Windows 7: Win7 machine at work has error Connection doesn't have a valid IP conf

Win7 machine at work has error Connection doesn't have a valid IP conf

One Win7 machine on our work domain can only connect via wireless adapter. Realtek NIC card gives error "Connection doesn't have a valid IP configuration". SBS2003 server handles DHCP (correctly for all other machines in domain). I've read several threads here but nothing seems to work. Bonjour off, ICS set to automatic - when i try to start manually it starts then stops.
Win7 thru NIC adapter sees "unidentified public network" and has no internet connection. Wireless is too slow and need to figure this out.

Try to manually enter the Default Gateway in your Windows 7 Network Adapterís IPv4 settings instead of Auto assignment, it's some sort of bug in Windows 7.

Please let us know if it works or not, then we'll try a diff tactic.
