>I have been pouring over the MSDN on this problem and am comming up without any answers. I have a COM object on a NT4.0 Workstation in Domain X. I can call oMyObj=CreateObjectx(lcComID,lcIP_Address) from my workstation. Then I can call a Function in that remote object. and it works. I have another programmer on ISDN that is an Admin on that COM NT4.0 Workstation. He gets "RPC server unavailable" He can Ping the Machine with the COM object by name. I have had this same problem when I am logged in at home on a 56K line. We have never had a problem going across Domains to access COM before. Is there something about a slower connection that causes problems and if so does anybody know how to fix it? Thanks in advance.


We've had some problems in the past where we had to configure DCOM on the client to use the IP address of the server rather than the server name. We also had problems when the clients and server weren't on the same subnet.
