Recently, we noticed the downloading issue on the client machines. The applications and updates were stuck with Downloading 0% and received the below error in the DataTransferService.log.
Error : Error sending DAV request. HTTP code 500 status ‘Internal server error’ 0x800705b4
Initially, i thought the issue could be with 443 port connectivity failure to DP server so i run the below two URLs to test the connectivity.
https://<DP server Name>:443
https://<DP server Name>:443/SMS_DP_SMSPKG$
I run the 1st URL on the client machine and it displayed the IIS web page so there is no issue with 443 port from network side. But when i run the 2nd URL and received the below message so I decided that there is something went wrong in IIS on the DP server.
1. Logged into DP server and verified IIS service under services.msc & IIS manager, it was running fine.
2. Opened IIS Manager and verified certificate binding for 443 port & certificate expire date in certificate console and no issues with that.
3. Expanded Default Web site and Clicked on SMS_DP_SMSPKG$ -> IIS Authentication, noticed that all authentication were enabled state so disabled ASP.Net Impersonation & Forms Authentication and restarted IIS service. After that, the client machines are started downloading contents from DP server.
I hope this helps you. Thanks 🙂
