Multicast "slow" on 2.5.69

Hi,

I have a multicast based application here that, essentially, consists of
a server and client. The client multicasts for the server which
responds with a direct tcp connection back to the client (the client
embeds it's IP address and port which the server should contact, in the
multicast request).

Under 2.4.20 the server and client can be co-located on the same machine
or run across the network successfully.

Under 2.5.69 a co-located client and server are slow to communicate - of
the order of several minutes and if the server runs under 2.5.69 with
the client on 2.4.20 on different machines, it doesn't seem to work at all.

So, I was wondering if anyone had any thoughts on what I should be
looking at/for in this case?

Thanks,

Dan.
