TPAHTS broken by Windows update

We do not yet know which Windows update (or updates) caused this problem, but it is one (or more) of the following updates.  These were applied by a US licensee this morning which caused the PAHT problem Ian notes; backing out these updates and rebooting the web server resolved the problem without needing to reinstall the PAHT service:

If we are able to determine the exact update or combination of updates that led to the PAHT problem we will pass on this information.

Subject: [Tessitura Technical Forum] TPAHTS broken by Windows update

Hi

When we upgraded to v11.0.3 on Tuesday, PAH stopped working. Took us a while to realise, but it was actually a Windows update that broke it, not the Tessitura upgrade. (thanks Caryl @ RAH!)

Error in the PAH log is System.Runtime.InteropServices.COMException (0xFFFFDF2B): Exception from
HRESULT: 0xFFFFDF2B

Does anyone know exactly which update it was? It takes ages uninstalling an update and we installed quite a lot of patches on Tuesday. Windows Server 2008.

Thanks!

Ian
