vCenter Event ID: 1209 / Source: ADWS

September 10, 2012


Following warning in the event viewer:

Log Name:      Active Directory Web Services
Source:        ADWS
Date:          03/09/2012 14:05:16
Event ID:      1209
Task Category: ADWS Instance Events
Level:         Warning
Keywords:      Classic
User:          N/A
Computer:      ***
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


Steps I’ve used to solve this problem (backup your registry!):

  • Open regedit and navigate to HKLM\System\CurrentControlSet\Services\ADAM_VMwareVCMSDS\Parameters
  • delete the Port SSL REG_SZ key (normally it has no value next to it)
  • create a reg_dword with the same name: Port SSL with the value 636

The warnings in the event log should disappear. Any comments or remarks? Don’t hesitate to give me some feedback
