Windows cannot process the object with the name because of the following error: there are no more endpoints available from the endpoint mapper

When trying to add a user to the local admins group on a Windows 2003 Enterprise edition server, I get the error.  Windows cannot process the object with the name because of the following error: there are no more endpoints available from the endpoint mapper.

I restarted the netlogon service, confirmed that time matched up to the DC, plenty of disk space, a gig of Ram free, and connectivity to DNS servers works.  

Any other ideas ?

There is a lengthy article here on trying to resolve it

As you can see there they are pointing you to first look for firewall/port issues.

Any events in your logs and does dcdiag look ok?

Thanks

I got for the solution & somewhere,i found the below solution.
1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
3. If the EnableRSS registry entry does not exist, create it.
To do this, follow these steps:
a. On the Edit menu, point to New, and then click DWORD Value.
b. In the New Value #1 box, type EnableRSS, and then press ENTER.

4. Right-click EnableRSS, and then click Modify.
5. In the Value data box, type 0 (zero), and then click OK.
6. Exit Registry Editor.
Try above solution & if it doesn't work try to reset the secure channel,by disjoining the machine & rejoingin it with different name.

Check there is no firewall blocking the client request on problem server & there is no dns issue on the DC.
