report used for certifying data and have to only hit "Certify" and the csv is placed in a network drive (folder) and the executives will never have to do anything other than hit the certify button. The problem with my code now is that it saves on the local machine as a default.

I have a major problem with both my network server (Win2008R2) as well as my Win7 workstation (although the workstation is up and running...I'm using it to enter this question).  The problem began on 2/15/2018 at around 10PM and the origin was either a virus or something I did myself (from a remote location).  The timing is what leans me in the direction of myself being the cause of this issue.  I had been out....had a few drinks....returned back and attempted to access the computer at approximately the time when the problem appears to have occurred.  That said, I can't rule out a virus since I've received some conflicting reports back from my customers who have been using my server over the past 8 months to connect to and work with a software application that I sold them and provide support for.  Now, let me get to the point.  My server will not boot into Windows, so, for all intents and purposes, the server is "dead" right now.  In my attempts to recover the server, I've realized that virtually every file on the computer has been "renamed" with the following appended string:

.id-B8D8CBA7.[decrypthelp@qq.com].java

This is the reason my server won't boot since this "appended file extension" has effectively renamed every file on my C: partition including the boot files.  The same string has also been appended to certain files on the workstation that I'm currently using, but not to the same extent and seems to have affected only certain partitions on this workstation.  My…

We have a client that has a HP Color LaserJet Pro MFP M477fnw that is experiencing intermittent issues with printer.  It is in a workgroup environment with two computers (Windows 10) using Defender.  (We have even turned the firewall completely off on one for s*$(@ and giggles.)  

They are both connected to it over the wired network.  It will work fine for a few hours then will show Printing on the printer screen and just hang (as will the print queue).  A reboot of the computers (as I have been told by the employees) will start it printing again (sometime).  We have done the following to solve it:

* Factory reset the settings on the printer
* Updated the firmware on the printer
* Replaced the network cable
* Completely uninstalled the drivers from the computer, rebooted, downloaded the latest drivers from the HP website, reinstalled the drivers, rebooted the computer again
* Verified all network settings on the printers
* Confirmed static IP on printer outside of the DHCP range

This printer was bought new a couple of years ago and after all this troubleshooting and best practice steps taken to resolve the issue I don't know what to do.

Hi,

->Can PA-500 do HA, and also, i don't believe  there is any HA interface on it, so which intreface can be used as HA1 and HA2.
->And, please what is the minimum config require to get connected to live network of 40 users, and if HA is allowed to be able to sync.

Thanks for your help.

Just a fundamental LAN network questions as I am studying CCNA course

Computer A and B both are connected to a normal L2 switch and turned on. there is no DNS server configured (it shouldn't matter as it is pure L2 connection?)
what are the setups computer A pinging computer B by the name at the very first time? is the switch going to broadcast computerB's mac address? if yes, how would computer A know what is the computer B's mac?  
just trying to understand the principle of LAN communication.
It would be great if I can get some articles to read.

Thanks

Can't print wirelessly at home from HP Desktop, to HP OfficeJet Pro 6978. Problems started after upgrading to new Verizon FIOS router, with 2G and 5G networks. It took a while to get the printer working, but I got it working. But now after a week or so, it won't print, although today I printed several diagnostic pages from my PC. When printing from Notepad, it just says "Error Printing". Both the PC and the printer are on the same 2G network.

I just noticed that the Diagnostic pages kind of doesn't go through the printer software. I say that because in my printer queue, there's a document with status "Error - Printing", but even with that the Printer Diagnostics page slipped on by and printed without actually going to the printer queue.

But I can print from a MacBook Pro, no issues, even though in my Printer queue there's still a document in error.

OSPF/RIP Redistribution

I have this topology :
I have advertised networks 1.1.1.1/24 and 192.168.12.0/24 into OSPF
 then Redistributed   OSPF to RIP with metric 10. Now : 1.1.1.1/24  shows with metric of 10 in R3 RIP Routing table, but 192.168.12.0/24  still shows with metric of 1.

I am hosting a simple html webpage on Server 2008 R2 standard v 6.1 (build 7601: sp1) running IIS (v7.5.7600.16385) I have a couple apps already running smoothly on other ports.
The webpage is viewable from inside my network, but not from outside the network.

Tried switching the ports in IIS between the working apps and the html page, I get the same results the apps still work externally but the html page does not, is there a permission I am missing the bindings are simple "*:port#" on all sites.

both https://www.yougetsignal.com/tools/open-ports/ & https://portchecker.co/ show every port I am using as open

anyone have any suggestions as to what could be causing this issue?

I have inherited an ESXi environment this is minimally documented. I have been able to document location of the guest servers and the main hosts, but I have one remaining problem: I cannot identify which server is handling SRM. Some of the server are protected by SRM and this is causing me issues, as I need to expand some partitions, but can't because the servers are replicating using SRM. Os there a way to find the SRM on the network, either by looking at the host configuration or guest configuration?

Dear experts,

I came across a situation where I wish to create two subnets as in 192.168.1.1 and 192.169.2.1

The 192.168.1.1 will be my main network which will contains most of the PCs, printers, etc....

The 192.168.2.1 will be my wifi network which all wireless connections such as phones, scanners, etc...

Here is the situation:

1. only have 1 switch with 48 ports (can be configured)
2. one sonicwall firewall  4 ports in back(can be configured)
3. allow the two networks to talk to one another as in if I have a PC in 192.168.1.x and wish to access a wifi device in 192.168.2.x

Here are the things that I wish to get answered and accomplished:
1. I wish to know what will be the "BEST and SIMPLE" configuration to accomplish this task. Thanks!
2. Is it possible to connect all devices into a single switch (the 48 port switch) and have combination of networks like 192.168.1.x and 192.168.2.x together without utilizing the VLAN?

Have never done this before, so just looking for quick confirmation... Trying to figure out best way to connect this:

I will have a fiber channel SAN, a Cisco fiber channel switch and a pair of servers running ESX 6.5 with the appropriate FC cards.

I am trying to scope IP ranges for the network where this will run. So does any of the above require IP addresses? Data is running on copper over a separate switch. Fiber is for storage communications only.

I am trying to setup a palo alto firewall and I an confused on how to setup my static IP on my untrusted interface. Since the ISP gave us more than one static IP I am unsure how it should appear. Under IP4 section when I add a static IP what should I enter? I have IP netmask IP range and FQDN and what determines the static IP I assume the virtual router does yes?
