Vmware KB:

The PSOD is because of a race between reset and data path. There are two issues here:

Tx queue xmit and completion path ran into a race

The above race caused queue stuck and uplink reset, which ran into the PSOD.

Identified thanks to these legends in the vmware reddit:

https://www.reddit.com/r/vmware/comments/dan3k3/pf_exception_14_in_world_2481950vmnic00tx_ip/

 

Fixed in later driver release:

Bug Fixes:

———-

– Fixed intermittent TX hang due to race condition between start and stop of TX queue.

– Fixed duplicate nic reset due to race condition between uplink reset and watchdog threads.

Check the user is connecting to Exchange via MAPI , I had a few setups where users were set to Active Sync instead

In this case, the solution was to run both commands on the exchange server:

Set-AutodiscoverVirtualDirectory “SERVER\Autodiscover (Default Web Site)” -WSSecurityAuthentication $True

Set-WebServicesVirtualDirectory -identity “EWS (default web site)” -WSSecurityAuthentication $true

This two command solved my problem

Active Directory Domain Services could not transfer the remaining data in directory partition DC=DomainDnsZones,DC=[domain],DC=local to
Active Directory Domain Controller \\red.[domain].local.

“The directory service is missing mandatory configuration information, and is unable to determine the ownership of floating single-master operation roles.”

This is becuase a legacy server is still the “fSMORoleOwner” for DomainDnsZones and ForestDnsZones

Download fixfsmo.vbs from below

 

https://support.microsoft.com/en-au/help/949257/error-message-when-you-run-the-adprep-rodcprep-command-in-windows-serv

Run this script on the server which has all the FSMO roles

cscript fixfsmo.vbs DC=DomainDnsZones,DC=[domain],DC=local

cscript fixfsmo.vbs DC=ForestDnsZones,DC=[domain],DC=local

Recently a newly installed Vocus link was running 100mb Down but only 30mb up , multiple back an forths with support showed the link back to vocus was fine , however the speed was still bad.

Finally they told me the answer , the package ordered was not full 100mb up!

Best Effort Internet Access
VBU is delivered to site using Telstra Wholesale Ethernet Access (Fibre) Standard CoS (Class of Service) access tails. Note Standard CoS is 100% EIR (Excess Information Rate) which means, under congestion in the Telstra network, this traffic may be discarded. If the customer requires an Internet Service with continual sustained throughput or other medium to high performance requirements, please use Vocus IP Transit or Enterprise Internet rather than VBU.

 

Fix

Recommended VCT or VIE onnet service
or alternatively Telstra tail can be made premium.

Recently we changed the IP and Subnet of an exchange 2016 server. Trying to Open ECP Showed the Error :

Topology Provider coundn’t find the Microsoft Exchange Active Directory Topology service on end point

This is due to the Server Microsoft Exchange Active Directory Topology not starting

The service was not starting because of the new Subnet was not listed in Active Directory Sites and Services which meant Exchange was not site aware

Add the subnet and restart the server
