Issue/Introduction

 The following error is observed when trying to update the Exchange server for an endpoint via Provisioning Manager.

:ETA_E_0007<MDI>, Active Directory Endpoint 'ADPROD' modification
failed: Connector Server Modify failed: code 51 (BUSY): failed to modify
entry:
eTADSDirectoryName=ADPROD.eTNamespceName=ActiveDirectory,
dc=prod,dc=etacom: [email protected]: JMDI: Failed to activate
connector on proxy connector server: localhost:20402; socket closed
(ldaps://myserver155.ca.com:20411)

CCS connector server crashes and restarts.

Environment

Release: 14.x
Component: IDMGR

Cause

A crash dump indicates that the problem is residing in the RPC layer. It seems something is wrong with network/DNS . Hence, unable to connect to the RPC server.

ERROR_CODE: (NTSTATUS) 0x6ba - The RPC server is unavailable.

EXCEPTION_CODE: (Win32) 0x6ba (1722) - The RPC server is unavailable.

STACK_TEXT:
02bdec58 7473fb4a 000006ba 00000001 00000000 KERNELBASE!RaiseException+0x48.....

This problem is happening while retrieving all domain controller server’s details from primary DC (DNS) by using RPC calls. This is used for failover purposes.

Resolution

We can bypass this failure by using a configuration file which is located in
<PS_HOME>\data\ads\<directory-name>.DNS (NOTE: directory-name is same as endpoint name).

<directory-name>.DNS need to be configured with all available DC server details - the order of the servers in the list is important therefore the DCs which are likely to be used (DC as well as Exchange servers) should be listed first.
