Hello List, I have another problem that I'm seeing more and more of. The symptom is my users lose their home page, it reverts back to MSN. I set the home page in a GPO. When I look at the eventvwr I get the Userenv 1104 event that basically says windows can not resolve the WMI filter. My filter is: root\CIMv2 Select * from WIN32_OperatingSystem where caption ="Microsoft Windows XP Professional" AND CSDversion= "Service Pack 2". This filter has been in place for over a year and now it is failing. It looks like WMI is not working but I have followed the procedure in KB 278316 to create a new sdb and I have stopped and restarted the WMI service. I have also found KB 814613 which states "Group Policy Processing Stops After you apply a WMI filter to a GPO"; which is not very comforting to say the least. Any ideas on how to fix this? Thanks in advance for your help. Mary Collingwood We Energies - IT Services Client Device Integration
