HTTP 503 Error with Autodesk Vault Server

HTTP 503 Error with Autodesk Vault Server

Are you getting a HTTP 503 Error with Vault Server? Microsoft’s latest batch of Windows 10 updates have been linked to breaking Vault Servers.

It has been discovered that the latest Windows 10 updates are changing IIS user account permissions and so the application pool directories are no longer set appropriately. This results in the IIS Application Pools not starting and you get the HTTP 503 error.

How to fix it
To fix this fault please follow the below steps:

503 Error Fix
  1. Go to the drive your IIS is installed on, eg C:\inetpub\temp\appPools\
  2. Delete the directory (or visual directory) with the same name as your app pool
  3. Recycle/Start your app pool again
  4. **Check to make sure all Vault IIS modules are installed

If you are still having issues and the ADMS Console won’t start, please test IIS by making sure you can get the default IIS webpage:
http://localhost
Once this is confirmed working, test that you can get one of the Vault API pages to load:
http://localhost/AutodeskDM/Services/InformationService.svc

Conclusion
Microsoft are constantly updating and patching Windows and issues like this are common where an update changes a setting that other applications depend on. This is a minor setting change and is easily resolved with the above steps.
