Your TN3270 server -- or AT-TLS as its proxy -- is using a server certificate. That certificate is signed by some CA. You will need that CA's root certificate installed in Windows. That CA might be
- The PKI group at your site - Some well-known CA such as DigiCert or GoDaddy - The server certificate itself if "self-signed." The first question you need answered is "who signed the server certificate?" Your PKI group should be able to tell you that. If you get the certificate in the right format -- such as .crt -- you can just double-click on it to install it in Windows.

I would like to enable PCOMM (14.0) to use a secure connection. It appears that I need to provide a certificate. IBM support told me to use RACDCERT to export the certificate and import it into PCOMM - that didn't work as there is no place that I can see to do such an import after I did a binary download of the cert file from z/OS to Windows. Can someone/anyone provide some guidance on setting up PCOMM to connect securely to z/OS (AT-TLS enabled)? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
