"Page cannot be displayed" WinMe/IE6sp1

[alabutler]

When I started working on this system, the modem would not connect, so I replaced the modem. That allowed me to connect. When I try to open a web page I get "This page cannot be displayed" and at the bottom of the page it reads "res://C:\WINDOWS\SYSTEM\SHDOCLC.DLL/dnserror.html"

I have followed all MS advisories; have run stinger to check for current viruses; downloaded and ran adaware 6, which cleaned up some references; ran lspfix and a couple other utilities that fix the winsock2; checked for newdotnet and webhancer; removed AOL and AIM; reinstalled ME; of course, started by deleting temporary internet files, cookies and history PLUS all *.tmp and ~*.* files in the temp folder.

Friends, this one has me stumped. I followed a thread posted by grandam and it sort of petered out before offering a resolution. Short of reformatting, anybody got an idea?
