Author After getting latest code from TFS, I compiled and installed the latest build assemblies in GAC and from then my commerce server application stopped working. I was getting error “Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information”. The stack trace is shown below.

By seeing the stack trace, we can easily figured out that this error is commerce server (Microsoft.CommerceServer.Runtime) and it may not able to load the assemblies mentioned in the types section in web.config file but the assemblies (runtime and custom assemblies) are already exist in GAC. I binged, but not able to find concrete solution as this error is not specific to commerce server. I checked commerce server web services and found they are working fine and came to narrow conclusion that this error is due to some of the application code (not Commerce server assemblies).
Finally, I uninstall all application assemblies from GAC, does fresh compilation (rebuild) and put the new assemblies in GAC which has fixed this error (I have done machine restart due to some other issue). This looks strange but I felt that one of the assembly might of not compiled properly nor got register in GAC properly which has triggered this error. So, if you are getting same error in commerce then do the same way and hopes this will fix the issue.

After periodic password update to our application service account, the staging environment stopped working. When I right click and start the project, the process keeps on aborting and in the event log, I am getting “Remote authorization failed to server hl-stage-web. Ensure the service has access to this server.” error.
With the error description, I can easily understand that the account on the source machine could not log onto the target machine but the same account is running in all environments (WIP, pre production and production environment). To temporary fix this issue, I have right clicked on the project, select properties. Click on destination server and press edit button. In the dialog box, I have explicitly provided the user name and password (as shown below). Once done, the staging service start working properly.
Later I found the root cause: If the account user names are the same on both ends, then the passwords do not match or the account on the target does not have sufficient permissions. It may also be that the domain/server managing logons for that remote domain is not responding. The recommendation is to ensure that security is set up correctly between the two machines and that the domain on the target end can validate logons.
