AD RMS 2.1 - API Server is not Syncing templates from server

Question

Hello, I couldn't find any information on this before, apologies if this is a duplicate response.
We have a server running AD RMS 2.1, it's currently set up in production mode. We have an API that runs on IIS in that box which protects documents, among other things. IIS is running using the ADRMSSVC user, our AD RMS install is running with the ADRMSAdmin
user.
We have created 4 templates that we wish for the API to make use of when protecting documents, however those templates do not appear to be available to the application. In doing a SafeNativeMethods.IpcGetTemplateList call, we're only actually seeing one
of them. The ADRMSAdmin user, while running powershell Get-RMSTemplates only sees the same template.
I have turned off every caching option I can find, but it appears that neither of these users "knows" about the templates that we have created through the server. I have even renamed the template which is showing up, and that name change is not
being reflected through the API or powershell. If I displace the %allusersprofile%/Microsoft/MSIPC/Server/Templates directory,  I get an error through both those means that "The operation being requested was not performed because the user has not
been authenticated."
The machine is running in AWS - is it possible that resizing the machine has somehow voided the Machine Certificate, and therefore the machine cannot connect to ADRMS to get the new templates?
If it helps at all, I have exported the templates to a shared directory, and all 4 XML files that we have created show up there just fine.
Any help would be much appreciated.

i've been having this kind of problem as well. after so many troubleshooting, the problem is in the actual ADRMS webservices (/_wmcs/*). 
microsoft's ADRMS werbservices is maintaining an internal cache instead of querying for the list of templates from its SQL database. This cache doesn't get sync'd with its ADRMS database even when we change CacheMonitorTimeInterval and other cache related
policies in DRMS_ClusterPolicies!
I've also changed all the web.config of /_wmcs/ webservices so that cache is disabled but this doesn't work as well.
The only way to make the sync happen is to perform an IISRESET. Only then will the new and updated templates are returned by ADRMS webservices. now, that's just really retarded! Should I write a piece of functionality to recycle the app pool after every
request from client applications including Excel.exe? wow!
