On-prem data GW keeps creating junk files on C-drive

After installing a new PBI On-prem data GW 14.16.6549.2 junk files and folder a created on the C-drive

Example 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.

Re: On-prem data GW keeps creating junk files on C-drive

I'm experiencing the exact same problem, this started 20/12 for me. I'm running Windows Server 2012 R2 and Gateway version 14.16.6524.1

Re: On-prem data GW keeps creating junk files on C-drive

@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. 

 

Best Regards,

@v-qiuyu-msft The folders are located at the root of C:-drive. Here's a pitcure from the server.Power BI folders.png

Re: On-prem data GW keeps creating junk files on C-drive

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... Smiley Sad

I think that maybe post should be in "Service" part of forum not here...

Re: On-prem data GW keeps creating junk files on C-drive

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?

Re: On-prem data GW keeps creating junk files on C-drive

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.

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."Schannel.png

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:
Integrations with Files and Services
