McAfee preventing Windows 7 logons

We are experiencing what appears to be a growing problem with Windows 7 and McAfee 8.8 preventing logons via AD. There
isn't much information to provide since we have been unable to see any logged activity either in Windows or in the
McAfee logs to help diagnose the problem, yet when we disable the Access Protection feature the logons will proceed
normally. The other odd behavior we are seeing is that this seems to only affect new users/logons. For example,
existing users who had successfully logged on to the computer previously (either prior to installing or upgrading to
McAfee 8.8) do not have the problem. We believe that McAfee (or something else?) is preventing the creation of new
profiles in the c:\users directory.
Some of the workarounds being used are safe mode booting, let the user logon (basically creates the profile), and then
reboot in normal mode after the profile is created on the computer. We also tried putting in an exception for the
c:\users directory and the logons can proceed normally.
If someone has experienced this problem and has a viable solution we would like to hear from you.
