Help Lost connectivity with PC and Server

brighteritltd
I have a site with 11 servers 2003 domain, with 2008 member servers.
Most deskptops/laptop are running xp with a company of windows 7 pro here and there. We have one 2003 server which seems to block pcs from accessing it.
If we then add an exclusion in the dhcp for this ip address that the servers on the pc and give it a new ip address it will connect fine. I have unistall av software and windows firewall is disabled just at a complete loss with this one

    So what you mean is that this specific 2003 server is not accessible from the network?

    You cannot access the pc from the server and vice a versa. This is a file and print server. All other devices can access the Server and connect to the PC.
    If you change the IP address of the Pc it will be able to access the sever once again.

    there are 100 pc's on the network and they all can access this file and print server but out of the blue one Pc will not connect ad the server cannot connect to the PC. Change the IP address of the PC and it can connect. There is nothing in the logs the av has been disabled. It always seems to effect the windows 7 pro pc. I have had to temp exlcude blocked ip's from the dhcp range till i get to the bottom of it.

    Don't know if this is relevant to your situation, but it might help...

    In server 2008 and Windows 7, you MUST leave the Windows Firewall *service* running, even if you don't want the firewall. If you turn off this service, you will be unable to browse shares or pings on that machine.

    This is different from XP and 2003, where you often actually needed to turn off that service, because it continued causing problems even when you turned off the firewall. I know several IT teams that ran in to this, because their "best practices" had evolved to actually disabling that service via a group policy prior to Win7 / 2008.

    We have run into this before but the strange thing it doesn't effect the other 10 servers which are accessible.

    Just curious, check the Nic card sleep/power saaving settings, try disabling them
    just a stab in the dark here

    Power management off tend to turn it off by default.
