Hi All,

We have an older Mitel 3300 using predominantly Mitel 5212 phones. We have a dedicated VLAN for voice traffic, which is tagged on our switches alongside whichever VLAN is providing the network for the computers. We are having a strange problem in which when a phone call is made, one side is unable to hear the other (in reverse it is fine). After a few seconds this will sometimes resolve itself, or they will need to hang up and try again. On the retry both sides can usually have full conversation as normal. This happens randomly throughout the day to different number / handsets that are plugged into various switches throughout the organisation. We have had a look at the switches and they don't have any obvious errors / are not reporting they have maxed out on throughput.

We have had our support engineers look at the phone system and they cannot spot anything obvious with regards to the fault.

Any clues as to where to start diagnosing this.

Cheers,
Paul

ASA 5508 failed.
Received a new ASA 5508.
via ASDM I've restored from my latest backup config.
Everything looks great with the exception of the VPN Certificates.

Shouldn't these have restored as well?
I was careful to check the "all ssl vpn config" on the restore options.

VPN users receive "No Certificate" when attempting to log in.

We have a Cisco 6509E chassis as the core of our network.  We are trying to run our FOG (Imaging software) server and we are finding multicast is not working through the switch.  We tested this by plugging the server into a variety of other switches that bypass the core and multicasting works perfectly.  I am unsure what settings could be different as I have compared IGMP Snooping and the portfast settings with the switches that work when the server is plugged into them.  

Any ideas?  It is running SUPT2XL as the supervisors running 15.1 on them.

Hi We have a fail open policy set. Can someone advise on the quickest way to simply completely turn off scansafe cws using asdm. briefly   - I'm not after a bypass for 1 IP- just want it off briefly while continuing to allow web traffic to flow and then quickly turn back on - - since I have a fail open policy set is it simply a matter of just removing the tower IP address set  in  configuration - device management cloud web security - by having nothing here (removing) will this turn off CWS? - thanksimage from asa Thanks

Print server: Windows 2012R2
Printers in question: All -- specifically Ricoh multifunction devices
Clients: Mix of Win7 and Win`10 -- both exhibit behavior

When a client sends a print job to a network printer, the job goes into queue paused.  It sits there for about 2 minutes and the prints.

How can I make this not happen?

I have tried setting the printer setting to print directly to the printer and restarting the print spooler.  That did not make a difference.

Any help would be greatly appreciated!

I am setting up a new network and I would like all client machines (win10) to use Azure AD (the free options with office365 biz premium)
We need a local windows file server (for big design files) and I don’t really want to set the server up as a local domain controller and would like to connect it to the Azure AD as a member server and allow users access to the local file shares using their Azure ad credentials controlled in Azure AD.
Is this possible without creating local accounts for each user to access the local file shares. I am familiar with using AD connect with server 2019 essentials which will make the local server the Primary domain controller and configuring it in that way, but Id like to keep Azure ad a the primary DC if possible?  If there is another or better way, please advise.

Has anyone successfully set up an Open VPN connection with a Windows 10 PC and a Grandstream GWN7000 acting as an Open VPN server?  If so, can you share the configuration file that works?

I have just installed a new network with one server, configured as a domain controller running Windows Server 2019 and about 10 workstations running either Windows 10 or Windows 7.  This is something that I have done successfully numerous times.  However, this one is causing me problems as computers are not getting IP addresses or DNS from the DHCP server and even when they are given static IP and DNS, they do not get Group Policies, for example, mapped drives or folder redirection.  Even those PC’s that have been given static IP and DNS still can’t reach every web site, including their own. Roaming Profiles do appear to be working.
On one PC that was showing an IP that may have been setup statically by the owner (who was away so I couldn’t ask him) I flushed the DNS and released the IP address and re-booted the computer.  It failed to get any IP.

There was a previous server that was in use prior to the company moving to new premises and we were instructed to use the same domain name.  Each workstation was taken off the domain by making it join a Workgroup and was then joined to the new domain (of the same name).  However, this was only possible with static IP, etc.  All the workstations are now members of the new domain.

