Fixed Port callback for messenger(?) server side?

#121612

Hi Guys,

I’m currently locking down our infrastructure over here, starting with enabling windows firewall (xp pro clients)

With the firewall enabled on my test ‘vm’ i can receive messages, but cannot reply.

I currently have fixed ports setup on the client to reflect ports 2030-2040

(on a side note, when i configure port exceptions for windows firewall, may i enter a range as such ‘ 2030-2040:TCP:localsubnet:enabled:Fixed msmsgs int)

I’ve read the article on ‘Polling and Fixed port callbacks’

Where on my exchange 2000 server do i enter the ports to be used for fixed port callback? Do i need a range of ports open, or would 1 port for everyone suffice?

I looked in the exchange servers registry, but was unable to locate the;

\HKEY_Local_MachineSoftwareMicrosoftExchangeInstantMessaging

entry, will i have to create these keys manually?

Also, in the part where it indicates what setting to modify, the only setting / keys i see are all related to port polling, no where can i enter the ports i specify on my client.

Do i basically need to enable polling for fixed port callback to work, and forget about setting the port value on the server?

Working on a production server is a pissoff when your window of opportunity is from 10 – 11 pm

thanks for all your help guys, much appreciated.
