Windows Server 2012





Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

We are facing very difficult situation at the moment. let me explain in detail.

Problem 1:
We are running Exchange 2016 server and  Domain controller AD on two separate VM's.
Last night, we faced disaster and our Hyper V HDD was crash. We trying everything but its totally crash.
We have Exchange 2016 VM backup but we don't have AD VM backup.
Please let me know how what will I do at this situation. If I created new AD with same domain name so I believe I need to rejoin exchange server with new AD.
What will happen with current mailboxes. They will work like same way that they were working previously.

Problem 2:
As i explain above our Hyper V HDD was crash so our three RDSH servers and their AD (Its not same AD as i explain above, different domain name) also down.
Again we have RDSH servers backup but we don't have AD backup so i guess I have to republish all the apps again.

Please let me know how to resolve these problems. Both are related to AD's. One for Exchange 2016 and other for RDSH server.

OS: Windows server 2016
Exchange: Exchange server is 2016

CEOs need to know what they should worry about

Nearly every week during the past few years has featured a headline about the latest data breach, malware attack, ransomware demand, or unrecoverable corporate data loss. Those stories are frequently followed by news that the CEOs at those companies were forced to resign.


I am trying to expand a volume on a cluster of Windows 2016 VM's. The cluster contains 2 nodes and they are all running on top of vSphere. When I try to expand a hard disk in vSphere I receive the message below from the vcenter console:

The disk extend operation failed: The virtual disk requires a feature not supported by this program
Hot-extend is currently supported only for VMFS flat virtual disks without snapshots opened in persistent mode.

I also tried shutting down the Node1(active) and then expanding the vm disk. However, I receive a message stating there is a locked file:

The disk extend operation failed: Failed to lock the file

Although, this could be due to the clustered aspect of it. Can someone help me clear my webs and tell me if I am not following the proper procedures or if I am actually experiencing an issue within vmware while trying to expand the disk?

I am simply trying to expand the vmdk in vsphere and then go into the windows server and expand it using diskmgmt

Thank you
Currently I have a 2012R2 storage spaces pool of  4 x 1TB HDDs in a two-way mirror, no tier. If I need more space, can I just add one more, yes just one more 1TB HDD and hope it will increase half TB of free space?
Looking for some help concerning the RDS Gateway Role and load balancing.

I have an pre-production RDS environment that contains 3x Gateway Servers. I have tested the environment by connecting through each one of the individual Gateways and everything works just fine.

I'm now at the point where I want to use my hardware load balancer to receive the connections and distribute them between the 3 Gateways. I would also like to use the UDP Transport on 3391 as well.

The part that I don't completely understand is that I'm assuming that each individual connection, which will be coming in initially on TCP 443 and then UDP 3391 would need to be routed to the same gateway?

It would make sense and be easy to set the LB up to balance both ports to the 3 Gateways, but without any specific load balancer magic, connection "A" might go to one gateway for 443 and a different gateway for 3391.

It's possible that I could be overthinking this and I'm not sure if this is a flat out requirement. In the case where the user initially connects on Port 443 to Gateway A, then the UDP traffic comes in and the LB forwards that to Gateway B. Does Gateway B know to forward that UDP traffic to Gateway A if all the gateways have the farm properties configured?

These are the things that I don't really know.
My coworker and I are at odds on the correct way to upgrade our DC.

What I've learned, but never had to promote a new DC, was to use DCPROMO. To promote the new server and then demote the old server.

I would like to install windows server 2012 r2 add it to the domain and promote via dcpromo.exe.

He's been at the company longer(10+ years, I've been here for 2 months) and thinks it's better if we use his way. We use a Datto for snapshot backups of the server. He thinks it's best to do a bare metal restore from the Datto to the server. We are also in a fail over clustered environment if that makes a difference.

The server is a Gen 3 HP from 2010. The new server is a gen10 from 2019. I told him that it's too great of a time period between servers that a fresh install is best. He says that our DFRS, DNS, DHCP won't be transferred over to the new DC. I've told him that EVERYTHING is transferred over with DCPROMO.

I spoke with the Director and he says we need to figure this out, laughed and walked away.
Now, this isn't going anywhere, so I'd like to get some feedback from seasoned system administrators.

Thank you,
Hi, we are looking to decommission our old DFS file server (FS1). FS1 was the original file server where we setup the DFS and replicated to FS2 and FS3. We had all three servers replicating the correctly for the past few months. Now we have decided it’s time to decommission FS1. We shutdown FS1 to see if the everything would still function. With FS1 offline, FS2 and FS3 are still replicating without issue.  

