Re: Need help in DCOM

Hello,

I thoughed it was possible to configure your machine to use just one
port for dcom.
Could be wrong.
Anyway, it stays a bad thing to do.

Greetjes,

There is not 'a' DCOM port. It is in fact a range (from which a port is
chosen dynamically by the DCOM server), along with 139 (which
instantiates the DCOM server).

Michael Nelson (?) has good article on it in MSDN.

Hello,

It is not possible to use Dcom over a firewall, execpt if the
administrators open up the dcom port, which is a bad thing to do.... For
this you need to create a kind of webservice with or soap or .net...

Hi Manikandan,

First thing is that I do not get this:

i installed server in one machine which is in another
 machine and client in one machine which is in another machine

Do you mean different subnets or networks? If so you must set the
default gateway for client and server. And by the way did you set DCOM
setting on the client specially "Run component on this computer:
myServer"?

Second thing is that I believe you must have given server name (computer
name or NetBIOS name) when you used clireg32.exe, I am not sure if it
works with IP address. I think you had better try that as well.
