Hi,

We have 6 sites, all Win2k SP4 DC's. Yesterday they all stopped replicating
data to their directories. When I ran dcdiag i got this error message;

EPT_S_NOT_REGISTERED

There are no more endpoints available from the endpoint mapper.

Error 1753


Does anybody know what this error means and why this has suddenly started
happening?

thanks

Jamie
 
Jamie,

This could be a networking error or a DNS error. Have you checked to make
sure that there is still connectivity between all Sites? Pinging might be a
start. Ping via IP Address and then via NetBIOS name ( so, if you have a DC
that has IP Address 172.16.32.30 and its computer name is DC05 then ping
172.16.32.30 and then ping DC05 ). Have you checked to make sure that the
networking hardware is live?

HTH,

Cary
