Cisco 1841 Router Help with Webserver

[beigemonkey]

So heres the situation:
I can't browse to any of the websites I am hosting on my servers internally. I can browse to it from another network externally. If I add a record in the DNS mapping to the internal IP then it works perfectly. Is there anyway of doing this without adding a DNS record. Any help would be greatly appreciated!

Equipment:
Cisco 1841 router
Windows Server 2003: DNS/DHCP
Windows Server 2008 R2: IIS
Windows 7

Windows Server 2003 has a static IP of 192.168.0.2
Windows Server 2008 R2 has a static IP of 192.168.0.101

interface Ethernet0/1
ip address 64.102.2.40 255.255.255.0
ip nat outside

You can try the below settings under global config mode ie. not under an interface:

ip nat inside source static tcp <internal IP mail server> 25 interface fa0/0 25
ip nat inside source static tcp <internal IP web server> 80 interface fa0/0 80
