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

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.
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 …
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 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?

Thanks 4 your help,
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.
I'm troubleshooting a slow connection to my home office.

Pinging the domain controller returns 92 ms.

Is this too high?  What is the normal return in ms?

I am connected to the home office via MPLS circuit.
I had this question after viewing Destination host is unreachable while bing.
On a Windows Server 2012 R2 How do I enable all firewalls outbound so all outbound traffic is allowed?
We have a Windows share drive that only certain PCS can access the other PCS GET ACCESS Denied even though they are in same AD Group. The AD Group is computer BASED not  User based. Again all PCs get the mapping and a few computers can access the drive but not all of them. The PCs that are getting access denied are generic accounts that autologin. Any Ideas

Hi Support
we have 2 site in AD DS (HO & AWS), i have installed a new DC for AWS Site and associated the AWS subnet
now the machines in my AWS Site are logon to HO DC instead of AWS DC, this increase network latency (as 2 sites are connected through site to site VPN). how can we make sure AWS site clients authenticate AWS DC
I added some capacity to both virtual hard disks of the only 2012 R2 guest running on the 2012 R2 host. Disk capacity was added to the guest, and I expanded both drives on the guest. All seemed good.

Little while later I received a message that the replication was critical. The 1st event ID was 33680, which only said the replication failed. This was followed immediately by IDs 32086 and 32422.

32422 said:
Hyper-V Replica failed to apply the log file onto the VHD for virtual machine 'xxx-Svr1'. (Virtual machine ID 05EB0EC0-E24E-4F3E-9AB8-CC005C78634D). An out-of-bounds write was encountered on the Replica virtual machine. The primary server VHD might have been resized. Ensure that the disk sizes of the Primary and Replica virtual machines are the same.

Oh crap...didn't realize I had to also resize the disks on the replica, too! Sigh...

https://blogs.technet.microsoft.com/virtualization/2013/11/14/online-resize-of-virtual-disks-attached-to-replicating-virtual-machines/ said to resize the disks on the replica, then resume replication.

Did all that...to no avail!

Restarting the host and the replication servers didn't resolve the problem. Yikes!

What should I try next?



I have a contractor managing a product that needs read only access to a single (user account) OU.  I do not want them to see anything else in my active directory but items in that specific OU, whether they are using an LDAP product or anything else.  

Would it be possible to create a read-only user account that can only see items in this OU?  If so, how?  

Thank you!!
So I have an old sonicwall I am replacing with a fortigate.  The PC's have 7 day DHCP leases... The Fortigate will be set up to be the same IP as the sonicwall was and it will have the same DHCP range... But of course when I make the swap the fortigates lease list will be empty... Im curious - as PC's check in with the firewall, will they keep their addresses?  Or will they wind up getting reset the lowest available address at the time?

Any other concerns to think about with swapping the firewalls?

Hello All, I hope this isn't too easy or a repetitive question. One weak area I have is understanding how to configure DNS on a domain controller -the only DC on a network. It has the AD and DNS and we made it the DHCP server. OS is 2012r2. Let me explain what configurations I have on the server and router...  We have a static IP address on a SonicWALL router, configured with the ISP DNS servers. Now - here's one possible fault... I have teamed the NICs on the server (2), just the standard options.... I think I have read somewhere that may not be a good idea on a DNS server... not sure... So the teamed NICs have the servers IP address on the LAN assigned. I have server set up to use root hint servers and no forwarders and the root hint servers are resolving. I am using the ISP primary DNS as preferred DNS server on the DC NIC (teamed), for the secondary I am using the DC's LAN IP address - versus the loopback address...  I am away from the site at the moment but will go onsite soon. I have read a lot of stuff lately and its pretty diverse... meaning different opinions for similar circumstances others have had. Do I need to get rid of the ISP's DNS server in the DC LAN properties altogether? Using root hints, if it matters to next question, what would  use for the Primary and Secondary DNS servers in the DC's NIC properties then? I have read - use the DC's IP address as the first (primary).... I just need an answer I can feel good about - and I will wait to be at the server …
A few days ago my Netgear router stopped working. So, I purchased a new one. It is the Netgear WNDR3400v3. My laptop is hardwired to the router. After setting everything up and running a speed test, I noticed that the download speed was only 70 Mb per second. Typically I get over 100 Mb per second.

My router is connected to a cable modem which was provided by my ISP (Spectrum). If I connect my laptop directly to the modem, the download speed exceeds 100 Mb per second.

I've seen information on the Internet suggesting that my router does not support download speeds that high. Netgear recommended changing the MTU. That didn't work. Yet another post I read recommended disabling IPv6. I haven't figured out how to do that on my router.

The fact that I can get full download speeds when connected directly to the modem implies that the router is the problem. I have opened a support ticket with Netgear, but I was just wondering whether anyone in the Experts community had any ideas.
We have a headquarters and two branch offices. The branch officers are connected to the main officer with MPLS. Here's the configuration:
1. main office:
2. branch office 1:
3. branch office 2:

In the main office, the DHCP is almost full. What's the better way to add more IP addresses in the main office? with Superscope?
how many hosts can we include? is it unlimited?
looking for some sort of checklist or ideas in terms of criteria in which to critically appraise the performance of our IT service, which is partially in house and certain functions outsourced. I know there are obvious areas such as time to resolve incidents/service requests, uptime of critical apps etc. But was hoping if you work in a contract monitoring type role where you outsource certain IT functions if you have any criteria in which you audit/assess the relevant team against.
