go to c:\windows\system32\drivers\etc

open the "services" file with Edit or notepad. go down the list and search for the port for this, and change it to what you want it to be...

just ensure that all clients use the same port in the services file, else it wont be able to communicate.

Does not make sense, can you clarify ?

I understand the services file... how is this relevant to a depreciated SSL protocol ?

I think your previous expert saw "protocol" and interpreted it as "port".  SSL is a port-independent conversation that can happen on any port for any service.

David Wagner of UC Berkeley and Bruce Schneier have put out an excellent papaer on SSL version 3 and why the deprecation of 2.0.  http://www.schneier.com/paper-ssl.pdf

Now to disable SSL 2.0 and others, read and follow http://support.microsoft.com/kb/187498 and take SPECIAL note of the opening paragraph as to upgrading to 2008 IIS 7.0 or newer.

You'll also need to disable older ciphers, http://support.microsoft.com/kb/245030
