Compliance Reports Stuck in Processing

Symptom​

A compliance report in Netwrix Change Tracker never finishes running. The report's Status value shows Processing with a percentage that never reaches 100%.

Cause​

An IIS request-filtering tool on the Hub server is blocking the report data collection. The most common cause is UrlScan, which screens incoming IIS requests against administrator-defined rules and can be configured to block the Transfer-Encoding header. Netwrix Change Tracker uses Transfer-Encoding to gather report data from a remote system, so a filtering rule that blocks it prevents the report from completing.

Resolution​

If UrlScan is installed on the Hub server, stop it from blocking Transfer-Encoding:

  1. Go to the UrlScan install location, C:\Windows\System32\inetsrv\urlscan.
  2. Open the .ini file that controls the filtering rules in a text editor.
  3. Search the file for the Transfer-Encoding entry.
  4. Comment out the entry by adding a ; at the start of the line, so the line reads ;Transfer-Encoding:.
  5. Save and close the .ini file.
  6. Restart IIS.
  7. Run the report again. It should now reach 100% instead of remaining in Processing.

NOTE: If UrlScan is not installed, check for another IIS request-filtering or security module on the Hub server that may be blocking the Transfer-Encoding header, and apply the equivalent exclusion for it.
