Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.

U-verse WIFI Extender on AT&T Internet 100 still intermittently drops U-verse, WIFI which is resolved  by rebooting everything. Bizarre, less than 2500 sq ft so the Att Smart Extender shouldn’t even be needed yet we installed it to test. Syncd ok and improved some. Have a second other extender; different mfg type. Any downside to using 2 to test?  All HW devices from ATT have been either replaced or upgraded. The intermittent dropping of signals at somewhat repeating times of night kind of nuts!

insights appreciated.

Dear Experts

We are planning to implement surveillance system in our factory for 24/7 recording footage and approximately 25 to 30 cameras  with feature of Night Motion Detection,  we prefer to have backups scheduled and replicated to head office our  factory and head office are connected with MPLS network. Synology has Surveillance solution would like understand does this serve the above requirement, it is also very much important for us to have every 4 hours backup and the same is secured and copy to the head office hence NAS box replication is required, please suggest.

Hello Experts - I'm looking for a good MSP that can assist me with helpdesk and IT projects for a medium sized architecture firm in NJ and PA. We're also looking at acquiring an office in FL so a company that has a presence up and down the east coast would be ideal. Thanks in advance for any recommendations!

Hello all and thanks for your time and expertise.  I would love your input regarding the proper permissions to delegate to an entry level tech.  The previous IT Director left my school district.  Please note he treated the Domain Admins group love a community playground as every tom, dick, and harry were allowed to be members of this powerful group.
That said I've since cleaned up this group and now only myself and another network administrator have access to this group.
However, there's a tier one tech who had access to this group who is complaining.  Please note he has zero IT background, zero certifications,  but is playing the i need access to do my job card.
He has access to the local administrator accounts to address one-to-one issues which is essentially his job.  He has full access to the imaging server to image computers and he can join and disjoin computers from the domain.  
I know as I came up through the ranks and worked on a help desk or in tier one jobs I never had server administrator access which is essentially what he wants.
I also asked him if he would like to get trained up to eventually become a server admin and he said no.
Basically if a problem required fixing dhcp, dns, AD, etc he would have no clue how to fix these things anyway so he doesn't need the access in my humble opinion.  
I'm just wondering how you good folks would deal with this issue.  I've been in IT for 25 years and have never experienced a guy with no background trying to dictate…

Have been using VisualRoute 2010 for years to help with our remote equipment installations.  In general it is helpful and can usually give me enough info to take the troubleshooting to the next step.  However, it appears that it has not been upgraded or improved in ages.  

And while it is useful, having more tools that can drill down further into latency or bad hops, etc., would be a welcomed advancement.  And I also have heard that the way it handles some situations causes it to read things as dropped packets when that is not the case.

QUESTION:  So does anyone know of a good tool that has the easy UI of VisualRoute that is more up to date and refined and powerful?  

Any help is much appreciated.  A small portion of my work relates to tracking down non functional remote equipment but it is that part of the job that is most stressful and least enjoyable.

Thanks

I have Linux 8 enterprise running on Oracle VirtualBox 6.0.10 and the network connects but I can get any traffic outside of the VM. When I run IP ADDR to get which networks are valid and then I run IFUP for those that show down I get Error: Connection activation failed: No suitable device found for this connection (device ### not available because profile is not compatible with device (mismatching interface name).

I have been going through what I can find on the web with no luck, any help is appreciated.

I am working in Service Now focusing on CMDB - the machine database. I would like to export all of the VMs and note what applications are associated with each VM. Is there a way that I, a common user, can accomplish this? I see a reports generation tool but I quickly got into the weeds with all the options. The report is very simple: Server Name, Applications

I have attempted to configure netflow v9, but I am not able to generate any flows within my 3750X switches. Should I add more configuration to my netflow module to get the flows to be read on my solarwinds NTA server? Or should I switch to netflow v5 to accomplish this task?

Here is my configuration & I am using IOS 15.2(4):

We have SolarWinds NTA and NPM installed but our devices are not sending flow information (that's what Solarwinds told me) to the database.  e.g. Netflow Sources.

We are the Society for the Prevention of Cruelty to Animals Los Angeles, non-profit.  I do not have much money to spend so I am hoping someone is willing to help us get this configured properly?

I can pay a little.

Setup:
Cisco Wireless LAN Controller with version software version:  8.8.120.0 and Image version: 8.5.103.0
 3x Cisco Aironet 1832 Access Points controlled by the Cisco Wireless LAN controller

I have a client with the following problem.  Basically there is a team that works from their Virtual Machines via Hyper-V.  When connecting via LAN cable, they do not experience problems. However, it is necessary for the team members to roam within the building between the Cisco Access Points and connect to the network or internet, when they do this there are issues with the connection.

Example Client connecting:
Dell Latitude 5580
Windows 10 Pro
Hyper-V Role installed
Core i5-7200U @ 2.5GHz
8GB Ram
500GB HDD
Wireless LAN Adapter updated to latest version via Dell Support Assistant

Basically you configure your Hyper-V Virtual Switch Manager to work with your Wireless Network Adapter.  I have attached a screen shot named Hyper-V Virtual Switch settings.docx with the configuration.  

You are connected to the SSID that is being broadcast by the Cisco WLC 3504.  You start your VM and boot into Windows 10.  Your VM will display that you are connected.  But once you start testing your connection, you'll see that your VM is getting constant time out to Google DNS 8.8.8.8.  In the same time, you will run the same ping request to DNS IP 8.8.8.8 on your laptop (Hyper-V Host) and you will get a constant reply for a let say 20 lines.  Then the …

Users on Windows 10 PCs are not seeing all search results when searching through network shares that are stored on a file server with Windows Server SBS 2011.  Windows Search service is installed and we've re-indexed the server multiple times.  The only potential solution we've found is to restart the Windows Search service every night but even then it does not seem to help.

Trying to lock down Samba (SMB) to just an Active Directory group instead of any domain user as it is currently setup. Our smb.comf:

    # Samba versions 3.4.0 and newer have replaced "use kerberos keytab"

We are an MSP - and want to know if there is a technology that can perform license management to ensure licenses are always trued up?  These products are sold via separate vendors, and not all out of one portal:

Trying to see if there isa technology with API's that tie it all together.  If not what is the best alternative short from treating each as an asset/configuration.

I have 3 Smart-UPS 1500 with what i believe are AP9630 UPS Network Management Card 2 in each one. We recently had a power outage where the main network switch lost power before the ups's shut down. The UPS network card was trying to send notification emails but could not due to no connectivity to the email server. Now when the UPS sends out email such as a self test passed, the email that gets sent out is 2 or 3 email notifications old. It like the email is queued in the network card and when a new email event is generated, it sends the oldest one out. Is there any way to fix this so that the email being sent out is the actual event vs an event that is 2 or 3 events old?  Prefer a way to do this without shutting down ups..
