When you create a new ZDD Server under the Serena network that has the correct or incorrect connection details when you enter an invalid userid and password whenever you reboot or logoff the machine when the machine starts up you always get the ZDD logon popup. This is not how it should be.
The attachment is a self-extracting ZIP file. Password is SERENA (all uppercase). Executing the zip file will generate a further file named V71102.CMAST.FIXES.D2012103.LOD that should be transferred to your mainframe in binary format to a dataset with LRECL=80 and RECFM=FB.
