I wouldn't get this error if there were no servers available? I want to make sure that there is no chance that this is caused by code within the WConnect application.

I don't think so. When something goes wrong in WWWC you'd see a reference to wc.dll in the error message or something related to the COM system. This message is related to IIS generating messages on its own on error conditions or invalid URLs I think... anything where IIS is generating HTML on its own.
