Dear Experts,

I have a Hp Z220 Workstation which I need to configure for remote management.

I have configured the IPv4 in the network interface, confirmed it once again that the IPv4 address has been saved.

But when it goes into Windows 10 Professional, I am unable to ping the IP address let alone access the remote management browser.

I have tried to find the software to manage the Interl AMT but to no avail or not compatible.

Can you "downgrade" Cisco IOS-XE from 3.7.3 to 3.6.8?

May seem like an odd question, but I have 9 other switches of the same type on 3.6.8 and wanted to see about changing this switch to coincide with the others. Not a huge issue but was curious if it could be done simply or if it's more in depth.

I am building a network diagram using Visio 2016.  I have created a data graphics that I want to show some information about the server to the left.  What I am trying to do is bring the text closer to the server, but not inside the server.

Below is a screenshot of my shape and data graphic.

Is there a way to bring the text in the data graphic closer to the server shape?

Any help would be greatly appreciated.

I set a group policy to allow remote desktop only from inside the network.

I set up some users to establish a VPN connection to the server’s VPN, with windows VPN service.

Will they be able to remote into their computer with remote desktop, once they establish a VPN connection, will they be considered as part from the network so the group policy will allow them to remote to their computer?

Listen Up!

IPv6 is here to stay. Removing it can break networking. Do not remove it.

SMBv1is a security hole and has been removed from Windows 7 & above, Server 2008 & up.
SMBv1 has been removed meaning you cannot connect to old operating system, old NAS devices and old printer/scanners.
SMBv1 is a security hole. Do not enable it.

Window 10 is going to update. Get used to it. The people who turned Windows 7 updates off and then blamed Microsoft when their operating got hacked and hosed caused this.

Home group has gone (Windows 10 V1803 and up). Get used to Password Protected sharing and learn how to use it. I wrote an article about this  (look in my Articles for Folder Sharing on modern computers). Do not turn passwords off.

Windows 10 is not Windows 7, does not work like Windows 7 and has dispensed with some old Windows 7 ideas. There is no going back. Get used to it.

You got ransomware from people opening email from strangers. Get a Spam Filter. Train Employees, keep Off-Site backups. It is not a technology problem - it is a management problem.

Amortize expensive software and hardware to create cash for new equipment. "I am stuck on XP because the equipment is too expensive to upgrade" is not an option. Get your accountant to explain this to you.

there is a few more things from the past that SHOULD not be used anymore from this century onward:
UNENCRYPTED data transfer
like FTP   - use scp or sftp
HTTP - use https
PPTP - use l2tp or better instead
lets not recycle this waste from the 1990's

I agree. I have not used plain FTP or PPTP for years now.

Hi guys

On the weekend, our Exchange 2010 server stopped receiving emails because the C drive was below the accepted threshold. We also use Messagelabs to route any inbound emails and outbound emails.

Once I resolved the issue today and got the C drive above capacity again, emails started trickling through. However, we are still getting emails coming through from Saturday evening.

My question is: Is this down to the original sender and how often their email system tries to resend the original email? (i.e. beyond our countrol?)

Thanks for helping

Hi

My redhat (guest OS) having issue for not able to resolve the hostname like google.com but able to ping 8.8.8.8.

I didn't do anything at all just to ensure that it can ping Google first and my network subnet like 192.168.1.0/24 when my redhat added a NAT Network adapter without issue.

After that I connect my fortinet vpn client thr IPSec and still can ping and resolve my private cloud thr hostname.

Next day I do the same thing like connect to my iPad 4G network to my Hp laptop wifi.

Can ping and resolved on my hp laptop even being connected to vpn.

The guest os redhat from virtualbox on nat can ping 8.8.8.8 but not able to resolve now.

Why yesterday can and today can't without changing anything?

Thanks.

We have a user with a HP Officejet 6830 that we are trying to setup with HP EConnected/EPrint (print over Internet).  Everything goes smoothly throughout the setup, however, upon adding the printer the dot is orange not green on the HP EConnected site.  However, in checking the printer locally he have a green check mark for EPrinting.

The user has a basic home network with a AT&T UVerse (not sure of the exact manufacturer).  Do you need to open up certain ports for EPrint to work on one of these routers?  (In the past wet set one up on a home network with a Negear router and it was plug and play--green dot next to printer not orange.

Hi,

I'm not familiar with F5 at all.  We use BIG-IP 4200.

If I need to know to which internal IP is NAT an external IP how can I check that in the interface?

Thanks

We have dozens of Windows 10 Pro workstations.  Some of them are sharing files in an "open" manner on a peer-to-peer network; i.e. the files are readily accessible on the network.  Others are more tightly secured.  
But the "open" ones keep getting changed by Windows updates.
Specifically, access to Public folders is turned OFF AND password protected sharing is turned ON.
It's not hard to fix but it's an unwarranted nuisance.

How can we nail these two settings down once and for all?
Should we resort to a Windows Task Scheduler task to run a batch file or script each night?

I am missing configuration info in the network dialog box.
MissingThe computer used to get on the Internet but was using a rogue router that had been set up with DHCP.  We turned off DHCP on that router so we can use our main router.
Now the Ubuntu 18.04 machine won't grab an IP address.

Big Business Goals? Which KPIs Will Help You
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

I have just configured a LAMP on my 10.1.1.x network.

The LAMP hits the Internet but shows an IP address of 192.168.0.109/24 (eno1).

Cable (Arris) modem is providing DHCP.

How is it possible for this to happen?  I'm thinking that I want the LAMP to have a 10.1 address.

We would like seek for advice for the Aruba’s firmware version convention.We will implement WiFi in our ware-house soon we found out our Aruba IAP 305 firmware version is 6.5.4.3

We want to integrated with our Air-Wave and AirWave mention that support Instant 6.5.0.0-4.3.3.3 ,Can we confirm if IAP version 6.5.4.3 is the same with 6.5.0.0-4.3.0.0? I am quite confused with Aruba’s firmware version convention.

The network is running on server 2012 r2.  The users have roaming profiles.  The work stations are windows 10.
One user has recently changed her name from Sarah Smith to  Sarah Jones.  I have changed the name on the user profile in AD, and access to the files has stayed the same.  The only challenges so far is the "welcome screen" during the work station login.  The login still welcomes Sarah Smith.  

How do I change the login to reflect Sarah Jones.

I have a windows server 2016 std machine that is a VM and I am running routing and remote access on it as a VPN connection, and also it has a few NICs in it to go back and forth between 2 subnets. I have a file share on it and have noticed that I cannot move files across the network while RAS is on. Or at least it's not working well at all as it took several minutes to transfer a 24k file as a test. When I disable the RAS service the files transfer at normal speeds. Any suggestions?

Working to establish IPsec Site-to-Site VPN, the local network is 192.168.0.x behind a Cisco RV130W and far end has a Cisco NSA 2600 and also has a pre-existing VPN with the 192.168.0.x subnet. The tunnel needs to support a single host on each end.

Is it possible to assign a 2nd IP Address to the PC in my network, say 10.10.20.2, and use this for the VPN?

Hi All

I have a firewall problem that I believe is switch related.  My Sonicwall is alerting on IP Spoof Dropped but all the IPs are from my network into my BOVPN link.  I think the spoof is that the firewall is seeing many IPs coming from the connecting network on the Dell 3024 switch.  It seems I am unable to turn the connection from switch to Firewall into a trunk, I thought having a list of IPs from the local network as Tunnels would solve this but it hasn't.   Can anyone give me any pointers on how to resolve this problem?

Thanks

E.
