Hi all,
I need your help!
A new company supplier needs a VPN LAN to LAN with our Office. Remote router it's maybe a Cisco router (I don't know), and on my site, we use a Cisco ASA firewall. The requirement is that a public IP address is used as the encryption domain instead of our private subnet. That's ok, I did it, and it's working with a static NAT between a single server private IP address and a free Public IP address. But now I have to do the same with a private IP server address that is not on my local network, but I access remotely via a static route (it's a server in a branch office). I tried to do the same configuration with a static NAT, but it's not working, obviously.

I appreciate your suggestion.
Later I'll try to draw a schema.

Thanks you all

I want to create a PowerShell command that will set what I see using gpedit.msc on a Windows 10 workstation:

Administrative Templates / Network / Lanman Workstations / Enable insecure guest logons      [ set to Enabled]

I've researched it to the point of frustration and haven't figured it out.
There must be a way that doesn't require a Yoga class.

I'm planning to buy a 2TB storage and I would like to know if I can create this as a network drive so I can use it to save my work.
So how would I begin to do that?

One of our many workstations, (1803 build 17134.407) shows this unfamiliar message when trying to access shares that are normally available:
can't access shares with normal settingsThis happens with the network Private.
The ONLY fix seems to be to edit gpedit.msc / Administrative Templates / Network / Lanman Workstations / Enable insecure guest logons / set to Enabled on the CLIENT.

 "Not configured" (like  "Enabled" here), is supposed to have the *same* effect.

I'd like to know what's going on.  Not just how to fix it as I can already do that much.  This is most unusual and, thus, concerning.

Are we going to have to start setting this on all our workstations for common shares?

We have a network location that has Windows 10 computers and about 200 users that have iPads tethered via usb.  We are trying to complete our inventory of the iPads, but are not able to locate a couple.  Our mobility section tells us that the iPads in question are powered up.  Is there a way to detect the IP address or MAC of the host pc?

Dear Experts - i have the following setup:

laptop/host: win10 on 10.10.10.x
rhel6 vmware vm: nat on 192.168.14.x

from rhel6 vm, i can ping anything on the 10.10.10.x subnet, but not the reverse.

could you please help me make the configuration changes so that the two networks can talk to each other? thanks!!!

hi guys

We have a load of Watchguard Access Points and they are connected to a Draytek 1100 PoE switch. This switch is then connected to our backbone switch which is a Cisco 3750.

We have set DHCP on the WiFi network that the access points are on in a way to be from 10.0.5.20 on wards and the management IP of this Draytek PoE being 10.0.5.6. Every single day, people complain about not being able to access the internet properly and then it fixes itself again. Then it happens again.

When they do complain, I end up not being able to access the management IP page of the Draytek on 10.0.5.6. This makes me believe that it is in fact this particular PoE causing the issues we are having.

Could that be the underlying problem?

Thanks for helping

I am trying to look for the term wavelength of light varies between single mode fiber and multi mode fiber. I am looking for an analogy to disturb them.

VMware statistics over past 30 days

Have a request from a customer who is looking for the below

What statistics do you have? For example, do you have the following?
• 1. CPU usage
• 2. RAM usage
• 3. Disk Reads
• 4. Disk Writes
• 5. Network Reads per interface
• 6. Network Writes per interface  
7. Are they available per process?
8. Are they available per thread?  

Customer has 5.5 vCenter, no vROPs, i am used inbuilt performance graphs and results and RVtools

Whats the best way to look at above over a 30 day period? Is it possible to do this, am I better off with Power CLI scripts, if so any good ones available?

Windows 10 pro workstations, ESPECIALLY SSD's, lose mapped drive connection with file shares on a Server 2008 R2 server.  Everything fine after a restart.  No problem initially joining the network or setting up network shared apps like Timeslips or addressing network shares.  It's just some sort of timeout/standby/sleep feature that kicks in and I haven't found a real cause or solution.  I know it's anecdotal, but I've seen this over several clients in different locations and I "know" it doesn't happen with Windows 7 machines OR with standard HDD's.  And, there isn't a set timing, other than it does not seem to happen while a user is actively working and engaging...this is good obviously, and would seem to point at a standby mode, BUT a mapped drive can stay solidly mapped and accessible for days before balking.
 
Additionally, the mapped drives tend to "bake in" over time, and the users obviously stop complaining, and all my hoop-jumping seems to have been for nothing.  

-These are manually mapped drives, not group policy maps.
-All Windows Updates, Office updates and firmware/BIOS/chipset driver updates have been performed and are current.
-Power saving properties have been set to maximum wherever possible.

Very frustrating, luckily not mission critical, but I'd love to find a real solution and/or fix.  Happy to jump thru a few more hoops if we get on the right track.

thanks

I am neeing a way to redirect a local domain URL

https://server.text.text.text.47262393.loc/RDWeb
 to something a bit more easy for users to remember
like

https://remote.loc/RDWeb


everything is on our local network with no need for any access from the outside world.  Any help would be appreciated.

Thanks

A customer of mine has failed a PCI scan, mainly due to files stored on two bookkeeping computers, which contain sensitive data, like SSNs for employees, tax returns, and a small number of credit card numbers... Some of it is easy, old mailboxes, old emails, duplicate files, that can just be deleted.

