Win7 systems not getting internet access on LAN
Posted on 2011-03-23
I'm having a problem with 3 Windows 7 clients on a customer's LAN. The server OS is Small Business Server 2008, so it's the DC, DNS, and DHCP server. Site router/firewall is a Fortigate 60B. Systems all connect through a 48 port Cisco Small Business Pro switch. The clients are a mix - 2 Dell laptops and a Lenovo desktop. Here's the symptoms users are seeing - they power on their system, login to the domain and have access to LAN resources (server shares, network printers, etc) as soon as they connect. They have no internet access initially but eventually they are able to get internet access...wait time for internet access is around an hour. I have the event log of one of the Dell systems and one of the first errors I see is eventid 1001 (error 0x79), unable to obtain an IP address from the DHCP server. Just prior to the 1001 error there is another entry with eventid 1003 (error 0x79) saying that the system wasn't able to renew its IP address.
This is something I've been struggling with for quite some time and thus far have not been able to find a resolution. If anyone out there can offer some assistance or ideas as to what might be going on...I've included these eventid's in hope that they may shed some light on the issue but I'm not sure they do or don't have anything to do with what's going on.
Thanks in advance for the help.
