Group Policy, IE7 and Proxy Settings not applying

Windows server 2003 applying a group policy pushing proxy settings out to clients per username.  Stopped working and tried everything.  For us it was the entries in the exceptions list of  “Do not use proxy server for addresses beginning with”.  I cleared out all the entries and reran a gpupdate /force and now the proxy settings show up.  Going to have to add one at time and see what entry was causing it to fail.  The following is a link to what helped solve my issue -     http://forums.techarena.in/active-directory/1202115.htm
