In this guide, we will reveal some of the possible causes that might cause Windows Error 1753 and then I will share some of the possible solutions that you can try to get rid of this problem.

This article describes the symptoms, causes, and troubleshooting steps for Active Directory operations to fail due to Win32 error 1753: “There are no more endpoints available from some adapter endpoints”.
DCDIAG reports connection test, Active Directory KnowsOfRoleHolder replication test, and test failed with error 1753: “No more endpoints to sell from Endpoint Mapper”.

REPADMIN.EXE reports that a replication attempt is returning withabout error status 1753.REPADMIN commands usually refer to the 1753 elevation, but are not limited to:
REPADMIN /REPLSUM
REPAMIN /SHOWREPL
REPADMIN /SHOWREPS
REPADMIN /SYNCALL
Sample output including “REPADMIN /SHOWREPS” showing how inbound replication from CONTOSO-DC2 to CONTOSO-DC1 fails, usually with a “Replication Access Denied” error:

The “Check Replication Order” topology in Active Directory Sites and Services returns “Typically, endpoints are no longer accessible from the Endpoint Mapper.”
Right-click on the source domain controller connector and you will see a message”Replication topology check failed” and “No more endpoints available from point resolver termination point”. The error probability on the screen is shown below:

The “Replicate Now” command in all Active Directory and Site Services says “No more endpoints from the Endpoint Mapper. A”Right clicking on any connection object from the source domain controller and selecting “Replicate now” fails with the message “No more endpoints to buy from the endpoint mapper”.The error information on the screen is shown below:

Try NTDS kcc
You can establish a replication connection for your current failed next writable directory partition.

The Consistency Checker (KCC) attempted to add a replication draft for the following directory partition as well as the source domain controller.
Reason
This article shows the RPC workflow, starting with registering an implementation withserver using the RPC Endpoint Mapper (epm) in step 1, and ending with the prepropagation of potential RPC client data to the client application in procedure 7.
ADD RPC Workflow
Server application registers element endpoints with RPC Endpoint Mapper (EPM)
The client negotiates to receive an RPC (on behalf of the user, the operating system, possibly an application-initiated operation)
Client-side RPC Internet connections to the target computer’s EPM and need to know that the endpoint is making a new client call.
EPM responses from a server that has an endpoint
Client RPC communicates with each server application
The server application launches the mobile phone and returns the customer’s RPC result.
Client RPC returns a by-product to the client application.
Error 1753 is due to an error associated with steps 3 and 4. Error 1753 specifically means that the RPC client (destination domain controller) can simply call the RPC server (source domain controller) on port 135, but “EPM through the server RPC (originalth DC) appears to be unable to complete the RPC interest loan request and returned Server Component Error 1753. The presence of all 1753 errors indicates that the RPC client (target DC) received a forum-side error response from the RPC server ( replication source AD DC) near the network.
