we have done an audit of our of our AD domains, and found several hundred empty AD groups (no members). Our admins don't seem particularly concerned about this, even though accepted its years worth of bad housekeeping. I am wondering if they have overlooked any risks in leaving the empty groups in place even though clearly serving no operational purposes to the business. Is there any risk in leaving masses of empty security groups in a domain, if so what?
My network included a NAS (N:), which crashed.  I recovered its data and installed another NAS which I want to name N: as well for convenience, and because many of my applications "look" for the N: designation.

I have found it impossible to get rid of N:.  It continues to "exist" on one of my computers which will not let me use the N: designation.
I have tried rebooting.  I have tried deleting the N: designation from my list of disks, but it keeps coming back, even though the computer will not let me "click" it.

Please someone help me get rid of this "ghost" N:

I have Windows Server 2012 and I've been planing to install DHCP server in Windows since I have DNS and Domain in that server, but my networks utilizes switch's DHCP and I am wondering what is the best practices to manage DHCP is it to use core switch's DHCP or Windows Server DHCP?
I have an MPLS network.  One site x.x.7.0 is over utilizing the bandwidth on the MPLS with INET traffic.

I have purchased another internet connection with a larger pipe that I want to offload all internet traffic for the location to.

I am trying to use static routes set up on each PC to accomplish this.  I have the MPLS gateway as x.x.7.1 I have the INET gateway set up as x.x.7.254.  I set up two static routes on each workstation.  I would like the default gateway to stay x.x.7.1 so as not to interfere with MPLS traffic.  These are the steps I have followed.

1. Set NIC on PC to x.x.7.10 mask, gateway x.x.7.1
2. open CMD as admin, route delete
3. add route mask x.x.7.254 -p
4. add route x.x.1.0 (mpls traffic) mask  x.x.7.1 -p

Step three blows out the default gateway on the NIC and nukes the MPLS traffic.  I just need to add the .254 route for Internet traffic while keeping the default gateway on the NIC x.x7.1
What am I missing?
Main PC...
I have about 4 other drives and folders on other pc's successfully mapped to this main pc...

Problem PC...
I have file and print sharing turned on...
I have shared the folder I want and "everyone" has full control...
I have a drive from my MAIN PC mapped to this Problem PC...
So mapping a drive IS WORKING one way only...

When I go to the Main PC and try to map the shared folder from the Problem PC...
The mapped folder does not appear in the Main PC...
File Explorer > Computer > Map Network Drive > Choose Drive Letter > Browse...the shared folder on the problem PC does NOT show up...however...2 other PC's that have shared drives DO show up...

So it seems to me the issue is in the Problem PC...something in sharing that did not happen...

All computers run out of the same switch from same router...I have NO subnets...
IP address are good...
All computers are in same workgroup...
All computers use the same account name and password...
All computers have file and print sharing turned ON...
All computers have "everyone" with full control permissions...
All computers run either Win 7 Pro or Win 10 Pro...

I  have been fighting this off an on for 2-3 days and I'm getting no where...

What am I missing...??????

Thanks in advance for any suggestions...
is there anyway to use get-acl to get the ACL for all sub folders in a directory. That is as far down the structure as I want it to report, not every file and other folders in the sub folders, but just one level - written to excel CSV? It would be great if it could also include the size of the sub folders as well in MB.
would there be any way technically to determine if 2 devices are using the same AD account to access network resources? And if so how could it be done? we have an added complication in that half the users don't have desktops/laptops and use thin client WYSE devices to access a citrix environment, so unsure if this adds to how realistic this may be to prove or not.
In an office I maintain, we have about 10 PC's running Windows 10. After a windows update, the clients are unable to resolve external host names. It appears this issue arose after the Fall Creators Update.

-The workstations are able to ping an external IP but they cannot ping an external host name (www.google.com), even when configured statically to use google DNS.

-Windows seems to leave with with no option to roll back the creators update.

-The warehouse PC is not on the domain, and has no issues even with all of the latest updates.

-After a reboot, the user's can browse the internet and outlook will connect to exchange for about 3 minutes before they go back to having the same issue

On the Client PC I've tried:

Malware scans and Windows Defenders Scans: They show my computer is not infected.
Completing remaining updates > no change
Flushing DNS > no change
IP Release/Renew and netsh int ip reset > no change
Noticed IPv6 was enabled, tried disabling it > no change
Changing to Google's public DNS  > no change
Reinstalling NIC driver > no change

I'm not really sure if this is an issue with the MS update on each machine or something on the domain that is not meshing. I was relieved that I still had the failure with the PC using google for DNS thinking my server is not at fault, however it bugs me that the non domain PC has no issues.

