Windows Server 2012 member server reports - there is a time or date difference between your computer and the remote computer

  • 772

PROBLEM

Domain member service reports the following when attempting to RDP from any Windows 10 workstation on the same domain or any Windows client from an external source:

  • Remote Desktop cannot verify the identity of the remote computer because there is a time or date difference between your computer and the remote computer. Make sure your computer’s clock is set to the correct time, and then try connecting again. If the problem occurs again, contact your network administrator or the owner of the remote computer.

Member Server Event Log contains:

  • EVENTID 5719. This computer was not able to set up a secure session with a domain controller in domain due to the following: The RPC server is unavailable.

  • EVENTID 1054. The processing of Group Policy failed. Windows could not obtain the name of a domain controller. This could be caused by a name resolution failure. Verify your Domain Name System (DNS) is configured and working correctly.

ENVIRONMENT

MEMBER SERVER

  • This is the only server exhibiting the issue.
  • Windows Server 2012 Standard R2.
  • File server.
  • SQL server.
  • Event log reports errors above.
  • Cannot RDP to server when issue occurs.
  • DNS address set as PDC and SDC IP addresses.

PDC

  • Windows Server 2012.
  • Holds all FSMO roles.
  • GC.
  • Windows Firewall disabled for testing.
  • No ERRORS reported, operating normally.
  • AD services.
  • DNS service.
  • WINS service.
  • Can RDP to all nodes and autheticate with domain user credentials.

SDC

  • Windows Server 2016.
  • GC.
  • Windows Firewall disabled for testing.
  • No ERRORS reported, operating normally.
  • AD services.
  • DNS service.
  • WINS service.
  • Can RDP to all nodes and autheticate with domain user credentials.

EXCHANGE SERVER

  • Windows Server 2008.
  • Exchange Server 2007
  • Also added as a member server.
  • No ERRORS reported, operating normally.
  • Can RDP to all nodes and autheticate with domain user credentials.

WINDOWS 10 CLIENTS

  • All Windows 10 clients operating normally.
  • Can RDP to all nodes and autheticate with domain user credentials.

Some further information that maybe important:

  • I had another domain controller that died (vserver). It was manually removed from the domain using the correct procedure (meta data remove, transfer roles, delete from DNS etc). Satifited this is no longer and issue. Server name has not appeared in any error logs. DCDIAG on existing domain controller (PDC, SDC) reports no errors. This was many months ago.

  • When the domain controller (vserver) died workstations reported time sync issues. This was resolved on all client work stations using the W32TM commands detailed below many months ago. This W32TM has not resolved has not resolve the issue with the problematic member server issues documented here.

DEBUGGING

MEMBER SERVER

  • I can RDP and authenticate as a local user on the server when the issue occurs.
  • I cannot RDP and authenticate as a domain user on the server when the issue occurs.
  • If I reboot the server the issue is resolved for 24 hours approx.
  • Ensuring network firewall allows time queries to external sources.
  • W32tm /resync /rediscover (all executed elevated).
  • W32tm /query /configuration.
  • W32tm /config /manualpeerlist:time.windows.com /syncfromflags:manual /reliable:yes /update.
  • w32tm /config /syncfromflags:domhier.
  • net stop w32time && net start w32time.
  • GPUPDATE does not resolve the problem.
  • NIC settings have the DNS and WINS address set as PDC and SDC server IP addresses.
  • Removed from the domain , domain join again using wizard tools.
  • When the issues occurs NSLOOKUP will resolve internal sever.internal.com domain addresses.
  • When the issues occurs NSLOOKUP will resolve internal extenal domain addresses.
  • When the issues occurs google Chrome deployed on the server will not display a web page. DNS confirmed operatinal via NSLOOKUP. I have seen this behaviour from workstation that deployed the application FIDDLER as the IE PROXY address is set to the machine loopback IP. Confirmed FIDDLER not installed on this member server.
  • See REF1. Tested MMC, connect to computer , load SECURITY LOG.
  • Set GROUP POLICY to allow Allow Remote Administration Exception and Allow File and Printer Sharing Exception.
  • Confirm Windows Management Instrumentation service running domain controllers and member server.
  • Confirm TCP/IP NetBIOS Helper service is running on domain controllers and member server.
  • Confirm Remote Procedure Call service is running on domain controllers and member server.
  • See REF2. Enabled `FAST LINK' on servers managed switch port.

Granted these tests above were performed several hours post reboot when the issue has not reoccurred yet. I can repeat the test and post the results upon reoccurrence.

PDC

  • DCDIAG reports no issues.
  • NSLOOKUP resolves internal and external addresses.

SUMMARY

Seems clear its a time sync issue. I believe that is everything I have tried to date to debug and resolve this issue, will EDIT if I can remember anything else. Thank you for any help (desk / head / bang ). Keen to understand the root cause.

UPDATE-1

Edited following the comment from Joeqwerty (thank you Joe).

Current State

  • No reocurence of this issue to date , approx 24 hours since this article was posted.
  • No reboots.

Amendment

However the following change has been applied now (see REF3) on the problematic MEMBER SERVER:

  • Reg Key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type=NTP amended from NTP to NT5DS

  • Windows Time service restarted..

  • Output of w32tm /query /configuration now shows:

  • GPUPDATE applied

  • Type: NT5DS (Local) still displayed when checking w32tm /query /configuration.

I need to leave this for a few days and try a reboot before I can confirm the issue has been resolved.

UPDATE-2

  • Issue just reoccurred. An admin rebooted it before I could run any tests.
  • On reboot w32tm /query /configuration still shows Type: NT5DS (Local)
  • Will report back Monday.

  • FYI w32tm /query /status

Sorry for all the text.

UPDATE-3

No reoccurence of the RDP error document above yet but posted an update to highlight that at 0200 UTC the Member Server event log again started to report the EVENTID errors documented at the start of this thread chiefly:

    1. SOURCE NETLOGON. This computer was not able to set up a secure session with a domain controller in domain due to the following: The RPC server is unavailable.
    1. SOURCE GROUP POLICY. The processing of Group Policy failed. Windows could not obtain the name of a domain controller. This could be caused by a name resolution failure. Verify your Domain Name System (DNS) is configured and working correctly.

In the past I found this was a precursor to the RDP connection / time sync problem given enough time.

In response I execute the following all from the MEMBER SERVER experiencing the issue:

Warning:
Reverse name resolution is best effort. It may not be
correct since RefID field in time packets differs across
NTP implementations and may not be using IP addresses.

The amended NT5DS settings are still in place. Give it a few hours and the RDP issues will reoccur. Not sure where to go from here sorry.

UPDATE-5 10/07/17

72 hours since the last update the issue has recurred. RDP and attempt to authenticate with the domain administrator user results in:

Remote Desktop cannot verify the identity of the remote computer because there is a time or date difference between your computer and the remote computer. Make sure your computer’s clock is set to the correct time, and then try connecting again. If the problem occurs again, contact your network administrator or the owner of the remote computer.

    The member server is showing that it's using type AllSync and syncing with an external time source (time.windows.com). It should be using type NT5DS and syncing with one of the DC's. You should reconfigure w32time on the member server to fix that.
