I try to setup networking with a fresh CENTOS4.4 installation. Upto now I have 20 installations, most of them FC3/FC4 and RHEL3. I noticed that the default gateway is not setup properly when using Centos.

Networking is setup done by using dhcp, and this seems to work OK. Problem is however that the gateway should be 192.168.101.2 and not 192.168.101.1 (does not exist). If I manually add the gateway, networking is OK:
Sounds like you need to fix your dhcp server so that it hands out the proper information.
Thanks Jim. That triggered the right thing. I had two servers specified in my dhcpd configuration:
option routers 192.168.101.2, 192.168.101.1;
option routers ip-address [, ip-address... ];
The routers option specifies a list of IP addresses for routers on the client’s subnet. Routers should be listed in order of prefer- ence.
All my other Windows and Linux boxes up to now don't seem to mind. I checked the routing on other boxes and they show up with both gateways (the old gateway was replaced a year ago..).
Again thanks, you pointed me to the right spot.