The old server had started to develop problems before the office move and is inaccessible.

Server has a static IP: 192.168.11.10
Default Gateway (the router): 192.168.11.1
DNS: 192.168.11.10

DHCP has been setup with a scope of 192.168.11.2 – …

Have a client running Server 2016 Standard R2 with Essentials Role. They were purchased by a larger company and are in transition. As part of the change, they are now using the new Owners VPN Solution, so the remote access feature of Server 2016 is not required (and is sometimes confusing users).

Not sure of the best way to remove it - just remove the Remote Access role? Will that remove the Network Connection link and the VPN Adapter from Network Connections (without causing any other  problems)? Or is there a better way of accomplishing this?

I don't care if the Remote Access solution stays in place (as it doesn't work anymore), I just don't want users to see the Link and Adapter.

See screenshot for details.

We've got a bunch of VMs running Windows Server 2008 R2. One is the domain controller, the others are members. Each of the VMs has two virtual NICs in the same LAN (192.201.201.0/24 [old] and 172.16.0.0/16 [new]) as we're moving away from the invalid 192... network.
We created DNS records for the VMs' IP addresses in the new 172.16.0.0 network while deleting the invalid ones from 192.201.201.0 – but they keep appearing again, no matter how often you delete them! How do we get rid of them once and for all?
(Before you ask: Yes, the "Register this connection's addresses in DNS" box in "Advanced TCP/IP Settings" is unchecked.)

Dear Experts,

We have two Fanvil C600 phones in the office.

One is working well, the other is just showing a blank screen with the led indicator "red".

I have done firmware upgrade (pressing back and home screen button) and reboot the phone but still showing black screen.

I am not sure of wiping out the config as i have not done any backup.

Connected phone to network, the wan ports says "1000 mbps" but I am not able to ping the static ip address

The phone displayed an IP 192.168.1.179, but I cannot ping it.

Connected to lan port of phone but there is no connection.

My company is currently deploying Windows 10 workstations, replacing current Windows 7 machines. Out biggest hurdle appears to be migrating  user data from the old Windows 7 workstations to the new Windows 10 computers. We would like to I mplement a fast and easy method to accomplish this task on each user’s computer (one at a time)! We are currently employing a simple copy and pasting the user profile from the 7 machine to the 10 machine.
                         
                        This method is working fairly well but I know it can be accomplished more easily and more efficiently with a script run from the command line, e.g. Xcopy or Robcopy. The problem is both commands require a lot of switch options to choose from and I am not really comfortable using them. We first attempted to use Windows easy transfer, but it was only used to copy or move the user profile from the user’s workstations (Windows 7) to a storage location across the network to another Windows 7 machine. From that point we would copy user data from that centralized Windows 7 storage location the the new the user’s new 10 machine! I know that last step seems a bit much, but in migrating the data we wanted to make sure the user data was in a secure location on the network.
                       
                         Can someone provide me with an alternative method to migrate this data? Third party applications are forbidden in our org. I would prefer to employ Robocopy if you guys can write …

I'm asking for the best way to replace VMware ESXi hosts with new hardware.
We currently have HP Dl380 servers Gen 9 hosts running ESXi 6.5 and are looking to go to HP DL380 Gen 10 ESXi 6.7
We have four 10 GB network Adapters in each server , each connected to different vSwitchs.
The new hardware will also have Four 10 GB adapters and will end up being configured identical to the Gen 9 server.
We are running vCenter Server Appliance 6.7.0.14000

What is the best way to install the new servers ? and end up with the same configuration as the old servers ?
Can I backup and restore the VMware configuration ?
Let me know your best experiences with accomplishing a replacement like this

I discussed about Velocloud SDWAN w/ Aaron Tomosky in past and he provided a great deal of insights. This time my question is very brief:

Can VEP 4600 Device for Velocloud SWDAN accept a fiber handoff, our internet provider can only provide optical handoff.

