Cannot start DHCP service on Windows 7 SP1 laptop

Greetings,

I have a Dell Latitude E6410 laptop running Windows 7 Professional.  Last night, I installed Win7 SP1.  And everything worked fine and I was able to attach to my home WiFi and browsed the Internet and connect to company VPN.

This morning, when I tured on the laptop, my WiFi said that I was connected to the network, but had no internet access.  Upon troubleshooting, I found that the laptop could not get an IP address from the DHCP server.  On further troubleshooting, I found that DHCP client service on the laptop was not running.  I tried to run it, but it failed with Error 1068: The dependency service or group failed to start.

In the Systems log, I see these two entries:

Log Name: System
Source:      Service Control Manager
Date:          3/2/2011 1:22:30 PM
Event ID:     7000
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      XXX-XXXXXX.XXX.local
Description:
The NetIO Legacy TDI Support Driver service failed to start due to the following error:
The system cannot find the file specified.


Log Name:      System
Source:        Service Control Manager
Date:          3/2/2011 1:22:30 PM
Event ID:      7001
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Computer:     XXX-XXXXXX.XXX.local
Description:
The DHCP Client service depends on the NetIO Legacy TDI Support Driver service which failed to start because of the following error:
The system cannot find the file specified.

The problem is that, as mentioned above, DHCP service is not running on the laptop and thus, laptop does not get a valid IP address.  If I put in static IP address, then I am able to connect to the local network and have internet access.

I have tried to download latest drivers for the wired as well as the wireless network adapters, but that did not resolve the issue.  And I still have the same issue when I log into Safe Mode.

Any ideas out there on how to resolve this issue?

Thanks for your assistance in advance.

Update on this issue:

It appears that installing Windows 7 SP1 somehow broke TCP/IP on this laptop.  Uninstalling SP1 resolved the issue and DHCP client services started working again.  I reinstalled SP1 and the same issue returned.

At this point, I am not sure why installing SP1 on this particular laptop caused the issue.  We have one other Windows 7 laptop that we installed SP1 on and this laptop is not experiencing this issue.

Uninstalling Windows 7 SP1 resolved the issue on hand.
