Cause
The unlisted file extensions option in the applicationHost.config file was edited to not allow unlisted file extensions. For example:
<requestFiltering>
<fileExtensions allowUnlisted="false" applyToWebDAV="true">
Solution
1. Edit the applicationHost.config file under %windir%\system32\inetsrv\config\ to revert the unlisted file extensions option to its default value and save the file:
<requestFiltering>
<fileExtensions allowUnlisted="true" applyToWebDAV="true">
2. Restart the IIS Admin Service in the Services MMC.
3. Re-try the Surveillance login.
