SBS2003 cant connect to network after power supply failure.

I have a SBS2003 that has been working for years.  Had the power supply fail a couple of days ago, put one in from another box that works (the server is old and couldnt find a new one).  I'm getting ready to switch to a newer server with SBS2011, but need this one to run for another week.  

Now this one cant connect to the network and i have all the computers on the network running on alternate manual IP addresses.  The server cant ping the router/default gateway.  

I have already (no particular order) -

- put another NIC in the server and tried that, disabling the first one
- run the internet connection wizard
- checked that the rest of the network can connect to the gateway and the internet
- switched to a different ethernet cable
- connected directly to the router
- switched ports that the sbs2003 is connected to on both the switch and the router
- the router seems to be working fine, I'm sending this through it
- can ping the server IP from inside the server
- can't ping the router from inside the server
- the configuration is the one with only one NIC

    where is your dhcp, is it the router or the SBS itself ? if its SBS try to enable the dhcp from router and check if you are able to receive auto ip.

    Yes, I can use the router for DHCP, did it for a while when I was getting the new power supply.  As far as I know, the DHCP needs to work from the SBS2003 when it is up and running, something about active directory.

    The SBS2003 has been the DHCP.

    Yes its in DHCP , better you go to to start menu ---> programs ---> administrative tools ---> dhcp and expand ipv4 , right click and stop the dhcp and let the router take care of the dhcp and try if it works.

    ok, turned off DHCP on the SBS2003 (had to turn off DNS first), no difference.

    couple of things I forgot to mention, the message I get when I try to run repair from the Network connection is
    - "could not compete ARP cache could not be cleared"  
    - when I ping the router i get "destination host unreachable"

    the DCHP on the router appears to be working fine, tried the internet from a workstation, get internet and network fine.  Just the sbs is not connecting to anything.

    Do one thing, try upgrading to the latest service pack of windows SBS2003 or if you have any previous Service Pack installed , uninstall and re install it again plus refer to the following link below :
