Recently, I installed smtp on my server. It ran fine for a<BR>while but then stopped working. The service did not stop but<BR>smtp will no longer deliver mail for the domain I have it on.<BR>When I go in to the MMS console and I select the "current<BR>sessions" dialog I am told that "The RPC server is unavailable".<BR>I have tried a reboot but nothing. Perhaps I need to rerun SP?<BR><BR>I am using NT 4.0 with IIS 4.0<BR><BR>Any help much appreciated,<BR><BR>Rob<BR><BR><BR><BR><BR>
