    I have a machine running Windows Server 2003 and IIS 6.0 for Web and FTP
    hosting. Last Friday I installed service pack 1 and connectivity stopped.
    From inside my network i was able to access the ftp sites and the web sites
    running on that machine and everything seemed ok. Coming back now on Monday
    I have learned people outside our network canot access anything on that
    machine. After some reading I found that SP1 installs the windows firewall,
    thinking that it may be the problem I tried to check its settings only to
    find that it was not running at all. I checked with our ISP and although
    they too could not ping the address they did not show any problems with
    their network. As a last ditch effort to at least get things back to a
    running state I uninstalled service pack 1 and now everything is running

    Does anyone out there know any current issues with SP1 that may have
    caused my problem or has anyone delt with this issue before and could offer
    some advice?

    Thanks for the link. However, that really only confirmed what I already
    knew and that is......many people are experiencing this same problem.
    Like the people in that thread I too have 2 separate NICs connected to 2
    separate LAN/WANs. One is connected to my internal network which uses my
    internal DNS server address and one is my live IP which serves the web pages
    and points to my ISPs DNS addresses. One thing I noticed about my problem
    that was never mentioned in the thread is that IIS was serving the pages to
    anyone on my local network. The problem occurred when someone NOT on my
    local network tried to contact the site. It was because of this I figured
    IIS was not the problem but was something occurring at the network level and
    was blocking IPs. It was then I realized that SP1 installed a firewall but
    that wasn't even activated. Just for giggles I activated it and looked at
    its configuration and left it activated but turned off. Even still the
    pages could be seen by only my local network and no one else. I am only
    left to believe that SP1 installs some process that acts like a firewall and
    blocks addresses that are more than 1 hop away from the machine.

  3. I am having a similar problem and one other thing I noticed is that when the
    issue is present (ie. you haven't rebooted or disabled and re-enabled the
    adapter) the gateway disappears from the network configuration according to
    'ipconfig /all' but all local subnet traffic functions as normal.

    I posted in the thread mentioned above that I too am experiencing this
    problem but with the added twist that both of my NICs indeed use the
    same gateway address which will hopefully start getting people away
    from the idea that it can't work due to conflicting gateways...

    Also, I have the same experience in that I can access the sites on the
    local subnet but not from anywhere else. For now I am using the repair
    connection option and it brings everything back online just fine.
    Unfortunately, I need to do that way too often for it to be all that

    Has anyone been able to get Microsoft to admit this is a problem and
    that they are working on it? I'd rather not uninstall SP1 and then just
    have to reinstall it again in a couple of days if they are indeed
    working on a fix...

    Interesting note that ipconfig /all is showing the gateway as
    non-existant while this problem is being experienced. Hopefully someone
    at Microsoft will patch this up quickly...anyone wanna take bets?

  6. My workaround (until acknowledged by Microsoft as a problem and a solution provided) is to use a scheduled batch file that uses the "repair feature". I was tired (and I do mean tired) of getting up anywhere from 1:00 am to 3:00 am just to repair the connection. My scheduled job runs for 8 hours daily beginning at 12:00 AM since this anomaly would occur anywhere in that timeframe.

    My batch file does the following:
    ::Flushes the ARP cache.
    arp -d *

    ::Flushes the NETBios cache.
    nbtstat -R

    ::Flushes the DNS client resolver cache.
    ipconfig /flushdns

    ::Reregisters with WINS.
    nbtstat -RR

    ::Reregisters with DNS.
    ipconfig /registerdns
    ***Just make sure your Domain Group Policy or Local Policy gives the user right "logon as a batch job" for the account issuing the scheduled job or use an account that has that right.***

    I was running a very similar script...I got the idea from another
    thread (not sure if it was you or someone else that suggested it).

    Anyway, I was still losing connections way too often (as much as every
    10 minutes). It was beyond annoying. Both of my IPs were on the same
    subnet so I was able to move them onto just one NIC. Since then,
    everything has been fine.

    I still would like MS to release a hotfix to truly resolve the problem,
    but at least for now my server is stable again.

    I'm hoping someone will post back soon saying they've heard a fix is in
    the works...
