Question:
I’m getting an NSTATUS error 0x800706BA when testing my Windows credential. Could you tell me what this error is indicating?
Answer:
Error code 0x800706BA indicates that the remote procedure call (RPC) server is unavailable. This error can occur on ‘workgroup’ devices not joined to a Domain where the Windows inbound firewall rules are not permitting WMI queries. You can confirm this on workgroup Windows devices by verifying the following inbound rules are permitted on the Windows device:
Windows Management Instrumentation (ASync-In)
Windows Management Instrumentation (DCOM-In)
Windows Management Instrumentation (WMI- IN)
RPC failure for domain systems can indicate a permissions issue on the remote device. Please find the below link for resolving RPC failures:
