We have a two-server MBAM setup in our enterprise. It has been in use for eight months with good results. Lately I found some clients have never been able to contact the MBAM server. Neither compliance data or recovery keys are uploaded. When checking the client's event log - I find the following admin messages: Event ID 4 An error occurred while sending encryption status data. Error code: 0x803d0008 Details: A quota was exceeded. Event ID 2 An error occured while applying MBAM policies. Volume ID:\\?\Volume{7a6627e1-abf4-11e0-b703-5c260a5c8847}\ Error code: 0x803d0008 Details: A quota was exceeded. No Operational logs exist. I would be very thankful for some advice on how to resolve this issue. What I tried so far is: -Added NoStartupDelay=1 and reduced the check-in frequency for the MBAM client. -Added DisableMachineVerification=1 on the MBAM server -Reinstalled the MBAM agent -Restalled Visual C++ 2008 redist
