I have just recently updated a lab to ZCM 10.1 from zen7. They are all XPSP2 boxes with 4.91SP2 client. On occasion I have some login issues where the DLU account is not created and I get a Windows login prompt. But more so when the machines are logging out, they tend to hang at the prompt "Windows is saving your settings". I am assuming that this is when the DLU account is being deleted and something is not breaking connection. Any help would be greatly appreciated.
