I had our exchange server on an Pentium Pro 100 HP net sever with 196 MB of ram for about the first year we used exchange. It was the PDC, DHCP Server, Primary WINS, Ras server with 8 VPN ports and the exchange server with 180 boxes on it. Processor utilization rarely got above 50 percent. Lack of Hard Drive space, and memory, 196 MB was max for that box, were the reasons I took exchange off of it.
Microsoft says you should have one domain controller for each 10000 accounts if I remember correctly, and this was written in the days of Pentium Pro 100s being a kick butt machine. Unless you have thousands of users I really don't see the domain controller resource drain a bar to putting an exchange box on a PDC. However I would not recommend putting it on a box with anything else. It was a real bitch having to take down the DHCP for a day when I had to clean out the I Love you virus.

Wow, I thought my PDC (P133 with 128MB of RAM) was bad... -----Original Message----- From: William Lefkovics [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 21, 2002 6:07 PM To: MS-Exchange Admin Issues Subject: RE: Why would anyone install Exchange on a PDC? Dude... I upgraded our PDC from a P75 to a P133 32MB RAM that's still in production. IF you can afford Exchange, you can afford a cheap BDC. I applaud your dedication to those companies. -----Original Message----- From: Clark, Steve [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 21, 2002 1:25 PM To: MS-Exchange Admin Issues Subject: RE: Why would anyone install Exchange on a PDC? In the majority of shops I manage - there is no choice. Single server shops where the cost to have a BDC or even MS is over the budget. Keep in mind - the hardware is only a SMALL part of the cost. Most of the shops don't do Exchange - they go for POP mail. However, when the problem of shared contacts and calendars rears it's ugly head - Exchange is the solution.

I will always advise not to, but it works fine. The reasons not to: performance - not as big an issue today due to beefier machines recoverability - you better have a good BDC somewhere or tears are gonna fall.
