Windows 2003 Server NIC help

Dell Power Edge T310
windows 2003 R2 Enterprise 64bit edition sp2

Dual network adapters

both internal Broadcom Bcm5716c net xtreme II driver dated 12/28./2009 version 5.2.17.0

 When I set the properties of the ip interface on the network adapter I set the ip address default gateway and sub mask plus DNS and Wins entries, so I set the option to manually define the problem is when I go back to check the settings via the properties the properties window show obtain ip address information and al the entries I entered have disappeared.
If I do an ip config /all all the information I setup is there even after a restart.
I checked the registry and the values are there
So why is the network adapter properties not showing I have several other windows 2003 R2 servers they are standard 32bit and they work fine network adpater driver issue?

Any ideas

thanks

Tom
