ZOTAC Z68ITX-A-E Nic did not obtain IP

Hi all

I built a pc with mobo ZOTAC Z68ITX-A-E. it has two gigabyte NICs and Wifi. At home, everything work fine. I took my pc to work and connected it to wire network and I tried both of NICs. It did not obtain an IP. While I have another pc works fine, there is no problem with work network. Even I tried ping 127.0.0.1 and it work.

I am guessing the problem is from the driver!. But I removed it, and install it again. nothing happened.
I tried Windows troubleshooting. Also it did not solve the problem.

I am using Windows 7 Ultimate with SP1.

Please help me....

The BIOS version numbers I got differ from yours but your date suggests that it is the Factory delivered version. There was a new BIOS for your board released in september 2011, I suggest you upgrade and see if it fixes your issue. Good test btw to put in a separate NIC, I would have tested this as well.

Hello Almatrodi, there is a few things you can do:

- Have a look in the Windows Event logs and see if there is anything odd in the Application and System categories.
- Check the Speed&Duplex setting on the NICs, is it set to Auto-Negotiate? If so, try 100Mb full duplex instead.
- Check with your IT Department at work if there's some policy active that prevents unregistered/unknown computers (NICs) to access the network.