Can you tell me the correct way to permanently decommission FS1 without effecting the DFS namespace and replication? When I open DFS Management on FS2 I see an error on our namespace. “The namespace cannot be queried. The specified domain either does not exist or could not be connected”.

Environment: 3 File servers, 1 namespace, 3 replications
FS1 – Server 2008 R2 (Need to decommission but original creator of DFS namespace)
FS2 – Server 2012
FS3 – Server 2012

1 Namespace

3 Replications
Issue in Brief: Unable to add node back to the cluster.

Details of the issue: We noticed that one of the nodes in the two node cluster(node & disk majority) is 'down' in FCM.  However, we're able to ping it from another node and also RDP into it.

Troubleshooting Performed:
-Tried to evict and re-add the problematic node to the cluster, but unsuccessful in doing so - both via. PowerShell and via. GUI.
-Also rebooted the node, and performed the above operation.  Still no luck.
  Error: Unable to successfully cleanup.
-Applied "Clear-ClusterNode" and it was successful.
-Then, tried to re-add the node but received the same error, but through GUI & PowerShell.
-Rebooted the problematic node; still getting the same error.
-Upon further investigation, we noticed that  the "CLUSDB" was missing in the registry of the problematic node.
-Copied the database to the problematic node (from the other node), and tried to load it in the registry, without success.
-Then copied the "CLUSDB.blf" file to the location, renamed it to "CLUSDB" and tried to add the node again.  Still getting the same error.

-Looked into AD, and found the appropriate CNO for the cluster, and VCOs of its corresponding nodes.

-Noticed below error in the cluster logs as part of our investigation.

"New join with n2: stage: 'Authenticate Initial Connection' status HrError(0x80090301) reason: '[SV] Authentication failed'"

-Did a "portquery" on the other node, from the problematic node and it …
Need to install SAP Cristal  Reports veiwer on about 50 computers. I have a domain but they don't have an msi file option. Our users don't have local admin rights to install the software otherwise , I could ask them to do it. Anyway that I can push this somehow without an msi file. We have 2012 domain controlers.
I manage an active directory domain at the Windows Server 2012 Domain and Forest functional levels with two replicating DCs.  This domain was first created as a 2000 AD domain, and then migrated to Windows Server 2003, then migrated to Windows Server 2008 R2, and then again to Windows Server 2012.  So the AD domain has been active for about 20 years now, and I am concerned the domain may now have a lot of extra baggage that is no longer needed or even applies.  Our environment has also hosted Exchange NT Server, Exchange Server 2003, and now an Exchange 2010 server.  We plan on moving to O365 as well. I do not plan on O365 mailboxes integrated/managed by AD.  We are looking at no more than 20 mailboxes.

I also believe AD now employs more secure channels of replication that needs to be manually applied, and was not automatically applied during the 2012 AD level migration.

Later this year, I will purchase a new Windows Server 2019 server that will host a new DC. My understanding employing a new 2019 server as a domain controller only allows functional levels at 2016 domain and forest functional levels, so there is no 2019 domain/functional level option.  

So I have two options:

I have the choice of migrating the existing AD domain again to the 2016 functional levels once again of which is pretty easy and not much fuss.

Or, I can go ahead and setup a brand new 2016 AD domain/forest with a 2016 Server as a replicated DC, and 2019 server functioning as the primary …
Hi All

We are experiencing BSOD crashes within our Windows 2012R2 RDS environment. This is happening most days but is not consistent to 1 RDS server.

Background info:

9 Windows 2012r2 RDS servers in a farm using Microsoft RD Connection Broker
User profiles are UPD's hosted on a solid state SAN

The RDS servers are virtual and are hosted on a 2012r2 HyperV cluster with Failover Cluster Manager and System Center 2012R2 Virtual Machine Manager. All Virtual servers are provided by a Cluster of Dell Equallogic and Compellent SANS

No other VM's are blue screening within the HyperV cluster only the RDS servers which is now almost daily.

Prior to the crash the RDS server logs the following:

The description for Event ID 56 from source Application Popup cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:


the message resource is present but the message is not found in the string/message table


A fatal alert was received from the remote endpoint. The TLS protocol defined fatal alert code is 49.

