  1. I have a workstation that won't see the network. This problem is intermitent. sometime during the evenings this guy can login fine, but almost always during the day he can't. I've changed NIC's, Patch Cables, Reinstalled his network stuff. I've even moved the computer to ensure the switch wasn't mac filtering or anything. Anyone have any sugestions. Its Windows XP.

    give us something to work with --- how many subnets, mfg of the
    routers/hubs/switches and how many users share this subnet with the effected
    system?
    Is it only one system with this problem?
    I assume you have a Domain Controller / LDAP implementation -- what's the
    network loading?

    There is only 1 subnet, this is the only computer affected. I have Windows 2003 SBE running on a dell server. It is a 3Com switch and there are about 13 users in total. We are licensed for about 20 users.

    first action would be to update the firmware in the router AND the driver
    of the NIC.

    They only device they have doing any routing is thier internet gateway. I updated the drivers on the NIC already and even installed a new NIC of a different brand.

    Are you using static IP's?

    Why do so many people ASSUME that static is different than DHCP?
    The lease period can be weeks and thus it only gets refreshed at the end
    of that time.

    DHCP is no better or worse than accessing your DNS; a timeout in either one
    will result in the necessity of a retry. Heck, all day today I've had a massive
    connectivity problem which is located in Los Angeles, CA as 61% of the traffic
    is getting lost, eg:
    Code:
    9   30ms    43/ 100 = 43%     4/ 100 =  4%  te-3-2.car2.LosAngeles1.Level3.net [4.71.36.73]
                                    0/ 100 =  0%   |
     10  ---     100/ 100 =100%    [COLOR="Red"]61/ 100 = 61%[/COLOR]  ae-32-54.ebr2.LosAngeles1.Level3.net [4.68.102.126]
                                    0/ 100 =  0%   |
     11   57ms    47/ 100 = 47%     8/ 100 =  8%  ae-3.ebr2.Dallas1.Level3.net [4.69.132.78]
    
    it's just the nature of the Internet :)
