Stuart's questions

We've got a service running using a Group Managed Service Account on a Windows Server 2016 host (HostA).

We're extending the functionality of this service so that it runs an R script which needs to access a file share \\HostB\Data on another Windows Server 2016 server. This is running third party R code - so it's not something we can easily change.

We've granted access to the gMSA using normal File and Storage Services - and restarted both servers just in case something was caching permissions.

However, the R call called by the gMSA to list.files on the HostB shared folder fails with a "file not found" error.

The same R code runs fine on my user account which has similarly configured share permissions.

Is there anything else I need to configure on the server which is sharing the folder? e.g. does the gMSA need login permission on that host? Or does that host need to be able to retrieve the password for the gMSA?

I'd like to run iis-express within a user session on a windows terminal services server.

However, I'd like only my current user to have access to the iis-express hosted site. Is there a way of achieving this, or does localhost have to be available to all users on that server?
