Wayne,
Here is the problem
"wt.wrmf.transport.WTTransportException: Authentication to"
This is the url that windchll uses to authenticate to your replica server, in the log, authentication is failing as authentication is being enforced on this URL. The issue might be in the changes you made to the app-windchill-auth.conf is causing this authentication issue. Also are you using siteminder? Siteminder has also being known to cause this sort of issue, there is a siteminder file called localconfig.config that a lines in it for ignoreUrl, any url on these lines would not have authentication enforced.
Hope this helps,
Thanks
