Vista/Win7 password issue

    I have a weird problem with Windows 7 or Vista laptops accessing the internet through my Linksys WRT54Gv3 running Tomato 1.28. Whenever I try to access the internet, I get continuous popups with the title "Windows Security", saying "The server (my domain name) at (my router name) requires a username and password". But then I can hit cancel and everything's fine - until the next time, and the box pops up again.

    Note that I am NOT trying to access the router admin page or anything; this just happens any time I try to access anything on the internet. I can put in the admin password and save the credendials to keep the box from coming up, but I don't WANT every laptop on my network to have the admin password.

    I'm using the Linksys-served DHCP without any kind of proxy.

    This seems to only happen on Vista and Windows 7 laptops; XP doesn't doesn't do this. Nor do I have trouble with an iPhone, an iPad, or a Wii.

    I've scoured the internet and can't find a solution. Any help?

    Are you running pixelserv? Had the same problem for awhile. You need to move the web gui to another port to fix it.

    Nope, not using pixelserv.

    Turns out it's not specifically a Vista/Win7 issue, it has more to do with IE8 (at least). It does the same thing with IE8 on XP, but not Firefox. It's just worse on Vista/Win7 since those versions can make a lot of HTTP requests behind your back.

    The problem goes away if you go into Internet Options|Security|Custom Levels|User Authentication|Logon and set Anonymous Logon.

    The issues with this solution are that (a) I don't want to have to monkey with the settings for every new computer that comes along, and (b) I don't really understand the security ramifications of doing this.

    This doesn't happen with the default settings on the regular Linksys firmware, so it's either something in my configuration, or something in Tomato itself. I'm assuming the former, since I think I'd find a lot more info about it if it was that widespread.

    Do you have the WINS service enabled on the Tomato router?

    I don't think so, but I'm not sure where that is configured ... the only WINS-related entry I can find is on the is Basic|Network page, WINS is set to

    I was just trying to think of a daemon on Tomato that would be prompting for a username/password. I'm not very familiar with Tomato, so I can only guess.

    If it only does it when you're browsing the internet... that would at least involve DNS and NAT. What is set for the DNS IP on your clients? Is it the IP of the Tomato router or the IP of the actual DNS server?
