Windows 7: Loosing Static IP address

Hi,
Since Friday, a few computers running Windows 7 Pro have lost their static IP address.
When checking the Local Area Connection / Properties / Intenret Protocol Version 4 / Properties / the fields IP address and efault gateway are blank - despite the fact the "Use the following IP address" is selected".

Re-entering the static IP address does fix the issue but I don't understand why this is happening.

I am running BitDefender End Security Point on each machine.


The issue does not happen on all the Windows 7 machine.

A few users have reported an automatic installation of a Windows update - then a reboot - before the ip address issue occured. But I cannot confirm this point for each case.


Has someone seen this before ?

Just wondering, what range are your static IP(s) in and do you know if there is a possible conflict with your DHCP scope ranges?

Range: 192.168.1.x
Static from x=1 to x=119
DHCP scope (only one) from x=120 to x=232

Ok, after getting a few more like this and checking the W7 event logs, it seems that the nic driver gets updated and does not always keeps the network settings.
I have followed 'rindi' advice by using reservations in the DHCP server. This is indeed more logical and practical.
Thanks
