Good day,

Recently deployed two Dell SonicWall NSA 3600s with High Availability configuration. Between our two sites, our ISP provides us with an MPLS link (primary connection). We also have a VPN connection between the sites.

I would like to have the VPN kick in when the MPLS link goes down.  I have tried to follow SonicWall's guidance, but based on what I've read, the monitoring requires certain information.

I am seeking guidance with implementing this fail-over.  Any guidance will be appreciated.  Network diagram attached.

I suspect I bought the wrong thing and I need advise on how to do this right.

My network is a mixture of Cat 5 and Cat 5e cable connecting student and teacher workstations. As we move into the future, I thought this would be limiting our data flow.

I bought 1000 feet of Cat 6a solid core shielded wire. It is twice the thickness of the cat 5e and clearly will not fit my normal RJ 45 jacks.

Can I use what I purchased somehow?

If not, what do I need to get?

Should I just stick with the Cat 5e that I have?

Thank you.

This is the full error message:
“Outlook cannot log on. Verify you are connected to the network and are using the proper server and mailbox name. The Microsoft Exchange information service in your profile is missing required information. Modify your profile to ensure that you are using the correct Microsoft Exchange information service.”

Followed by other error messages. See attached PDF for screen captures.

The only solutions that we have found to work (temporarily) is to delete and recreate the user's Outlook profile. However, the issue returns about a week later.  We have also tried the registry edit for "ExcludeHttpsRootDOmain".

Hi All!!

Is it possible to isolate a small linux box computer from the rest of my home network but still have internet capabilities. My home network connects to a single router which has various devices connected to it, such as Windows machines and other devices (not many but some).

The ideas is, if the linux PC or other devices are compromised, it will not affect the others. I would also like to to port-forward the linux box for remote use. So by isolating it from the network i can minimise the risks if any.

I understand that the likelihood of Linux devices infecting Windows (or vice versa) is rare but I'd still like to achieve this.

After doing research, i have come up with the below...

  • Installing/Configuring A/V on the Linux Terminal
  • Using IPtables to restrict other devices accessing. - Complete newbie to this but would appreciate some guidance.
  • Different IP Subnets.

I would very much appreciate it if someone would be able to assist me in understanding and designing a solution.

Thank you!!

We have a linux server that downloads and uploads images for clients.

We need to know how much data is being used on average.
I have rx and tx from a sonicwall report but it shows from various IP addresses and I would have to add it all together.

I've saw I can use something called vnstat but i'd rather be able to do it without accessing the machine if possible.

What is the easiest way?

Hi community,

I work for a very large multi-national company that has a significant investment in Microsoft technology for its directory service and uses HPE Clearpass for wireless authentication.

We operate a predominantly wireless environment using EAP-TLS as the authentication method. We currently only use 'computer authentication' to authenticate a device to the network.  I would like to use 'computer and user' authentication for a number of reasons. One is that we typically don't revoke machine certificates and two, the users show up in our infrastructure as the hostname and not username, so it makes it difficult to troubleshoot.

I'm told that the reason for this is because when a machine is built by the build team it is built, then joined to the domain. The machine then gets a computer certificate. At this point the machine is issued to the user. If we have 'computer and user' authentication specified we see the machine getting occasionally dropped from the network and as such we have to revert back to just computer authentication.

I was wondering if anybody had any experience with a process similar to ours above. We use EAP-TLS with certs on both the client and the HPE Clearpass server, with the correct chains on each.

Thanks

We have a customer with a very small network, 1 x Server 2012 R2 server and 3 pc's. Everything has been fine up till this last couple or 3 weeks. All the PC's (1year old) lose DNS resolution but not all at the same time but within a few minutes of each other. So when running an nslookup it does not resolve either internal pc's names, internal domain name or internet lookups. Although if you do any of the following it works immediately:

Removing the network card and reinstall
Unplug the network cable
A reboot
Replace the network switch.

This will work for a while, maybe a day or less then we are back to square one. The Server NEVER has this issue and there is no information that indicates an issue in the logs. We have Server monitoring and we never see the server dropping either for a short while or longer.

Any Thoughts?

Regards
Dave

Hi,
Please do you have an answer for my situation?

Print Server = Windows Server 2012 R2
Client Machines = Windows 7

I have already added our printer (Samsung) and I am deploying through GPO which works fine. However, when I have added the Fax Utiliy (Which sets up as a seperate device) this does not deploy. I tried to add the Fax Device manually on a client machine and I am prompted to install drivers. I click "install" and it fails with the error 0x000003e3. I believe this is why the GPO is unable to deploy the fax service.

The fax service is on the same IP as the printer object so I cannot add it using LPT1 with IP address as this is in use by the Printer function. I have to create a Samsung Network PC Fax port.
How can I configure this so that users are not prompted to install drivers that then fails with the error? I believe I will then be able to deploy through GPO to my users.