Other than that the logs don't report much apart from the standard "The previous system shutdown was unexpected"

got a server 2012- and got iis version 8

checked the binding - type " http"  and  ip address   "all unassigned" and port "8080"

got a site in my iis. from my server - i can access the site using:  http://localhost:8080/server - it works
but could not access it with ip address from my server or anyother computer which is same network : - not working.

i tried telnet using localhost to 8080 - works
telnet using ip address to 8080- failed.

any help guys to make my ip address work for iis ??
checked the firewall in server- it comes as some settings are controlled by gpo. but still it shows, domain profile/private profile/public profile -all are turned off.
I have 4 x 1TB Storage Spaces (2-way mirror, hot-swappable, no more spare swappable slot available) on a 2012R2 server. One of the hard drives appears to be failed in Smart alert even the drive still shows healthy on the OS. After already identified the potentially failed drive and felt ready to replace the failed drive, I became so confused about how to while reading through articles on the net. Some said I need to insert a new drive in before doing anything but I don't have any empty slot available. Can you shed some light on this please?

Also, I understand in Win10, there is a "Prepare for removal"/"Ready to remove" option to remove a drive from an SS without the need of issuing any PS commands. Thus, I'm wondering if I can just select "Remove" the failed physical drive from Storage Pools/Physical Disks list on GUI and then physically replace the failed with a good one. Then add that new good drive back to the pool. Will that work?
We have a Cisco UCS with service profiles configured to boot from an iSCSI NetApp LUN.  The OS is 2012 R2 and is currently running on a B200 M3 server.  I am trying to migrate this windows OS to a B200 M4 blade but it continues to BSOD everytime it loads even in safe mode.

We updated the 1240/1340 vic driver to and i've updated the firmware to 3.2.3e as well.  We've adjusted the boot policy to boot the iscsi nic first but nothing appears to work.

Does anybody have any suggestions?
Hi, we have printers spread out across multiple sites, some are connected via VPN, and some are not. We have been using HP E-Print to print on the fly from any device, but it's been unreliable.

I essentially want to be able to print to any printer from any device/any time. What is the best way to accomplish?
Hi All,

i am trying to get a 2012 server to use two ranges of IP's in the same DHCP scope, i have changed the Subnet Mask to and the two ranges i'm tryign to use is -  it worked fine and handed out addresses, but i wanted to test it as if all the addresses were used up, so i excluded them out of the range but then  when i plug my laptop onto the network of the server it doesn't give me an IP address.  i would have thought it would just give me an IP of  but it hasn't and if it has then the default gateway is blank.

any suggestions?
Dear Experts, in Linux we have wondershaper tool to shape the network traffic.

Do we have another tool with the same function in Windows server 2012 environment?

We also would like to drop some traffic when its network bandwidth is higher than predefined rate. Can you please suggest?

Many thanks in advance!
Dear Experts, I'm installing Snort in an Exchange server but got this fatal error when loading the snort.conf file.

Can you please check and suggest?  How can I fix this directory? Many thanks!

Dear Experts, which ports do we need to open in an Exchange servers?

Attachment is the results of "netstat -aon" commands in our servers. Can you check and suggest some abnormal ports?

Many thanks in advance!
Hi, i have a 2012 R2 RDS Server, and on the printers, even though i change the printing defaults under my admin account, when users login, they are not seeing my settings. How can i change that?

We have a 2012 R2 RDS farm created by someone that left the company and wrote nothing down. i have created a new RDS farm similar to our existing one, with published apps and everything. However, our current farm he created has a published app that is actually the link to our rds host servers - select that "published app" and it takes you to a desktop selected from our load-balanced RDS servers. <pic of link is attached>

This is NOT in the published apps portion of that collection on the broker. This is being configured somewhere else. I assume in a config file on the web server? How can i recreate that for the new Farm?  I cannot use a regular published app mstsc because it needs to be load balanced between multiple servers, you don't get that option in a regular published app and that's NOT how it's configured currently in our production farm. There is no entry in a GPO to do this other than to say "load balance the servers". How can i create that so users can select it and be placed into a rdp load balanced desktop between host servers?  I can't find a walkthrough on line to do this. Please help.

Got a server in cloud(terminal server- 2012)
Got clients computers locally. And printers in same subnet as local computers
- connecting to cloud computer using wanip from local computer. Printer is added to local computer and rdp printer is selected.
Printer appearing in cloud computer. But even if I make my printer settings in local computer to blacknwhite- it doesn’t carry over to cloud.
Even if I change the redirected printer in cloud to blacknwhite, after log off and login to server again brings cloud option.

Any help to make blacknwhite option to carry over to cloud ?