Hi,
 
 The "NVWatchDogService" service on our Windows 2012 R2 server stopped working,
task manager status shows this service "Starting" even after reboot.

There are two Event Viewer errors when stopping and restarting this service:

  Event Error 1.
Description:
Service cannot be started. System.ApplicationException: Failed to start java Service.
   at ShunraBootstrapperService.JavaStarter.StartService()
   at ShunraBootstrapperService.BootstrapperService.OnStart(String[] args)
   at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

   Event Error 2.
Description:
Error while creating file: Access to the path 'C:\Program Files\HPE\NV\OpenJRE\bin\NVServicesJ.exe' is denied.

Suggestions are greatly appreciated.

We have 2 network policies set for our Radius clients;
1) Allow VPN connections (to VPN user group)
2) Grant priv 15 access to Cisco devices to admin group


Our issue is that if we have is that only the first policy is being processed - the VPN policy is first then we are unable to get to privileged mode on our Cisco devices, if Cisco is first then users cannot authenticate over VPN as this is being rejected by the Cisco rule.


I believe this was working in the past, so am unsure whether this is a configuration problem or the issue lies elsewhere. Nothing has changed that might explain this problem.


Thanks in advance.

I have 2 PCs that are both connected to the same WiFi network.  Both PCs are on the same work network, both have the same workgroup name and I have toggled network sharing off and on - on both of the devices.

Neither can ping the other.  However, where it gets strange here... If I run simultaneous cmd pings of each other, #1 PC starts successfully pinging the other, but stops if I stop the ping attempts from the other PC to it.  #2 PC pings never resolve.

Both devices are Dell Optiplex 3030AIO and on Windows 7 Pro, Service Pack 1

I followed the instructions to create an offline network installer for Visual Studio 2019 Enterprise.  I have tried everything I can think of to get it to install from that cache, but it just keeps using the downloader.  The command I am running is:

vs_enterprise__142530824.1536088995.exe --all --quiet --wait --norestart

The instructions mentioned something about using the layout, but the install layout command doesn't actually seem to have an installer which is super odd.  Just looks the same as the command to create the offline cache.  Any assistance would be greatly appreciated so I can stop downloading 50gb of data for each client install.  Thank you!

I'm getting a bug in a macro that I have run successfully before but is suddenly bugging. The code is looking for an unread email in a sub folder in Microsoft Outlook and opening and saving an attachment in the email, in a specified network folder.

As I say, it used to run effortlessly but now I get a "Type mismatch" error on the line in yellow, as seen in the attached workbook.

The IT department here is useless when it comes to solving anything to do with Excel, so I'm hoping there's a way that one of you knows to fix the bug. Please take a look at the screenshot in the attached workbook and let me know what can be done. If it can't be fixed by me within the code, then a network level solution might be understood and implemented by someone in IT here at work.

Thanks!

If I public explorer or excel on xenapp citrix server or remote descktop to open this file it is a good idea?

Setting up Cerberus FTP server.
We have a user who wants a ftp server in his network.

I have created 4 or 5 CSR requests for a ssl certificates and all it creates is a domain.com cert.
I need it to create a ftp.domain.com cert.

No matter what I put in for the name of the cert it is always the same. domain.com

I created a DNS setting on my server to point ftp.domain.com to the ftp server and it does connect externally.
But when I connect it shows certificate error.

But when I connect to the ftp server it does show that im connecting with the ssl connection using TLSv1.2.
So the ssl sertificate is doing used but the cert name is only domain.com.

I'm guessing since the names don't match. That's why I'm receiving this error.

IS there a way to create a certificate with another name.

Would I have to create a wildcard or San Cert?

I have 2 of PA-3020 firewalls. Is there a guide on how to do the cabling so that they are setup correctly in active/standby mode? For example I don't know if my ISP modem is supposed to have a cable going to both same ports on both PA-3020s.
