Hi,

I have a user that is being locked out on the domain within seconds of unlocking.
I used Netwrix Account Lockout Examiner and figured out which machine was the culprit. If I turn it off, no problems, the minute it comes back onto the network it locks the user. The machine is a remote test pc running windows 7 that he rdp's into here and there.

When I run an examination everything is "ok,nothing found" but "Examing Logon Sessions" shows this:
...Failed due to the following error: Access is denied. (Exception from HResult: 0x80070005 (E_ACCESSDENIED)

We changed his password on the domain and sync'd everything, removed all mapped drives, checked services logins, made sure there were no local logins, still no joy.

Any ideas?

I have Database.mdb which is a 570 meg file on a Windows Server 2016 shared directory.  

When I drag it to  \\CPUDesk c: drive it takes 10 seconds.  This is a $400 windows 7 proiDell Inspiron 620 desktop that is 6 years old.

When I drag it to a \\CPULap c: drive it takes 50 seconds.  That is a brand new $700 windows 10 pro Dell Inspiron 15 laptop with a fast i7 chip and 8gig memory and a super fast SSD SanDisk x400.

I am shocked that an old cheap desktop is so much faster than the latest technology laptop.

At first I thought it might be a bad Cat 5 cable or switch port, so I swapped the laptop and the desktop and reran the test with the same result.

CPULap has a 1000 gig NIC which is confirmed because the network switch shows two green LEDs.  

Does anybody have any ideas of how I can trouble shoot this?  

rberke.

P.S.  At the risk of giving "Too Much Information", here are some additional facts, to muddle the picture.


I tested the copy on other cpus
*1 year old windows 10 pro laptop ($1300 quad core Lenovo t460p) also took 50 seconds.
*3 year old windows 10 pro desktop took 10 seconds
*3 year old windows 10 pro desktop took 10 seconds
* 5 year old windows 7 pro desktop took 10 seconds
* 4 year old windows 7 pro desktop took 50 seconds


* 2 month old windows 2016 server took 1 second (no surprise, because that copy didn't even go through the switch.)

Hi, I am trying to determine the best way to configure a WAP4410N, with our ASA5505, so that the WAP will have 3 SSIDs. 1, "Wireless-Inside" will allow internal users to connect to the internal network, 2 "Guest-DMZ" will allow guests access to the internet and not the internal network, and 3 "TimeClock-DMZ", which will only allow our timeclock to connect over the internet to its web instance.

Dear all,

I am an IT support for a small company consist of 5 users. I assigned a static IP address on each computer.
Around 3 weeks one of my colleague was not able to browse the connection or see the shared folder on the server until I changed his PC's IP address. This issue reoccurred again today on his PC and on another PC.
I have done a lot of troubleshooting and the last step was changing the IP address. After changing the IP address on two PCs they were able to browse the internet connection and see the shared drives.

I am wondering what is the magician with changing the IP address. Please assist me because I am looking for a solution to avoid keep changing the IP addresses form time to time.

Hi Guys,

We have an IP block from the ISP
Thus a couple of public IP's assigned, example:
196.31.231.80
196.31.231.81
196.31.231.82

Our NAT policies on 196.31.231.80 over X1 interface is working well.

I've been trying to setup additional NAT policies on 196.31.231.81, but experiencing a connection issue.
Which brings me to the following questions:

1.  Is it necessary to setup a Virtual Interface for 196.31.231.82 on X1?
(255.255.255.0)
Or could the NAT rules simply refer to X1?

2.  I tried setting up a Virtual Interface on X1 for 196.31.231.82, but it complains about the same subnet used,
What should the subnet for the Virtual Interface be?

What does it mean to be "Always On"?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

hello,  i want to use two different isp on sonicwall equipment, i want one isp as primary and the other as back up, i want it to switch automatically when the primary is down

hi experts

is this the correct answer

VMkernel is a virtualization interface between a Virtual Machine and the ESXi host which stores VMs. It is responsible to allocate all available resources of ESXi host to VMs such as memory, CPU, storage etc.

or this

The VMkernel networking layer provides connectivity to hosts and handles the standard system traffic of vSphere vMotion, IP storage, Fault Tolerance, vSAN, and others. You can also create VMkernel adapters on the source and target vSphere Replication hosts to isolate the replication data traffic.

I have recently installed an ASA5505 as a domestic firewall.

The ASA5505 is sitting behind a Netgear DM200 Modem Router.

The setup is as follows:

ADSL Line <-> DM200 (public IP is dynamic)

DM200 (private IP is 10.10.10.1) <-> ASA5505 Outside Interface (10.10.10.2) The network is a /30 subnet.

ASA5505 BT Youview interface (192.168.5.5/24) eth 0/4 <-> BT Youview box

This is a double NAT setup so Ive struggled slightly...

I have been unable to get any of the BT Channels since I installed the ASA.

I have placed the running config below for assistance:

Looking for a script that will go out and check if DNS is SET to DHCP. The script will run against all the computers in the network.  The output should only contain the name of Computers that are not using DHCP Option for DNS.

Thanks in advance

Hello everyone,
A client of mine is having an issue with their wireless.  They have been reporting that the passwords were getting rejected so I updated the passwords and then the same thing.  I have tried rebooting it, which normally used to fix these issues but now does not.  They have two ssids, one for employees and one for guest and they are configured in a virtual access point.  There are no more firmware upgrades for this model, my next step would normally be to upgrade the firmware.  We have recommended upgrading this Sonicwall as it is no longer supported as well as having a separate access point in the past.  I honestly think that this would be the only solution at this point, but out of good customer service I am reaching out to you guys to see if there is anything else that I can try.

Profile all saving in a server- network shared folder. inside the folder, for each user, it has many versions. what does it mean ? why it is creating many versions ? is it ok to delete old versions ?

For eg. for userA, there are folders like.   userA.v1 , userA.v2, userA.v3

Hi
I'm deploying sonicwall cert from a firewall to all my windows clients.
The certificate has been distributed by GPO.
I'm having a problem with java apps (idrack) which can't connect.
I've imported this to my java store but the same issue appeared.
Eventually I will need to distribute this to all my Win and Mac clients.

I purchased and installed two 2 Terrabyte Disks, for a Windows 7 Pro computer.

In the Disk Manager they show up as per the attached .jpg called 'DiskManagement1.jpg', which provides access the several drives that 1 approximately 1.00 GB and are called E:, G:, H: and J: while what is important is Disks F: and I:

This in turn shows up under "Computer" as per the.jpg called Diskmanagement2.jpg

Is there any way to make E:, G:, H: and J: NOT SHOW UP under "Computer" ?
Shows screen shot of "Disk Management"Shows screen shot of "Computer"
Help, as always is appreciated.

I am upgrading the Comware 5 firmware on HP 5120 switches HP 5120-48G-PoE+ EI Switch Product # JG237A. In the past I have upgraded them with they are offline.  I would use my laptop as a TFTP server, connect it to a port on the switch, and put my laptop IP address and switch management IP address on the same subnet. I would use the following commands (for example):

delete /unreserved flash:/<firmware>

tftp <IP Address> put flash:/<firmware>

boot-loader file flash:/<firmware>

save

reboot

Would I be able to do this with a live HP 5120 switch connected to the production network and grab the firmware off a live tftp server on the production network?

Please help. Thank you.
