Applies to

  • ONTAP 9

Issue

  • VSCAN server is still trying to access the ONTAP_ADMIN$ share by using its computer\machine account to authenticate (instead of the configured Scanner Pool Privileged user)

<node> ERROR Nblade.vscanBadUserPrivAccess: For Vserver "<vserver>", the attempt to connect to the privileged ONTAP_ADMIN$ share by the client "<ip-address>" is rejected because its logged-in user "<domain\computer-machine account$>" is not configured in any of the Vserver active scanner pools

after

  • Disable "Network security: Allow Local System to use computer identity for NTLM"

Error (vscanBadUserPrivAccess) frequently seen in the EMS log

  • Disable "Microsoft Windows Defender service"

  • This issue may be seen by the client machine/user as either Access Denied: File Infected (if mandatory Scan is on) or as Significant Latency for users as load increases (If mandatory scan is off)
