Adding additional SMTP servers in Windows 2003 Server
Posted on 2005-04-22
Very strange thing going on with Windows 2003 server and the SMTP service. Can't find any info on the web related to my problem.
I setup and installed a Win2003 server with IIS6 in Jan. 2004. When I set it up, I created 4 SMTP servers each having there own IP address. (So a CFMX app can distribute mail across them, seemed to have a performance boost v.s. sending all the mail to the 1 single default SMTP server that IIS gives you.)
I want to duplicate my setup on another server and have installed another brand new install of Win2003 server with IIS6 and for the life of me cannot setup multiple SMTP servers. The machine has multiple IP addresses bound to it, but when I try to add another SMTP server the second step of the wizard gives a drop down box that does not include any of the additonal IP addresses bound to the machine. So I can't setup additional unique SMTP servers with there own IP addresses. Crazy right! But it gets better.... When I look at the original server that has 4 SMTP servers and is working great, and try to add a 5th, (yes I have an IP available) it does the same thing! Second step of the wizard shows a drop down box with 1 IP address, none of the ones I want to use. When you setup a new IIS instance the wizard lets you type in the IP address, but the SMTP server does not let you.
I think maybe a MS update has screwed up IIS, becuase I swear when I first set this up, I typed in the IP's for the additional SMTP servers, this drop down box thing might be new......
Does anyone have an idea of what the problem is? Can anyone replicate my problem? Go ahead, try and setup your Win2003 server with multiple SMTP servers (not virtuals, but whatever) each with their own IP address.
