Lund, Sweden refuses to work around a Vista bug, so people who live there must choose between Vista and internet access. It's nice to see the right people being held accountable for a change.

Keep that shoe on the other foot for just a little longer. Imagine them having "support scripts" that travel through a KDE interface instead of Outlook Express or IE. Imagine them requiring Ubunto to install your access. In short, imagine all of the "standardization" Windoze enjoys being flipped on you.
In the free software world, users can edit a few well annotated text files to get the job done if they are given the proper information. That task is harder in Windoze because you must dig through several GUIs that don't tell you what to ask for in advance or ever.

As I understood it, the bug was this: Vista will only accept broadcast replies to DHCP requests. Any multicast response is discarded for security reasons (!?). So their solution was to put a DHCP server on every level of our network (for us, one for every 200 users) or switch to a network that relayed the broadcasted replies (ie: hubs). They also told us it wasn't a bug so they wouldn't issue a patch to correct it. There was a KB article on the issue but when we had users call MS support and ask them to walk them through applying it, we got a bunch of angry calls back to us saying MS refused to help them with it. We also talked to Cisco a bit to see if they had any idea what we could do to relay the broadcast but they never got us a solution.
So in the end, we told MS that we'd either need a better way to fix this or we'd just tell our users not to use Vista. They seemed okay with us telling users not to use it so we have. A few of our users still use Vista with a home router and that seems to work alright. Luckily, there aren't too many Vista users yet and when faced with the option of buying and configuring a router or buying and configuring Windows XP, they've decided on XP. So all in all, it wasn't that big of a deal.

I work for a networking company and a few months ago I fixed our BootP relay to be able to handle this.
If you read the DHCP RFC, you will discover that this broadcast packet is actually an optional part of the spec. Furthermore, it was designed for (at the time - circa 1993) LEGACY equipment that could not handle unicast responses.
Ie, I ask for an IP address, and because I'm a crappy old piece of hardware that can't handle it, I want the DHCP server to reply to me with a broadcast reply telling me my IP address. Normally such responce is unicast to your MAC address and everyone is happy.
Windows XP works fine and will accept a unicast reply. In Vista Microsoft had the brilliant idea that they should enable this flag by default - despite the fact that any modern computer should be able to handle a unicast reply - they could back in 1993 after all.
So yes, the fault is precisely with Microsoft for enabling an unnecessary and OPTIONAL part of the DHCP protocol by default, causing untold problems that could simply be avoided if they stuck to the XP way of doing things.

Vista has a new TCP stack, it would be incredibly stupid to implement such an ancient bug, especially when all earlier versions of windows worked correctly.
Infact, the vista TCP stack does support receiving of unicast packets, and yet microsoft still chose to use the broadcast flag without reason. That's why this ridiculous behaviour can be turned off with a simple registry entry. The broadcast flag is intended for TCP stacks which _CANNOT_ support unicast, it is absoloutely incorrect to use it as the default on a stack which can support it.
The broadcast flag is only intended for compatibility with very old TCP stacks (i cant think of any which requires it, and it makes sense that this legacy functionality was intended to be removed when you weren't using any of these legacy systems.
So, did this swedish ISP have any reason to believe that people would be connecting ancient TCP stacks to their network? If not, it makes sense that they wouldn't support this legacy flag.