Some of that data will need to be kept, though, possibly for long-term storage, but in a way that is PCI Compliant.

The credit card numbers are most likely internal, not customers - the business mainly transacts with their customers via checks, which are electronically deposited and then shredded when the accounts are reconciled.

What is the best/correct method to recommend to them for storing and accessing this data going forward that is both compliant and usable by not-very-technical bookkeeping staff?

They are a network of 10 total active users all running Windows 10 Pro, and joined to Active Directory via Windows Small Business Server 2011, and do have shared file access on the servers. For compliance, I'm thinking it would be best to have this data on the server, where it is assuredly backed up, and permissions are stricter, but does that create a more centralized potential point of failure?

Your advice and recommendations are appreciated!

I want to install a standalone Microsoft Certificate authority (ADCS) that is able to issue certificates to cisco devices. The network guys need a CA that supports  SCEP. We do not want to make any changes to the existing CA and want to build a temporary standalone CA for testing.
What additional steps are required to allow a Microsoft CA to issue IPsec certificates to network devices and support the SCEP protocol.

Is it enough to just install the sub component or does it need some configuration.

We have a very simple network (home router, few PCs and Mac, all running latest respective OSes) and for some reason when we share a Windows folder (for example C:\Network File Share) to the Macs we are able to see the folder inside of it (for example C:\Network File Share\Example) however we can not see the files in the folder.  We actually have to go in and share (example C:\Network File Share\Example) the folder to see the contents (files).  What are we doing wrong with file sharing to be able to see the folders but not the files?

I have a Mac connected to a network but can't get the "other user" account to pop up when u reboot or logout... I see it appear when I turn on the guest account and logout but it disappears after  few seconds ....I also tried manually setting the DNS and that was a no go ... I am able to ping the domain from Terminal. I have all the log in options set correctly but I just can't get that option does not populate to the screen.

I recently migrated 2 VMs to AWS EC2.
Both the new AWS VMs can ping  server1 (also AWS VM), but cannot connect to server1 in explorer.  All other workstations/servers in our domain can, including other AWS VMs that are on a different subnet.  (172.27.162,xxx is the subnet for the new VMs. Other AWS VMs on 172.27.130.xxx subnet connect fine).

When trying to navigate to the share, the following error occurs: "Windows cannot access \\server1\"  error code 0x80004005

Any ideas how this could be fixed?

I have a "File Server" Windows 7 Pro, (not a domain Server) that keeps everyone's files and documents.  This has worked fine for a couple years.  Suddenly for no apparent reason all files accessed over the LAN come up "Read Only".

The "File Server" is about 4 years old.  Could the Hard Disk Drive be failing?

Thanks fort any advice.

We have about 50 Dell Wyse 3040 Thin Clients and we have just installed the Wyse Management Suite to try to get a handle on what we have and also be able to standardize the versions with more ease. It looks like a great piece of software. I am used to 10Zig management where it will do a search on our network for all its devices so we can add them to the interface however I don't seem to be able to find anything in the software or the manual that offers such an option with the Wyse Management Suite.

Is there anyone familiar with loading currently running devices into a new install of the WMS? I don't see anything such as an import either except for importing from another software package.
Thanks in advance.

This is 100k sqaure feet, two storey, new manufacturing facility, on its stage of network/architect design.
We estimate that there will be 200 spots that need network access, for computers, VoIP phones, WiFi APs, smart TVs and security cameras.
In about 80 spots of the above, a VoIP phone and a PC will coexist.  These spots are the sitting spots or cubicles for engineers, managers and office staff.

The main question - should we run two network drops or one network drop in each of above 80 spots?
Option1: Two drops - One for VoIP phone, the other one for the computer.
Option2: One drop - VoIP phone and the computer will be daisy chained.

Not trying to over complicate the above main topic, we do have a few other questions as below in case you'd like to share some insights as well
1. Should we separate VoIP phones and computers into different VLANs? Why?
2. If we put VoIP phones on a separate VLAN, will the above Option2 still be doable?
3. Should we deploy CAT6A or CAT6 cables? 10G network is getting popular.
4. Should we run all cables directly from the end spots to the server room? Or, install some switches in the middle?
5. Any other thoughts? Or anything we should be aware of?

Thanks in advance!

I have a network that has been getting user reports that "the internet is slow".  Plenty of users....
I can see slowness in web browsing but:
- speed tests look fine
- DNS response times look fine
- internal and internet traffic levels look fine
- I've rebooted the main firewall and don't see any issues there - no recent changes.

I'm using PRTG for network monitoring and network traffic levels appear to be reasonable.

I rather suspect DNS issues but can't pinpoint any.

I'd really like to have a nice tool that would help with this.
And, suggestions about how to approach this would help.

Hi,

Good day.

I am looking for an usenet provider that offers a built in usenet client as part of the subscription. I am looking for usenet providers with monthly subscriptions and no contracts that offer a free usenet client.

Please reply to this post asap.

Thanks for your support.

Warm Regards,
Sriram.

This started when I inserted a hyperlink into an email.

The first time I inserted a hyperlink to a file in General drive there was only 1 General Drive. When I did another insert there were 9. (I did not insert 9 files)

This doesn't happen to others. What could be causing this?
