vCenter ADAM_VMwareVCMSDS event logging every 1 minute

First off, if you are using VMWare to virtualize a datacenter you need to vCheck if you’re not rolling your own solution.  If I had a ton of fingers, i’d be using them to count how many times it’s found issues that needed to be resolved within my vCenter; it’s a priceless tool.  That being said, vCheck found this little bugger for me in the event logs that I thought was resolved in vSphere 5.0, but as I converted to 5.1 it reared it’s head again, thankfully it’s a quick and easy fix.

Active Directory Web Services encountered an error while reading the settings for the specified Active Directory Lightweight Directory Services instance. Active Directory Web Services will retry this operation periodically. In the mean time, this instance will be ignored. Instance name: ADAM_VMwareVCMSDS

A few years ago I came across this article which outlined the fix which was simple.

Open the registry editor and browse to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ADAM_VMwareVCMSDS\Parameters

There is an existing string that is called “Port SSL” delete it.  Create a new DWORD named “Port SSL” and set it’s value to 636.

You then need to restart the services that reference these entries which are VMwareVCMSDS and the Active Directory Web Services.  Im a big fan of restarting the whole server for this change, but it’s not necessary.
