Creo Windchill registered Server not using .srv_mgr_db3.fldx

While using Creo with Windchill I am trying to run a trail file automatically (just to open the active workspace) after starting up Creo using the following syntax (not both lines work separately):

1. start "" "c:\my location1\parametric.exe" "c:\my location2\trail.txt"
2. start "" "c:\my location1\parametric.exe" -i:rpc_input "c:\my location2\trail.txt"

Even though both work, both have a strange side effect where I lose my registered servers and I have to re-register them.  What is even more strange is that it not only doesn't modify the .srv_mgr_db3.fldx file, I cannot find a file on my computer (or the network location where my batch file and other config files are stored) that stores the new server info.  When I restart Creo my trail file runs, and my workspace refreshes correctly, but it uses my new server registrations and not my old.  If I go back to using:

• start "" "c:\my location1\parametric.exe"

It starts using my original server registrations.  When I use a trail file, where is it storing my registered servers since it is evidently not in the following normal location:

• C:\...workspace\PTC\.ssappd\ServerMgr\.srv_mgr_db3.fld

Questions:

• In what file are these new registered servers being stored since it is not the .fdlx (in any location even in the userprofile, etc)?
• Why is it doing this when I add the trail file?
• How do I control the behavior and make sure it continues to use the .srv_mgr_db3.fldx file in my PTC directory?

Environment:

• Creo 7.0.11
• Windchill 12.0.2.16

Thanks! Lawrence