Where can I troubleshoot next?

Hi EE,

After restarting a website in IIS I get the following popup see attached

Now I am getting a 404 error when trying to access the website.

Any assistance is welcome.

Thank you.
About a month ago I reset our KRBTGT account using this script from Technet:


Everything verified and succeeded. Every since then like clockwork every Saturday almost our entire AD of User Accounts gets locked out. Computer Accounts are unaffected. I have checked and found a ton of event ID 4771's with the Failure Code 0x18 and 0x12. This is reflected in their meanings documented below:


They claim that pre-auth is failing and then causing the lockout. I've checked and a lot of our Kerberos tickets do expire on Saturday. In addition to the 4771's I also see a lot of 4768 events.


I've tried rebooting all clients, though not servers, to flush the existing tickets but that hasn't helped. Neither has bouncing the DC's or Restarting the Ticket Granting service. I've even played with some powershell scripts to use klist to flush the tickets for all users. Though I haven't gotten them to work remotely.

Still this has been going on for over a month and I can't find anyone else having a similar issue. Resetting the KRBTGT account should NOT cause this to happen from everything I've read. We are at 2012 R2 Functional for our Forest and Domain level. When going up a level in the past we never had a similar issue. It was …
We are expanding the internet access to the entire school body and we will need 800+ ip addresses to accommodate them all. the existing DHCP range is with a Mask of the default Gateway is at if i open the mask to it moves it to a class B network, so does that mean i have to change my existing ip address range from 192.168.x.x to a class B range? If i set the range from to using subnet mask of I will have to move the Default Gateway from to something outside the range. i tried to start the rang at to keep the DFGW at but i get an error saying the gateway is not on the correct subnet? Is there a better way to do this?

Thank you
I have an ISA 2004 server with three legs. (Actually four, but one is unused). I'm trying to connect to a perimeter network through another router on an adapter I've called "Perimeter2".  The perimeter2 network card has the address, and the third party router have on the inside.
The remote networks have 192.168.x.0 and 192.168.y.0 where x and y are segment addresses not present locally.
I have defined all three of the above networks in the Perimeter2 network definition.
Network rules for Perimeter 2 are "Route" with "internal", Perimeter2", and "VPN-clients" in both source and destination networks.
In addition I've added two persistent routes to the networks 192.168.x.0, and 192.168.y.0 in windows.
I have a firewall policy which allows All outbound between all networks (Internal, localhost and perimeter2"

I can ping and all machines on the perimeter networks (x and y) from the ISA server locally, but from any machine on the LAN I can only ping,  the network adapter on the ISA itself.

Please advice.
Dear Experts, how can we schedule a task which will be executed in future on WinServer 2012R2?

For example:

On 1/1/2020; create a GPO to change background of domain users' PCs

Does Anyone have experience?
I have a client with whom I've set up a home group. He's got 3 computers with each having Windows 7 installed. Every evening he leaves his shop, every morning when he comes in, his computers and two HP printers have lost their connectivity. The home group eventually regains its settings, but he has to setup his printers from scratch. He changed routers recently. Before his router change, his network had no problems.
I have a Windows 10 PC with a PCI NIC card w/4 POE ports. I am looking for software that can manage those 4 ports as a switch. Currently, the IP surveillance cameras that I have plugged in can communicate to the Windows box, but don't have the ability to route. Any help is much appreciated!!!
for a small business which conference system will you recommend?

what are the leading brands out there?

I am sure this is a dummy question but i suck in networking.

What is the purpose of a windows server box to have multiple ID addresses assigned to it, although they share the same host-name on DNS?

Points of My Scenario
1. I am admin of a Reporting Services (2008 R2) website that has been working until this morning.
2. Issue: users are now unable to authenticate/access it by its FQDN (fully qualified domain name) - it keeps prompting for credentials
3. When users type IP address instead of the FQDN, they can access the website

QUESTION: How can I resolve this issue so that users can once again access it via the FQDN?
How can I block people from accessing my machine via file explorer(C:\\machine name)
people in my network should not be able to access my Files or C drive the RDP or file explorer both should be disalbed

and if someone tries to ping my machine the ping should not send any packets.

How can i do it.
