I help out a charity that has a Windows server 2012 R2 running as Essentials. Exchange is done by office 365.  Twice now, they are loosing access to the server and internet (as the DNS server for the machines on the LAN) after a few days.  A reboot cures everything.  I have an RMM agent on the server and both times, the server last checks into the RMM tool around 4AM.

Wondering how to troubleshoot that.

Some background:

Recently, there was a lightning strike nearby. Fried the key card door entry system, alarm system, phone system along with some of the computer network

Side note / question: the other systems were OLD... electronics are more susceptible to surges as they age, right?  caps dry out, etc.  A surge that might have not affected a newer machine could cause more harm to an older system?

Anyway, it blew out the main 16 port switch in the telco closet.  Getting that replaced.  Blew out a couple older data switches in a couple offices (using a single data line to that office to put the printer and PC on the internet), blew out a PC and monitor in another office.

The server appeared to be OK... but we're starting to see that need to reboot it.  twice now, they lose access to the server from the machines on the LAN.

Sitting at the server, I can ping it's own IP address.  Can't ping any other IP addresses.  From other machines, can ping other machines and the router.  I can do most anything - browse files on the server, check event logs, open apps. …

Dear Team, we grant permissions on Active Directory 2012 folders but seems like it did not correct.

We'd like to have this schema:

- User1(duypvn) and User2( are members of group IT
- User1 can Delete (Modify), Read, Write subfolders and files inside folder IT (#1)
- User2 can only Read and Write subfolders and files inside folder IT (#2)

We did these settings but could satisfy only #1
We got this error when testing #2. User2 COULD create NewFolder, New Files but COULD NOT rename them although it had Write permission

Is there any way which an user can read/write/modify folders/file but CANNOT delete them? Can you please suggest? Many thanks!
Cannot install Windows Server 2012 R2 on Dell Power Edge 2950.   I have Dell PE2950 with SAS drives and Perc 6/i controller.   Using the Dell live support DVD, I upgraded the Perc 6/i firmware to the latest version  (  Also, upgraded the Server Bios to the latest for my system to 2.3.1.   Prior to attempting to install the OS, I used the Dell Live support admin tools to create a RAID5 virtual drive and activated it.   The RAID built and activated successfully with no issues.

When installing Windows Server 2012 R2 from flash drive, the OS can see the virtual drive, however, when trying to install the OS,  the OS installer gives an error message:   "We couldn't create a new partition or locate an existing one.  For more information, see the Setup log files".

After doing some Google research, I tried using diskpart to format and activate the drive.   I was able to do this, however, when trying to install the OS again, I still get same error message.

According to Dell's website, the PE2950 and its firmware is supposed to be compatible with Server2012 R2.   Any help would be appreciated.
This is what we've done:
Used RDS Start Menu GPO redirection: User Configuration -> Policies -> Windows Settings -> Folder Redirection -> Start Menu.

Selected Basic setting, Target folder location box “Redirect to the following location” and pointed to our shared Start Menu folder. Used "Move the contents of Start Menu to the new location” in the redirection policy, created temp user, redirected it's Start Menu and went back and removed check from "Move the contents of Start Menu to the new location” finishing that process.

That was months ago. I now want to add a new program available in the RDS server desktop environment (not RemoteApps). My question is this:

- since then we've edited security settings for some users for applications on the RDS server desktop environment (again, not RemoteApps) so when they're on that RDS server they can't use prgms we don't have that many licenses for - If i do another temp user, install the new pgrm and redirect the Start Menu to our share again to include the new prgm - will that erase the previously-edited security settings we put in place on the limited-license prgms, wiping everything from the previous creation, or will that just add the new prgm to the redirected Start Menu?

thanks in advance!
I need to do test restores using our Commvault backup software. We backup several physical servers and since then are not VMs I need to to do file backups and restore the entire server to a large drive on a test server and i usually put then in a folder Servername-Restore. The restore process works fine but I eventually run out of space on the test server drive that I am putting these restores on. We are using a Windows 2012r2 Domain. When I got to delete the folder of the restore server I always get permissions issues and files and folder that will not delete. I am a domain admin and I take ownership of the folder and make sure inheritance is enabled but i still get permission problems and end up drilling down the C drive and D drive of the restored server and deleting one folder at a time. This is a lengthy process and last time I just reformatted the drive to make sure for other restores but it seems there should be a better way. I am missing something obvious? Is there a quick way for a domain admin to deleted a restored server all at once?

Keep receiving this error during my night duly so is there a way to check and troubleshoot without come again. Tks.

Add a new Windows server 2012 to a Windows server 2008r2 domain. This new server is a VM that will be running SQL. There is already a couple of server 2012 on this domain.
Our NTFS file permissions structure has become very polluted with duplicate security groups that have the same level of permissions in most cases for each duplicate. This is causing the users assigned to those security groups to be denied at the folders/files with the duplication. We have used icacls to try and remove the duplicate security groups, but it is only capable of removing all instances of the security group from the folder/file. Since we have a very large NTFS share it would take weeks to go through all of the folders/files to remove the duplicates. Is there a tool, script, or command that we can use to remediate this issue. Thank you in advance.
Hi Expert,

I have a SQL Server 2008 R2 on Windows Server 2008 R2 which is running on AWS. Team decided to upgrade this server into a separate RDS which will be SQL Server 2016 on Windows Server 2012 R2. My question is how to migrate database from one RDS to another RDS?
Hello Experts,

We've created remote desktop users in windows server 2012 R2 Standard & every user have an own folder in D: drive, how to restrict to folder access to user among themselves along with d: drive. Only one folder everyone can access e.g. D:\FTP.