1. There is one flag in DHCP protocol, the "BROADCAST" flag. The "Clarifications to BOOTP (RFC 1542)" gives a nice description of it's purpose (referenced from DHCP RFC2131).
2. Normally the server sends DHCP replies as unicast packets to a specific node.
3. It is suggested there are TCP/IP implementations unable to receive such a unicast packet before they have been fully configured, in which case they should set "the flag" to request that the server sends it's reply as a broadcast instead. Server should honor such a request. I guess such an implementation would configure their local MAC (or equivalent?) at the same time with their IP level settings, which might be a sensible thing to do in a simplistic single family (IP-only) network stack, which was designed before anybody thought of "auto-configuration" things like DHCP.
4. For some unknown reason, Vista sends DHCP requests with "the flag" set by default, even if it doesn't have said inability to receive unicast packets before being fully configured.
5. A DHCP server should honor such a request, though from reading the discussion here, I futher conclude that for various reasons, maintainers of certain servers and/or networks are unwilling to support broadcast replies to DHCP requests. At least in case of centralized DHCP servers this seems a reasonable decision.
Now, it's likely that MSFT has some purpose for setting the broadcast flag (other than pissing people up). So far this purpose is more or less a mystery to me. One possible reason I can immediately think of would be allowing a DHCP server to detect the presence of another DHCP server by monitoring DHCP reply broadcasts that somebody else sent (that could be useful for certain types of "zero-config" networking maybe?). But then again they might have another reason? Who knows.. maybe they wanna start selling DHCP relays? Or maybe they want Vista users to get static IPs?
Anyway, it doesn't seem like anyone is breaking the letter of the standard, as the DHCP requests Vista's sending are technically valid (although the flag isn't set for the specific rationale it exists for), yet the servers/networks/whatever aren't really required to support the flag either (although they "should").

I assumed there was some misconfiguration problem I was missing, Turns out it's a fundamental difference between the DHCP client in Vista and the one in prior versions of Windows. See this item from Microsoft: http://support.microsoft.com/kb/928233/en-us [microsoft.com].
The version of dhcpd I'm using is an old one (2.0). I thought about upgrading it to see if that would solve the problem, but since I wasn't planning on keeping Vista on the laptop, I didn't bother upgrading. All our other machines run Linux and don't have this problem.
I wonder what decision will be made in enterprises running Linux DHCP servers that introduce Vista into the workplace. Will they follow the Microsoft KB item above and "fix" the problem on every new Vista box they buy? Or will the replace the Linux DHCP box with Windows Server?
Re:Vista DHCP client and Linux (Score:5, Informative)
A client that cannot receive unicast IP datagrams until its protocol
software has been configured with an IP address SHOULD set the
BROADCAST bit in the 'flags' field to 1 in any DHCPDISCOVER or
DHCPREQUEST messages that client sends. The BROADCAST bit will
provide a hint to the DHCP server and BOOTP relay agent to broadcast
any messages to the client on the client's subnet. A client that can
receive unicast IP datagrams before its protocol software has been
configured SHOULD clear the BROADCAST bit to 0.
RFC1542 States
3.1.1 The BROADCAST flag
Normally, BOOTP servers and relay agents attempt to deliver BOOTREPLY
messages directly to a client using unicast delivery. The IP
destination address (in the IP header) is set to the BOOTP 'yiaddr'
address and the link-layer destination address is set to the BOOTP
'chaddr' address. Unfortunately, some client implementations are
unable to receive such unicast IP datagrams until they know their own
IP address (thus we have a "chicken and egg" issue). Often, however,
they can receive broadcast IP datagrams (those with a valid IP
broadcast address as the IP destination and the link-layer broadcast
address as the link-layer destination).
If a client falls into this category, it SHOULD set (to 1) the
newly-defined BROADCAST flag in the 'flags' field of BOOTREPLY
messages it generates. This will provide a hint to BOOTP servers and
relay agents that they should attempt to broadcast their BOOTREPLY
messages to the client.
If a client does not have this limitation (i.e., it is perfectly able
to receive unicast BOOTREPLY messages), it SHOULD NOT set the
BROADCAST flag (i.e., it SHOULD clear the BROADCAST flag to 0).
DISCUSSION:
This addition to the protocol is a workaround for old host
implementations. Such implementations SHOULD be modified so
that they may receive unicast BOOTREPLY messages, thus making
use of this workaround unnecessary. In general, the use of
this mechanism is discouraged.
If XP can receive unicast IP datagrams. why cant Vista? Either MS broke Vista or the TCP/IP stack is less functional than before. Either way, use of the broadcast flag is discouraged.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To resolve this issue, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps:
1. Click StartStart button, type regedit in the Start Search box, and then click regedit in the Programs list.
User Account Control permission If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
2. Locate and then click the following registry subkey:c es\Tcpip\Parameters\Interfaces\{GUID}
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servi
In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
3. On the Edit menu, point to New, and then click DWORD (32-bit) Value.
4. In the New Value #1 box, type DhcpConnDisableBcastFlagToggle, and then press ENTER.
5. Right-click DhcpConnDisableBcastFlagToggle, and then click Modify.
6. In the Value data box, type 1, and then click OK.
7. Close Registry Editor.
So Vista isn't (formally) going counter to protocol, it's just going counter to a 15-year old custom. Nonetheless, Vista *can* cooperate, it just needs to be told not to raise the DHCP BROADCAST flag. And yes, that route goes via a registry modification.

