Symptoms
The Avamar Downloader Service (ADS) is installed and configured to use a proxy server to access the Internet.
The personal computer's 'Internet Options' screen is also configured to use the proxy. It allows web browsers to access the Internet through standard port 8080.
If ADS checks for file updates, a manifest.xml file is written to the local ADS repository. No errors are reported in the ADS log and ADS believes it has successfully downloaded the manifest.xml file.
However, the file contents are invalid as they have been replaced with the following text:
Regular web browsers can correctly download the Avamar manifest.xml.
The proxy server requires clients to authenticate to it using a valid domain user's credentials.

However, the file contents are invalid as they have been replaced with the following text:
<HEAD><TITLE>Proxy Authorization Required</TITLE></HEAD> <BODY BGCOLOR="white" FGCOLOR="black"><H1>Proxy Authorization Required</H1><HR> <FONT FACE="Helvetica,Arial"><B> Description: Authorization is required for access to this proxy</B></FONT> <HR> <!-- default "Proxy Authorization Required" response (407) --> </BODY>
There appears to be a problem with the Avamar Downloader Server authenticating to the proxy.
Regular web browsers can correctly download the Avamar manifest.xml.
The proxy server requires clients to authenticate to it using a valid domain user's credentials.
Cause
The Avamar Downloader Service does not support proxy authentication.
Resolution
Avamar Downloader Service is incompatible with proxies which require authentication.
A workaround may be possible if the proxy server can exclude clients from the authentication mechanism based on MAC or IP address. Work with the proxy administrators to determine if this feature is available.