Remote User            Folder in D:\            Allowed Access            Restrict Access

administrator      N/A                        Complete D:\            N/A

Our our ADFS 3.0 server our Global SSOLifetime is set to 480 Minutes and our test relaying party trust is set to 15, At the global level I do see that persistenct is enabled with  lifetime of 10,080 minutes. OUr test relaying party is not prompting users each time they access it. Is this because persistence is enabled or the fact our SSO Lifetime is set to 480 minutes?
We have Windows Server 2012 R2 and I just saw that drive C: is running out of space. I have noticed that the problem is in a folder called "C:\inetpub\logs\LogFiles\". For example, folder "C:\inetpub\logs\LogFiles\W3SVC3" occupies about 17GB and there are several like this, 6 in fact (W3SVC1, W3SVC2, W3SVC3, W3SVC4, W3SVC5, W3SVC6).

Can I just delete the folders and/or the content?
Maybe I also need to configure which events to log but I do not know how, I am not a Windows Server expert.

Best regards.

Trying to set up word press on Server 2012. Server is non domain joined, no GPO, no static IP, no AV or threat protection of any kind, No Windows firewall. Brand new VM, behind company firewall. I download windows web platform installer (both 4.6 and 5.0 and get the following:

Windows 7 pro workstations sometimes hang after login at welcome screen connecting to Windows 2012 standard server, hard booting and trying again will resolve mostly.
Found event 5719 "This computer was not able to set up a secure session with a domain controller in domain (Name) due to the following: There is currently no logon servers available to service the logon request.

We are using server 2012 . There already have one domain controller A in this child domain . After one more domain controller B added, we found this new domain controller does not have netlogon and sysvol in local share and GPO cannot be added. Then i noticed there have been replication problem with other child domains going and i resolved it . But the netlogon and sysvol still don't appear . I tried add one more new domain controller C and it is the same . I attached the screenshot of the event viewer after controller C prompted  . Please help me to resolve this thank you.
I have a domain controller where a GPO controls legacy audit settings.
For example, "Audit directory Service Access" is set to "Success, Failure".

However, when I run "auditpol /get /category:*", it says

 Directory Service Changes                    No Auditing
 Directory Service Replication                No Auditing
Detailed Directory Service Replication No Auditing
Directory Service Access                         No Auditing"

The GPO governing audit settings for this DC also has the following setting se to "Enabled"
"Audit: Force audit policy subcategory settings (Windows Vista or later) to override audit policy category settings".

So it means that Directory Service Access is not enabled, right ?

Good day

We have and SNMP Check error on one of our client servers

We have a Windows 2012 R2 RDS server.  For the last 5 days, that box goes through periods of serveral hours where connectivity is very spotty.  RDP sessions won't connect or disconnect after just a few minutes.  Sometimes it won't even ping at all, or pings with very slow response times.  When it's not pinging or pinging slowly, we can't RDP or VNC into the box at all.  We have replaced the NIC, patch cable, switch port, and rebooted the switch it's plugged into.  Nothing helps.  It just gets better on it's own and then breaks on it's own.  Rebooting the server or rebooting the switch will sometimes get it going again, but RDP sessions will continue to disconnect after a few minutes until it just decides to get better.  We even hooked up a second NIC with a seperate IP address, and we get the same results with that NIC.  It affects both our local and VPN clients PCs, which are a mixture of Windows 7 and Windows 8.  I'm lookiing for any ideas here - I'm pulling my hair out.
In our domain, the servers that previously were used for Public Key Services have all been decommissioned through failure.  I need to confirm if it is safe to remove the entries from AIA, CDP, Certification Authorities, Enrollment Services, and KRA or if there is a cleaner way to do this.
Hi guys.

I need to implement a security baseline for our Windows 2012 R2 Domain Controllers.
At the moment, the following two settings are configured as "Not Defined"

* Network Security: Allow Local System to use computer identity for NTLM --> to be set to Enabled
* Network Security: Allow Local System NULL session fallback --> to be set to Disabled

I have read some articles online but I still have some doubts about what they do exactly and what the impact of modifying per above would mean.
I would really appreciate if anyone can chime in and share their experience with these two settings.

Thanks so much.
Hi Experts,

I wrote a SharePoint(2013) web parts using visual studio(2017) and deployed in windows server 2012.
Only co-worker and I accessed it, but a few instances of iexplore.exe are spawning like every hour in task manager and it gets more than 60 over night and we had to perform clearconfig cache and iisreset /noforce on the servers in farm,
However, I found out that if I deploy this web parts app thru the visual studio and test, this is NOT happening.
I am not 100% sure but I don't think this is code issue, but server issue. I googled, but couldn't find any SharePoint web parts and IE spawning multiple processes issue.
Any comments or tip will be appreciated.

There is a problem with trust domain relationship issue that the domain admin can't remote login anymore.

I've checked the server hostname still join as a domain and can login local admin account.

Should I disjoin to workgroup and rejoin to the domain. Will this solve the issue. See attached error.

I am trying to install a new print driver on my print server which is also Domain Controller.
But it ends with error "Unable to install xxxx, type 3 - user Mode, x64 driver. The data is invalid.
OS is windows server 2012 R2.
The same driver can install on other server with same OS.
I tried some one more print model too and got same error. So i believe its something like restrictions.
Can anyone experience it before? any solution?