For some bizarre reason Vista expects the address returned from the DHCP server to be broadcast, instead of sent via unicast packet. This is permitted in the specs and supporting the broadcast flag on the server is suggested. ("SHOULD", not "MUST" in the spec.).
When researching this I found 2 network types which required this, Infinibad and 1394 (Firewire). It looks to me like Microsoft picked the one which would (theoretically atleast) work on all network types, instead of only on a few.
Of course, this is a typical bad decision as it means that responses from a DHCP server with a lot of Vista clients will flood the network with broadcast responses, but hey, they arent know for making good decisions.

If by "modern", you mean "at least 1 gig of RAM", I guess that works.
I have tried it on a machine with 512 megs of RAM. It was Home Basic, and it was loaded down with HP crap, but no matter how much I cleared away, it still took several minutes to do anything. And I mean anything. Control panel? Two minutes. Internet Explorer? A minute and a half. It was ludicrous.
And I am fairly confident it was the RAM, because it was paging like mad. I did plug in a USB stick and used ReadyBoost while I was there, and it did improve things, but not by much.
Now, I know someone who upgraded from XP 64-bit to Vista, and basically raves about everything about it, and I don't blame her -- XP 64-bit sucked. She realizes that was a mistake, should've stayed on 32-bit. But Vista 64-bit isn't bad (finally catching up to Linux' 64-bit support), and it's generally been solid for her.
She also has, I believe, some 2 gigs of RAM.
Her advice to me was, less than a gig of RAM? XP is faster. A gig or more? Vista is faster.
Which makes me wonder what the fuck it's using half a gig of RAM for. I have Kontact (Outlook-like app, so email, calendar, etc), Konqueror (web browser), two IRC clients, Kopete (multi-IM client), KTorrent (bittorrent), and a Windows game open in Wine right now, and it's using less than 600 megs of RAM. Vista, apparently, uses at least that much just to show you a desktop -- I remember it being a gig or so paged (I'm not kidding) with nothing open other than the task list. What gives?
It's not Aero, by the way. I've had Beryl on this computer before, and right now, it's running KWin with everything turned on, which includes some Beryl/Aero-like features (including real drop shadows and transparency), and that doesn't use a significant amount of RAM, either.
The issue is that when you play media, your download slows. And there is absolutely no reason for this, and versions of Windows prior to Vista are not effected, all the way back to 95, probably 3.1.
And I actually do have a PC that doesn't do that. It runs Ubuntu. It also doesn't slow down when downloading, even torrents, because they use so little of my resources (aside from bandwidth) that I can do pretty much anything I was doing before (unless it's online).
Where'd you get this information?
Last I checked, they hadn't even acknowledged it as a bug. They were still insisting that it had to be this way in order to not have the music skip. (Well, guess what? My music doesn't skip even when I'm transferring stuff over Gigabit. Novel concept, I know.)
People complain that Linux is focused on throughput and not latency -- that is, that it'll make my desktop lag just so that background compile can run 2% faster. Here's a clear example of why you don't want to go too far the other way, though -- playing any audio at all on Vista slows your network down by 10%.
It may not be enough for you to notice, as that's still probably faster than your Internet. Probably. But it doesn't make it any less of a bug, no matter what Microsoft says.
That is and has been true, and occasionally various users find it better enough to make the switch. (Not all users do, obviously, and some never will.)
Being able to download fast while playing media is unarguably better than lagging. Being able to play a multiplayer
