Brand new installation of Windows 7 Home Premium (32 bit) on a Dell Optiplex 755, when I first boot the system, the following gets assigned:

 

IP Address: 192.168.1.116

Gateway: 192.168.1.1

DHCP Server: 192.168.1.1

DNS Server: 192.168.1.1

 

I can ping the server and any other device on the network but there is no Internet access on the system unless I disable the network adapter and re-enable it.

 

Intel 82566 onboard NIC

 

- uninstalled device & deleted drivers & rebooted

- re-installed drivers (same issue)

- changed DNS to Google servers (8.8.8.8 & 8.8.4.4) & rebooted (same issue) - set to auto again after

- assigned a static ip of 192.168.1.201 & rebooted (same issue) - set to auto again after

- set speed of the NIC to 100 MB duplex & rebooted (same issue) - set to auto again after

- disabled all startup items via msconfig & rebooted (same issue) - enabled all used startup items after

 

Any suggestions would be appreciated.

Did some more research and saw a few references to the Apple Bonjour service, tried disabling the service and rebooted, the network came right up.

 

Somehow the "new" installation of Windows 7 on the refurbished Optiplex 755 had iTunes and Quicktime (and NetZero) preinstalled.  

 

Uninstalled all Apple software (Bonjour Service, Software Update, iTunes, QuickTime).  

 

Double checked the services and the Bonjour service was removed.

 

Installed the current version of QuickTime & rebooted, network still comes right up.

 

The end.

Glad you resolved...BTW...of the apps you mention...the only one which, historically, has not created system problems for some users...is NetZero, IIRC.

 

Happy computing :).

Bonjour is a nasty networking nightmare, good job pinpointing it. It's a "remove on sight with prejudice" application for me.

 

:thumbsup2:

 

Just to share a little story. We have a guy in our company who decided not to use the printer detecting/installing software that we wrote for our network, but instead decided that Bonjour was a better option. :bubbles:Then rather than using the ready to go installers decided to use a driver detector to download and install the drivers/malware that he thought he needed... sigh.
