I need some help deconfiguring a DHCP failover

I have two domain controllers (dc01 and dc02) dhcp failover is configured as hot spare and has been working well for a long time.The scopes are replicated from dc01 to dc02. If dc01 goes down dc02 takes over.

But, I need to expand a scope. First I need to delete the existing scope since I have to change the subnet mask. When I try to delete I receive the error: Scope is part of a failover relationship. Please delete the scope from the relationship. When I try to deconfigure failover I get the following errors: check status of the failover relationship - failed, the dhcp server service is not running on the target computer, deconfigure failover failed error 1722 the dhcp server service is not running on the target computer.

I've found several posts about running this cmd in powershell: Remove-DhcpServerv4Failover -ComputerName...

Audit Policy in Windows Network

I couldn't find a good answer for this one, so I figured that I'd ask here. I'm working on setting up GPOs to do some auditing (specifically focused on logon/logoff events) in a Windows network. I've read various guides that talk about configuring audit settings in the Default Domain Policy and the Default Domain Controller Policy. It seems like general auditing is set up in the Default Domain Policy, whereas the Advanced Audit Policy Configuration settings are in the Default Domain Controller Policy. Is that the case? I would like to audit the event logs on workstations as well as DCs, so should I be configuring these settings in the Default Domain Policy GPO? Any insight, as well as examples of auditing configurations, are welcome. Thanks!

Sysvol and netlogon folder missing on my new 2012 R2 domain (replacing old 2003)

Folks,

We are replacing an old windows 2003 x86 server for a windows 2012 R2 64bit, we were able to add the new server to the forest, domain and promote it to domain controller and move the FSMO roles.

The issue now is that on the new server We don't see the SYSVOL or NETLOGON folders shares, We are able to replicate from both server no issue, on the even viewer on the old server we are getting error ID: 13559, and on the new server i notice that i was getting error ID: 6012 for schema update. (after that it showing the replication with no issue)

What is the best way that we can have the 2012 server ok with the folder, i was thinking to do a "Burflags d2 d4" to authoritative restore the folder and them take the 2003 out of the network with DCPROMO. or go the way some folks saying to upgrade the server 2003 to R2 them upgrade the Forrest?

Hi,
I have a Supermicro with IPMI and I want to sync the users from my Domain Controller (win2019) to it.
But I can't figure out how to do it.

I want all of the users in the group BEH IPMI to have access to IPMI.
I have created a user ipmi in my AD that are having all the nessesery access for LDAP.

But even that I have written the right settings I think, it don't work - do I miss something?
And where inside IPMI do I specify the group?

Replaced client's SBS 2011 domain controller+exchange with a 2016 DC and Office365 mailboxes. Everything went great except there are 3-4 users that have drive map issues after countless gpupdate/force and other resolution attempts. GPO for drive mapping started as Replace, after a week or two I changed it to Update.

3 of them have no mapped drives when they log in in the morning. 1 of them has all mapped drives, but one keeps reverting back to the old network path and that sbs 2011 box has long been removed from the network. I have to net use delete that drive and remap it, then it's fine all week, then on Monday morning it's...

Server in question is running Server 2008 R2 SP1

So, I'm trying to remove a role from one of our servers as the role is no longer needed but the server was originally configured a long time ago (over half a decade) and it hasn't really been maintained past that until now. When I try to run a refresh on Server Manager roles, I get the following error message:

Text

I can't find any documentation on this error online except for a 10 year old post on Microsoft Technet that deosn't apply to 2008 R2. When I look at Windows Logs, I see this:

Hi All,

We have few critical application servers which are in isolated network (Work group) and no access to the internet.

As there in no NTP the servers time is not accurate and its causing application to generate wrong timings.

How do i configure NTP for these servers with out joining to domain or connecting them to NTP.

Please advice on multiple options to work around this.

Thanks in advance.

A lot of people are creating windows 10 reference image using MDT from a virtual machine then deploy this image to physical hardware. My question is, after you have deployed this image to the physical machines, you have to install the drivers manually? How do you ensure the drivers get installed?

smigdeploy and Certificate Services

While studying for my MCSA 2016, I have been introduced to smigdeploy. As luck would have it, I have an opportunity to try it out on a project at the same time. A client of ours has a root CA running on 2003 and an issuing CA on 2008R2. Since 2003 can't generate SHA2-flavored certs, they need to upgrade their certificate chain to a version of Server that can.

The initial response by my team was to build a separate CA chain using 2016 and then when the certs begin to flow and everything looks to be okay, cut the old chain out. However, I think I might be able to use smig to move the roles from the old servers to new ones, allowing Certificate Services to recall and re-issue certs using stronger encryption. But I have a few questions for anyone who has experience with smig.

1) Does 2016 smig still support moving from 2003?

2) Does smig even...

Server 2012 (Hyper-V host) upgrade experience?

So I have a 2012 server that is a host for 2 hyper-v machines that needs to be upgraded.

I have procured the licenses for 2012r2 and 2016.

The 2 vm's on the server are a 2008r2 that is the PDC 

and a 2012 that is the Kaspersky AV server and MySql server.

The host is also the Veeam B&R server for the vm's.

Just wondering if anyone has an "hey look out for this" stuff to mention. I do have a physical BDC running just in case.  Once the host is upgraded i want to upgrade the vm's to 2016 as well.  Thoughts/suggestions welcome.  :)

Securing Development in Windows Server 2016

You can improve the security of your application development infrastructure by reducing the size and scope of application and compute resources. One way to do this is to containerize workloads. Windows Server and Microsoft Hyper-V containers enable you to isolate workloads from each other and the OS. Even if a container is compromised by an attacker, it will be difficult for the attacker to access the host OS. Containers also provide a standardized environment for development, test and production teams.

Containers
Containers provide an isolated and portable operating environment for apps. From the app’s perspective, a container appears to be a complete, isolated Windows OS with its own file system, devices and configuration. Therefore, in many respects, containers are like VMs because they run an OS, they support a file system, and you...

VPN Users Locked Out After Password Expires

Hi Everyone,

I have an age-old problem.  We have a domain-joined laptops for roaming users who are barely in the office.  Their password expires and when it does, they can't VPN in because the VPN uses AD to authenticate.  We use the WatchGuard VPN client and it doesn't have the ability to talk to Active Directory and change expired passwords.  The only way the user can get back in is if they call IT and get their password reset.

  • How are you guys dealing with this issue?  Do you use a VPN client that can address this situation?
  • I understand Microsoft's Routing and Remote Access & VPN client can resolve this issue.  Any bad thoughts towards Routing and Remote Access?

Thanks for your input.
