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.

I have new Windows 2012 R2 NPS member server that was setup for the purpose of Wireless Authentication via RADIUS.  
I have successfully connect when logged into the computer and the Windows Groups that are allowed are Domain Users or Domain Computers.  If I remove the Domain Users group from the NPS Policy and only have the Domain Computer I am not able to authenticate and I get event id 5632 on the client computer.

EAP Root Cause String : Network authentication failed due to a problem with the user account.

This is a trusted computer (At least I think so).  I am not sure why it cannot authenticate

I am trying to migrate off of Lync server 2010 to Skype for Business server 2015.  I have created a new server have patched the server all the way with the windows updates and then started my Skype for Business install.  I was running through the Skype for Business Server 2015 Deployment Wizard.  I have already prepared AD with no issues and then moved onto Install or Update Skype for Business Server System.  However it did not detect one of the prerequisites which is KB2982006.  I have tried installing it and I keep getting "The update is not applicable to your computer"  I have tried installing all of the prerequisites for this file but cannot install one prerequisites that it needs which is KB2919442.  It gives me the same error.  I have done a sfc /scannow with no errors, tried windows update troubleshooter with no luck.  Any suggestions.

I've got a share in 2012r2 Standard that we can save to the main folder but if we try to save to any child folders we get 'Out of Disk Space Error'.

I've confirmed that the 'Replace all child object permission entries with inheritable permission entries from this object' is checked

Other that a quota which is not set I'm not sure what would cause this. Does anyone have any ideas?

Now starting to test Windows 2012 Server.  Everthing is working well but we need to change to port 82 rather than 3389 when launching applications.

I ran this command
Set-RDSessionCollectionConfiguration –CollectionName QuickSessionCollection –CustomRdpProperty “server port:i:82”

Open in new window


Now that the port has been changed, I get this error.  

RDS Error
An thoughts as to the cause?
- Windows Firewall is off
- Server has been restarted(just in case anyone asks)

Hey guys. I need some help for... a friend. (It's a Monday. Please don't ask)

Environment:
2 Domain controllers running Server 2012 Datacenter
Veeam BR 9 on Server 2012 Datacenter

Leadup to issue
DHCP scope was acting funny... a few tinkerings later and the entire service was hosed. A restore of that DC on Veeam and now the entire sync between both DCs was not working, even after attempts to get them synced (dcdiag, repadmin, etc.).

A restore of both DCs to the same backup time should work, right? NO. Veeam restores DCs into non-authoritative mode...

Current situation:
DC1 is restored from Friday night's backup but shut down for now. Attempts to log in with DSRM password failed. (Just great, right?)

DC2 is running and serving DNS, AD, etc. but it fails dcdiag tests:
-time server advertising
-DFSREvent
-KnowsOfRoleHolders
-Replication attempts (obv.)
-RidManager
- etc (too many to list)

Question/Request:
Before my uhhh... friend breaks anything else, just throw me in the right direction. He's a little out of sorts and just needs to be reminded what to do at this point.
I would tell him to do a non-authoritative restore of DC1 and let DC2 be "the boss", but both servers were restored from Veeam in non-authoritative mode and the DSRM password isn't working. Attempts on DC2 to change the password failed. Yaaay!

Within the https://social.technet.microsoft.com/wiki/contents/articles/24541.powershell-bulk-create-ad-users-from-csv-file.aspx#Code_Used webpage which contains instructions on creating a CSV spreadsheet that contains fields such as the user's firstname, lastname, maildomain, etc. what should be entered within the SAM spreadsheet column?

I understand what all of fields need except for the SAM field. What should be entered within the SAM field?

Firstname | Lastname | Maildomain | SAM | OU | Password | Description

User | Test01 | contoso.com | utest01 | OU=Standard Users,OU=Users,DC=domain,DC=loc | P@ssw0rd| Test User

One of the lines of code explains the syntax as " New-ADUser -Name "$Displayname" -DisplayName "$Displayname" -SamAccountName $SAM -UserPrincipalName $UPN -GivenName "$UserFirstname" -Surname "$UserLastname" -Description "$Description" -AccountPassword (ConvertTo-SecureString $Password -AsPlainText -Force) -Enabled $true -Path "$OU" -ChangePasswordAtLogon $false –PasswordNeverExpires $true -server domain"

Please provide me with the correct entry that should be used for SAM.

Dear Experts, as my understanding, Exchange DAG (for 2 nodes) is the cluster that replicate all data from Mail Server1 to Mail Server2. Is it still correct in SAN storage environment? If so, everything related to mail in SAN storage will be duplicated, am I right? Can we configure so that there is only one version of data exists on it and there are only 2 VM servers for HA-failover?

Many thanks as always!

My "server1" Windows 2012 R2 has two NICs, with two static IPs, 192.168.20.10 and 192.168.37.10

When ping  "server1" from a client on the 192.168.20.x it replies with the 192.168.37.10 IP and says it cannot find it

How can I get "server1" to reply as 192.168.20.10 instead ?

We have a large AD environment with 10k devices and have ADCS setup. Earlier in the week we had and issue were devices started to fail to connect the network . After further review we found the CDP location on our root CA which is in a workgroup and one of our SubCA's CDP location changed to something like: ldap://myLDAPServer....What makes this even more odd is the fact we have one other SubCA that does not have anything published to it yet its CDP location was fine.  There was noting in the logs and stumped as to the root cause. I have been dealing with CA servers for the past 10 years on and off and have never seen this before.

Any thoughts???

I'm sure this is something simple I've missed but I built a new DC. I enabled Remote Desktop Connections in server manager and I'm unable to get a connection to it. The RDP windows times out before it even sees the DC using FQDN or IP address.

RDP to the new DC was working when my old DC was running so I assumed this was a DNS issue (which would mean RDP to IP would work but it does not).

Any suggestions?

Thanks,
David

Win10 clients previously had GPO applied that made them update using a local WSUS Server, the GPO has now been removed, how do I make those clients update via windows update again? Using GPO preferably.

I have found a strange performance issue with xBase++.
Essentially, client performance is very good until database files in the same database are opened locally on the server (see graph.)
Details are below.
Thanks,
Tim

Test Setup
----------------
•      Three client platforms and two server platforms, all under controlled conditions.
•      Clients: Win7 10/100, Win7 gb, Win Server 2008 R2 via XenApp
•      Servers: Win Server 2012 R2, Win Server 2008 R2 (VMware virtual machine)
•      xBase++: 2.00.785
•      Dbe: FOXCDX (see dbesys.prg example)
•      Client test function: representative function that creates a DBF/CDX file on the client C: drive from data assembled from multiple open data files residing on the server.

Test Procedure
----------------------
1.      Reboot the server
2.      On a client map a drive to the server database share
3.      Run the app from the client c: drive, starting it in the mapped server folder – performance is good for multiple simultaneous clients
4.      Run an app locally on the server and open files in the same database folder as the client
5.      As the number of files opened locally on the server increases the client performance degrades significantly for all clients, even new instances on different machines (see graph)
6.      Close the locally opened files on the server
7.      Client performance remains degraded

Notes
---------
•      The performance is poor for all subsequent clients once a database folder has files opened locally on the server
•      The performance …

Hi,
 
I like to upgrade a virtual machine running Windows 2008 R2 to Windows 2012 R2 in Hyper-V environment.

If this is a standalone computer, I would simply insert Windows 2012 R2 DVD and start upgrade process.
In virtual environment, do I simply replace Windows2008R2.iso with Windows2012R2.iso and start the VM?
Is there more to it?

Thanks.
