What that article is doing, is allowing you to pre-specify the ports that RPC will give back to the client. Normally, this is a process where the client attaches to the RPC negotiator and negotiates a port in the ephemeral range (above 1024). If you make those settings on your Exchange server(s) and GC(s), you're just telling the negotiator to hand out the same ports each time. You still need the negotiation which occurs on those potentially blocked ports. RPC/HTTP operates over TCP 443 but requires new OL2003 clients on XP+SP1+hotfix and Windows2003/Exchange 2003 infrastructure making it not as popular if you haven't upgraded so far. One of the more popular features as I understand it ;) Al -----Original Message----- From: Leonard [mailto:lmwangi@xxxxxxxxxxx] Sent: Thursday, June 10, 2004 1:51 PM To: [ExchangeList] Subject: [exchangelist] RE: Port 135 - 139 http://www.MSExchange.org/ Am looking at deploying RPC/HTTP but the article that Microsoft has specifies changing the Exchange SA TCP ports http://support.microsoft.com/default.aspx?kbid=270836 http://x220.minasi.com/forum/topic.asp?TOPIC_ID=9209 But in my exchange server registry i dont have TCP/IP key entries. Should I add this keys or does anyone has a suggestion on hoe to go around it?
