network application startup

[Droopy]

Hi,

It is more a design or architecture question but as I am using C#, I assume
it is the right news group to post.
I wrote a Tcp messages routing service that run on many PCs.
At startup, a service must connect to all running services.
Currently, I send an UDP multicast message when a service is started.
All running services answer to this message and a TCP connection is
created.
The problem is that with UDP messages, some services could not receive this
message so these services are not seen by the new service.

How could I solve this problem ?

Thanks in advance for your help,

Droopy.

May be my question was not clear enough ?
Should I develop a bit more or nobody can help ?
