PCO WDSL Link Not Generating

[benwildridge]

We seem to be having hit and miss results with getting our PCO installations connected to our MII server. We have a successfully connected a couple of Windows 10 machines using version 15.5.0.8 of PCo however some just fail to generate the WDSL link on the local machine.

Here is what we have checked;

• PCoMainServer is running
• Net.TCP Port Sharing Service is running
• PCo is being run as administrator
• Tried downgrading to 15.4

We can also see there are active connections to the PcoManagement address from the agent

Any suggestions of anything else to try are welcome.

We have found in the logs that we get this in the machines that are failing

You should add the SAP PCo tag as well.

Added it, thanks 🙂

For anyone that comes across this in the future this is the response we had from SAP

First of all, please, refer to SAP Note 3084957 and the part about port 808:

"

• Port 808 must either appear as unused or be occupied by the program SMSvcHost.exe. If another program appears here, the Net.Tcp port sharing service does not work properly. It has been observed repeatedly that an Intel screen driver also occupies this port. This is incorrect. In this case, update the relevant screen driver.

• The port that you have configured as a port for the management services must also not be occupied by another process.

"

This does seem to be the case for us confirmed by utilising the netstat cmd on the pc we can see the intel graphics PID against port 808, we are looking to update the driver to the latest version to see if it resolves the issue. Any further issues I will update.
