Direct Access OTP ISAPI Extension Issue - DAOTPAuth.dll RRS feed

  • Question

  • Hello,

    We've recently deployed two DirectAccess setups (Individual setup contains two nodes with ELB) with OTP running on 2012 R2. Everything is working fine, expect that we have started errors from DA OTP Monitor on one of the DA node on each setups. 

    Despite this OTP Monitor error, OTP is working fine. We see successful events on DA Server (Event 10041 - DirectAccess OTP Authentication)  and DA Client (Event - OTPCredentialProvider).
    DAOTPAuth.dll is accessible from DA Server and DA Client (after OTP validation). 

    Time is Sync'd.

    DA Servers are patched and up to date.

    RAMgmtSvc.exe - 6.3.9600.17725

    RAMgmtSvc.dll - 6.3.9600.16523

    RAmgmtapi.dll - 6.3.9600.16384

    I've also tried BMR Restore after formatting disks but still, OTP monitor issue persists.

    Is this a known Issue? Any suggestions how to fix this?
