Remote Communication Service (Windows Slaves running as a service)

[Dunnigan, Terrence J]

Hi all,

 

I’m trying to configure some Windows 7 workstations to connect to our Jenkins server via a Window service. Currently they connect just fine over JNLP but we have traditionally experienced fewer issues when connecting via DCOM.

 

I’m stuck early in the process, when Jenkins uses Remote Communication Service to detect if Java is installed on the system. I’ve verified that Jenkins copies RemComSvc.exe from the server to the client’s C:\Windows directory but then nothing happens.

 

The console output is:

 

Connecting to mwdev05bltsgs

Checking if Java exists

ERROR: Failed to prepare Java

jcifs.smb.SmbException: 0xC0000205

     at jcifs.smb.SmbTransport.checkStatus(SmbTransport.java:563)

     at jcifs.smb.SmbTransport.send(SmbTransport.java:664)

 

System specs:

 

Server: Jenkins v1.544.3 running on Windows 2008 Server and Java JRE 7u72 server.

Client: Windows 7 running Java JRE 7u72 64 bit. JAVA_HOME is set to Java install path, and the System PATH contains %JAVA_HOME%\bin.

 

I have numerous other nodes connected successfully using this setup via DCOM but for some reason there’s a handful that refuse to advance past the “Checking if Java exists…” stage.

 

Does anyone have experience troubleshooting this particular issue? Is there a way that I can manually invoke RemComSvc.exe and see the results myself?

 

Thanks,

 

Terry
