We have Windows 2012 DC and windows 7 workstation. In our Active Directory we have and OU called workstations, within that OU we have a sub OU called Curriculum and again within this OU there is another OU called ICT4.
There are 20 PCs within this OU and when I login as a staff into these PC the internet opens fine, At the same time when a student logs in, I get the webpage displayed as shown in the attached snapshot. I am not sure how this page is opening rather than Google. We have a IE10 GPO and have set Google as the home page for the students.
There were few GPO attached to the ICT4 OU and I removed all the GPO and I did a gpupdate /force and still get the same error.
There are ICT 1, ICT2, ICT3 OUs within Curriculum OU and within each OU there are 30 PCs .
When I login as a student on any of the PCs within these OUs (ICT 1, ICT2, ICT3) google home page loads successfully.
To test I moved a PC (ICT1-PC2) from ICT1 OU to ICT4 and did a GP update on the DC and ICT1-PC2 and the internet works fine on this PC.
So not sure what is happening on other 20 PCs located within ICT4 OU.
Please suggest how to trouble shoot this problem. Any help much appreciated.
Thanks in advance.