Many thanks
Pete

There is a File Server 2008 R2 that for some reason certain clients on the network cannot access. Its very weird and I cant seem to figure out what is causing it. Its been happening for some time, first of all one of the other 2008 R2 server could not connect, this machine was in the same domain even on the same ESXI VM host. It seemed to happen to only that machine for a while so I didnt think much of it, then one other user who connects via VPN got the same problem, I was able to resolve it for a couple days by disabling the firewall on the mahcine, then it stopped working again, and wouldnt work if I disabled and re-enabled the firewall. I set that user up with an alternative method to access the files. Now it has surfaced again, two other users in a remote office that also connects via VPN is having the same issue, the weird thing is that there is 3 PC's in the office, and 1 of them has absolutely no issue connecting, so I think the fact that these are VPN users who seem to be having the problem is just a coincidence. Where as the other two users just stopped working one day.

This happens under any user account, domain admin or domain user, I can ping the server and get responses, I can even RDP into the machine, but I cannot access the DFS file share.

I have removed and re-added the file server from the domain, I have done the same on the problem machine, changed the IP of the problem machine, nothing makes a difference.

I had posted a question about having issues with esx hosts on vlans off a flat network and configuring iscsi from esx 6 to equallogic PS 6000. The conclusion to my issue was that the dell equallogic MEM was not installed and configured. My Equallogics were end of life and Dell will not put them under a support contract so i can gain access to the MEM. Has anyone come across this an know of an alternative or any way Dell will do this or a third-party? Our budget is small and we cannot just purchase a new SAN.
Thanks

I have a laptop that can connect to wireless and wired networks (detected) but has no internet (unidentified).

When setting static to the network, detects network name but no internet.

Cannot manually start the service.

Also cannot navigate to 127.0.0.1 or localhost - access denied.

I have scanned for malware, checked that everything is set to DHCP, re-installed NIC driver, reset using netsh int ip reset, netsh int tcp reset, netsh winsock reset.

Minitoolbox showed an error saying an attempt was made to access a socket in a way forbidden by its access permissions.

Any help would be greatly appreciated

I have a remote site with no local tech support. The gateway is a Fortigate firewall. Recently, when trying to sign in to edit firewall rules, I have started getting a logon prompt describing level 15 access and referencing an IOS certificate that cannot be verified. Sometimes it allows the https Fortinet web page login, and sometimes it produces the logon box- obviously a Cisco device. I have tried using an IP scanner but it doesn't allow to browse that IP (Advanced IP Scanner has a dropdown that allows you to see available resources at an IP, such as web pages and FTP sites), and I have not been able to connect via SSH (The only shell option I have is within the Fortigate web administration, and I can't get the page to load reliably for obvious reasons). This site is 3/4 of the way across the country so traveling there is out of the question. I cannot just re-IP the Fortigate for two reasons: I can't get it to save changes, and I can't take down the plant's production gateway from across the country without any kind of guarantee that I'll be able to rescue the device or limit downtime. My goal is to identify the Cisco device, possibly by obtaining the serial number so I can find out who owns it and have them correct it's IP address. I'll welcome any advice as to how to get to that point... Anyone? I appreciate your help.

Hello Cisco Experts,

I am learning how to setup the site to site VPN between two locations but it's NOT working for some reason (it's failed when I pinged the 172.16.1.1 from 172.16.2.X network .... I also tried to hit a web server (172.16.1.xx at port 80) and no luck ... it seems some sort of settings is missing?  I configured the site to site VPN with the ASDM wizard and it didn't give me any error message.  So I hope someone can shed some lights here for me?  Thanks in advance.

Dear guys, I have this scenario:
- The original IP network which ISP provide: 13.14.24.160/28 (no worry, it's fake)
- I don't know why the IT guy who worked here before request ISP to split that network to 2 subnets: 13.14.24.160/29 and 13.14.24.168/29
- However, I was handover the instructions to get Internet for LAN network as the attached picture without any other explanation

Can anyone help me to answer these?
- Please explain the way end-users in LAN network to go the Internet. Which IP network should we configure in users' PCs?
- Please give me some ideas that clarify the purpose of the splitting?
- Can I place the pfSense firewall in the Router position? If so, is there any device/configuration we need to focus?

Many thanks as always!

I've been using OPENDNS on my Netgear R7000 for over a year - it successfully filters out undesirable items from all computers on our home network.  A few days ago I noticed that it still blocks when using tablets (iPads / iPhones) but is no longer work on any hard-wired computer.  Been trying to troubleshoot this for days - no luck.  Have tried all suggestions in their forums (https://support.opendns.com/hc/en-us/articles/227988707-Why-OpenDNS-is-Only-Working-on-One-or-Some-of-my-Computers-Devices#scenario2) - no luck.  Anyone else had this issue?

Hey Guys,

I have a UniFi Switch 8 150W, 2 UniFi AP AC LR and 1 UniFi AP AC Pro.  Do I leave the channels to Auto?  Also, do I assisgn static IP address to each or leave APs as DHCP?   By default does it use both bands 2.4 and 5 Ghz?   Thanks.
