Hi List, I have a problem I'm hoping someone can shed light on. We have XP Pro w/sp2 on our workstations. Recently one of our Firewall exception GPOs became corrupted. That is, we could not edit it and received access errors. I restored from a backup and created an additional GPO. Does anyone know if there is a threshold for number of exceptions listed in this GPO? The reason I ask, I had a similar problem a year ago when trying to add an exception. At that time it was obvious that the GPO would no longer accept new entries. I created a second GPO and split the settings into the two GPOs at the time and everything was copasetic. I'm thinking that we may have reached the threshold again on the second GPO. Also, it seems that some of our workstations had group policy broken on them if the GPOs followed the corrupted one in ranking precedence. Is that probable? Would the CSC become unstable if one of the polices was corrupt? Thanks for any help you can provide. Mary Collingwood We Energies - IT Services Client Device Integration
