How do I solve a netlet proxy settings problem?

My user is getting the following message from the netlet:

"Netlet was unable to determine your browser proxy settings. If your browser preferences are set to use automatic proxy configurations, set the security proxy in your browser proxy configuration. Restart your browser, see your network administrator for proxy settings."

The user is using IE 5.5 on Windows 98.

The 3.0 admin guide (on page 207) talks about how to solve this for Netscape browsers but doesn't describe how to resolve it for IE browsers.

I believe this user is using a Verizon DSL connection, but I could be mistaken. I don't offhand know whether Verizon requires use of a proxy or not.
