Adding second NIC stopped network working

i decided i wanted to add a second nic to my server.
i have on that is 100mps but i have now added a gig one

the problem is that i changed the ip of the original card to a spare ip and put the new one to the original cards ip.

i thought this would just work, however it seems to of lost all of its networking.  although all the services run , i cannot see anyone, and vice versa.

what could the problem be.

i changed them back but i seem to have completely messed it up as this doesn;t work either now

I would jot down the config for original nic, physically uninstall it or disable it in the hardware manager. Install the new card and bootup. Does the card get a dhcp address? If yes, can you see the network/internet? then change the settings to match the original nic. In the network connections setting, it could be listed as Local Area Connection 2. Rename it to Local Area Connection. If there already is a Local Area Connection from the previous nic delete it.

sorry what i was trying to say is that i have already donethis and it has gone wrong.

 i do not use dhcp but i have no experience with it.  i kind of ened up with this job, so i do not know what to do.

Well, the next step I would do is go to another computer that is using a static ip address and copy its information. compare it to what is setup in the new nic. If you go to Start > Run > cmd  click enter
at the dos box type
ipconfig /all
on both pc's check to see the differences.
ip address both in the same subnet?
192.168.1.???
same subnet mask?
255.255.255.0?
Same gateway?
192.168.1.1?
Same DNS servers?
Same WINS servers?

Was this server handling any of these functions? DNS, WINS?

Checkout these pages. I would put a pointer question to this question in the Networking area of Experts Exchange. Sounds like your nic is fine, you just need help redoing the dns settings.
