I am using Windchill PDMLink Release 11.1 and Datecode with CPS M020-CPS25 Our Windchill instance is 11.1 M020 and I have attempted to install the security patch CPS36. The install of the patch failed. Here are the errors that I faced DEBUG 2026-04-29 15:52:11 - Caused by: java.io.IOException: com.infoengine.exception.adapter.IEAdapterException; nested exception is: DEBUG 2026-04-29 15:52:11 - javax.naming.CommunicationException: redactedservername:389 [Root exception is java.net.ConnectException: Connection refused: connect] DEBUG 2026-04-29 15:52:11 - at com.infoengine.au.IEProperties.resetProperties(IEProperties.java:1217) DEBUG 2026-04-29 15:52:11 - at com.infoengine.au.IEProperties.resetProperties(IEProperties.java:1153) DEBUG 2026-04-29 15:52:11 - at com.infoengine.au.IEProperties.resetProperties(IEProperties.java:1099) DEBUG 2026-04-29 15:52:11 - at com.infoengine.au.IEProperties.resetProperties(IEProperties.java:1077) DEBUG 2026-04-29 15:52:11 - at com.infoengine.au.NamingService.setProperties(NamingService.java:1160) DEBUG 2026-04-29 15:52:11 - at com.infoengine.au.NamingService.newInstance(NamingService.java:265) DEBUG 2026-04-29 15:52:11 - at com.infoengine.au.NamingService.newInstance(NamingService.java:197) DEBUG 2026-04-29 15:52:11 - at com.ptc.jws.servlet.generation.ServletGenerator.(ServletGenerator.java:75) DEBUG 2026-04-29 15:52:11 - ... 120 more DEBUG 2026-04-29 15:52:11 - Total time: 10 seconds DEBUG 2026-04-29 15:52:11 - ************************************************************************ DEBUG 2026-04-29 15:52:11 - END: Failed to configure module rt.

For Windchill 11, typically this is a service called Windchill DS which is the LDAP that gets installed. Current versions no longer use this (free to chose any LDAP service you want). Basically, Windchill DS was OpenDJ repackaged for Windchill. If installed on your same host, there should be a separate service to start and stop it. It typically is installed parallel to your Windchill install.  If this is Windows, check services for this. If Linux, there should he a start/stop command or look in bin folder to commands.

Not Much info provided but I would start looking here 

CommunicationException: redactedservername:389 

Connection refused: connect

That level of failure needs help from PTC tech support not the community.

I have attempted a support case but was directed to post on the community.

Port 389 typically is your LDAP. Was that running when you attempted to install or were the stored credentials correct?

The redacted server name is the name of the Windchill server. It is a simple setup, just the one server. The Windchill and HTTP services were shut down at the time. Reviewing more of the log it does appear to be the connection to port 389 that is at the root of it. So, I assume it is some sort of LADP service on the Windchill server. How do I find that service?
