Are you referring to Static IP address reverting back to DHCP? If so you can follow these steps. The NIC Configuration appears to Revert back to DHCP  NOTE: This process works for Windows Server 2003, 2008, and 2008 R2.   The Issue:   a.       A static IP address is set, but the NIC shows “Obtain an IP address automatically.”   b.      Running IPConfig /All shows the static IP address.   c.       The Registry shows the static configuration under HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}  What to do:   a.       Remove the bad configuration from the Registry.  How to do it:   a.       Start à Run à RegEdit   b.      Navigate to: HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Control\Network   c.       Delete the Config key   d.      Click Yes to delete the key   NOTE: Microsoft KB 937056 recommends rebooting the server at this point. If the following steps do not resolve the issue, perform the above steps again, except this time reboot the server instead of performing steps E-H.  e.      Open Network Connections  f.        Right-Click Local Area Connection  g.       Select Properties  h.      Click OK  Note:    This process rewrites the Config key without requiring a reboot.  i.         Reference:  i.          support.microsoft.com/.../937056  ii.       “The Internet Protocol (TCP/IP) Properties dialog box displays the default IP address settings after you manually configure a static IP address in Windows 2000 Server or in Windows Server 2003”
