# Troubleshoot WDC Problems

Web Data Connectors (WDCs) are web pages that provide a data connection accessible over HTTP, for data sources that don't already have a connector in Tableau. This topic covers potential issues that you might run into with WDCs.

## WDC Extract refresh failed with error 'Render process terminated - render process crashed (exit code=-2147483645)'

We recommend that you use a Run As service account that is not in any administrator group for the computer Tableau Server is running on. This is a best practice for security reasons, but it can also impact connection issues with data sources and WDCs. The particular issue with WDC extract refresh failures is one type of connection problem that can occur if your Run As service account is a member of an Administrators group on the Tableau Server computer. To resolve this issue, update the Run As service account so it does not have any administrator privileges on the computer.

For details about this issue, see the [Tableau Knowledge Base](https://kb.tableau.com/articles/Issue/wdc-extract-refresh-failed-with-error-render-process-terminated-render-process-crashed-exit-code-2147483645?lang=en-gb).

For information about best practices when creating or updating the Run As service account, see [Creating the Run As service account](https://help.tableau.com/v0.0/server/en-gb/runas_acct.htm#best).
