Userenv Errors 1504 and 1509 in the Windows XP Application Event Log After You Apply a Redirector Hotfix (826379)

SYMPTOMS

Users have assigned roaming profiles on a network share hosted on a Network Appliance (NetApp) Filer. After you apply a recent Windows XP Post-SP1 redirector hotfix (for example Q811492 or Q816557) to a Windows XP-based client, sharing violations may occur while the profiles are written back from the Windows XP workstations to the NetApp filer. The files that are not written back successfully appear as *.tmp files after the user's next logon.
