I have a Windows 2000 Server, SP4, which is hosting a CISCO ACS Wireless Authentication application, ver 3.0. We have had 2 crashes of the ACS in the past week, where users can't authenticate to the network via wireless (Active Directory integrated). A reboot restores access.The above error has been evident in the event log, but I can't find anything about it in searching Microsoft's Knowledge base. I know the system needs a memory upgrade, as monitoring software points this out. Does anyone know what this error means, and what wil fix it?
