Can I reconfigure my Windows client to trust the bogus root to avoid error messages and enable logon to services like Passport?
Yes, although this is not a recommended configuration. You should never make this configuration change on a non-Test machine. • Visit a HTTPS site with Fiddler2 running, ensure that you see the Certificate Error warning page • START > RUN > CERTMGR.MSC • Drag the DO_NOT_TRUST_FiddlerRoot certificate to the Trusted Root Certification Authorities folder You can make a similar configuration change for Firefox and other clients that do not use the Windows Certificate store; use the appropriate Options dialog in the browser.
