After installing a new PBI On-prem data GW 14.16.6549.2 junk files and folder a created on the C-driveExample of folders names:+360YjLX+XPUzmDSeJ+tr8t3XOXDiJvuh0OYpY69Bw=+LdWMP+iqbr+5doyd1DZiiFYd1OknhyH6F1m4YyHoo=+LtLM+aswqVWoa85K8onvUPgm78aexj4gx9VzlwGCM=and so on.About 10-20 new folders are created every day, and I really have to concentrate when cleaning them out so that the windows folder among others do not get removed! Within the folders, I find the exact same structure: Index - empty folder Temp - empty folder Cache.Key - file I have two other gateway installations NOT doing this, and I cant find anything in the logs explaining why those folders are created. I know it is the GW creating them because file owner is local account "PBIEgwService". Fist step would of course be to reinstall the gw but it runs a bounch data sources in a global company with a number of credentials, so the task of re-installing is quite excensive. And so I dont really like to do it if unnessesary.

I have also installed version 14.16.6614.5 and junk folders are no longer being created. The issue has been fixed in this version.

Just wondering if there's been an update on this. I am also experiencing the same problem, Windows 2012 server, gateway installed last Dec.

Also, can these files and folders be deleted without any problems?

Thanks.

henrik_nordling karlstrom Would you please share the path of these "junk" folders? I didn't find them in this path C:\Program Files\On-premises data gateway. Thanks.

I have faced the same problem.

On both servers where I have Gateways installed.
The same version as Yours (last one I thing).

Creating the gateway from scratch does not helped.
Changing service account to AD account either.

It looks very bad, IT departmet was warried that we have ransomware... :(
I think that maybe post should be in "Service" part of forum not here...

I have found in Windows log Error Events appeared at the same time that the folders ware created:
A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 48. The Windows SChannel error state is 552.

Next after this:
The certificate received from the remote server was issued by an untrusted certificate authority. Because of this, none of the data contained in the certificate can be validated. The SSL connection request has failed. The attached data contains the server certificate.

There is a lot of errors like that in System Log and not all of them correspond to created folders but MAYBE it is connected with SSL/TLS topic?

  My event log looks the same. A bunch of Event ID
  36888: "A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 48. The Windows SChannel error state is 552."
  36882: "The certificate received from the remote server was issued by an untrusted certificate authority. Because of this, none of the data contained in the certificate can be validated. The SSL connection request has failed. The attached data contains the server certificate."

  MarcinBajda, I have a lot of Schannel, event id 36882 messages on the server too.
  I totally agree, it could be related to the problem... not really sure how to fix that though. I have sent the info to a collegue that has more knowledget about the certs.

    Thanks for confirmation ;-)
    
    I hope someone from Microsoft (especially "Gateway Team") would get intrested in the topic...
    
    I think that better place for the topic is:

I am experiencing the same issue.

I checked and PBIEgwSerice has permissions to create but not to delete in the root of the C drive. I think that is why folders are being created and not cleaned up. But should it be using the root of C to store refresh cache data? Does anyone know where the path for storing refresh cache data is at? Registry entry? Config file? Wondering if that was corrupted during the install maybe.

Are others with this issue running the service under PBIEgwService or a different user? And does that user have permission to delete in the root of the C drive?

  That sounds like a good insight because this started for me some days after I upgraded the gateway on the server and changed from a AD-user to PBIEgwService on the service.
  
  I'm going to move the gateway to a new server, not sure whether I'm going to run it as the PBIEgwService or an AD-user. I'll let you know the result anyway.

    When I first saw that happened I reset the password for PBIEgwService and next decided to change default account.
    I have created new AD account and setup the service to use it.
    It changed anything :(
    Folders are still created on C drive.
