First you would have to know the IP to find the MAC, the name will not help much with your MAC until to know the IP. One can use ping name instead to resolve to the IP address.

Then I tried to retrieve the client mac address, but this is not possible (as I know), unless I use an activeX, but this contains a little issue, the activeX will not run unless the site is in the trusted sites, and this method works only on windows OS since it uses the WMI (since it's a Microsoft component). If the computer is registered in the SCCM database you will be presented with the name in the Resources window. If there is no computer registered with that MAC address, the wizard advances automatically to the final window stating that there are no results. Simply go to Address Leases under the Scope and you can view both the client IP address and the Unique ID, which is the MAC address. If you have a wireless router at home, it will vary depending on the brand (Belkin, Netgear, LinkSys, etc). To find the MAC address on your Windows computer: Click on the Start menu in the bottom-left corner of your computer. Select Run or type cmd into the search bar at the bottom of the Start menu to bring up the command prompt.

I know I can ping and find the MAC address in my local arp table.
But what if a computer I want the address to is not started and can't respond to ping etc. and I cant reach it physically. Is there somewhere I can find this MAC address?
For example in routers or in DNS tables or something?

No you cant.Unless you have any mac-based rule on the switchport
Edit: dns reservations ( as you mentioned ) and dhcpd leases can work too.

you may be able to find it in the Arp Cache of a system that had discovered the computer, if you know the downed PCs IP address.
in Windows:
in Linux

If the computer have BIOS set up for remote start, you should be able to send 'magic packet' to it, to turn it on and then wait for its startup for network access.
Look for 'Wake on LAN'.

Asked a long time ago, but if you have access to a router in the network it might have a list of devices that are used in the network, some models show MAC address aswell.

Just got it from opening MMC - DHCP - IPV4 - your scope - Address leases after rwading through all the post.

One of my customers asked me to build this example query and I figured I would share with everyone, not just one company. it can be handy when you are doing OS Deployment testing and you need to look up a machine based on its MAC address to delete it so it becomes an “unknown computer” again. Keep in mind that in the ConfigMgr database, the MAC address is in the form of ZZ:ZZ:ZZ:ZZ:ZZ:ZZ.
select distinct SMS_R_System.Name, SMS_R_System.MACAddresses from SMS_R_System where SMS_R_System.MACAddresses = ##PRM:SMS_R_System.MACAddresses## order by SMS_R_System.MACAddresses
