Login Issues

[Chris_866]

I have been working with iLO's and RILOE's for quite some time now, but have just recently ran across a really strange problem. On a platform running XP, the user enters in login and password and when they hit enter or click login, nothing happens except the deletion of their login entries. It acts like nothing is trying to go further, or process anything, period. To verify this, the user can go to another workstation and log in just fine using the same login info., just not on their personal machine. I have set all security options to default, including all the advanced options as well. I am clueless, can any one please help me; considering there is a lot riding on this user and thier connectivity to this RILOE card. Thank you all very much.
