Hello, We have a Windows 2003 SBS Server (DOMAIN) in our company. Also there is another Windows 2003 SBS Server which has a Fortigate Firewall device connected to it. There are approx. 25 computers in the company. There are 3 computers running Windows 7 Professional. All of the other computers are running Windows XP. Only these 3 computers running Windows 7 Professional started to have a connection problem. The details are below. - Suddenly the connection to the server which is the domain provider has been lost. We can't connect to the files on this server. Connection to the exchange server has been lost. - Also it is not possible to open a page in Internet Explorer. - We can't ping this Windows 2003 SBS Server (Domain). But we can ping all other computers and the other Windows 2003 SBS Server. - Also nslookup command doesn't give us the domain address. - But the ethernet adapter is saying that it is connected to both serve and internet. "Currently connected to the ....(server name) and internet access" - But strangely Skype is running without any problem. - All of the other XP omputers doesn't have a problem. Only these 3 computers with Windows 7 have the problem. - These Windows 7 computers are connected to the server via wired ethernet switches. - All the Windows 7 computers and the server is fully updated. - We also reinstalled the ethernet adapters on the Windows 7 machines. Event viewer in the Windows 7 computers say that; "Name resolution for the name ........ timed out after none of the configured DNS servers responded." We tried all the commands such as ipconfig /flushdns, also release, renew, etc. on the Windows 7 computer. None of them helped. We found a temporary (for a couple of minutes) solution for the problem from the Domain Server. - On the Windows 2003 SBS Server, we cleared the cache of DNS and restrted the DNS service. - Repair the connection of ethernet adapter connection on the Windows 2003 SBS Server. But after you do that the problem is solved for a limited time. The same problem appears after a couple of minutes. It seems that there is a problem with the connection between Windows 7 computers and the Windows 2003 SBS Server. Maybe a compatibility issue. We installed one of the Windows 7 computers 8 months a go. The other Windows 7 machine 3 months a go. This problem started a 2 months a go. After a week struggling with this issue, we couldn't find a solution. Then suddenly the problem disappeared. It doesn't seem a problem in the Windows 7 machines. It seems a compatibility issue in the Windows 2003 SBS Server. Then a couple of days ago it started again and we can't work now. It is a strange problem. If anyone can help, we'll appreciate it. Thank you. Best regards, Taylan

Hi Taylan, are you still here? I'm having the same problems, and no one is able to help me out, can we get in contact and see what similarities we have here?? Thanks.
