Dot Net Framework 3.5 SP1 Full Download

Just try and find this anywhere on Google!!!  What a mess.

Anyway, I’ve found the correct download.  btw, dotnet35.exe is NOT the correct download.  You can install it, but then when you do a Windows Update, yet another .Net 3.5 SP 1 update will be there, just as big.

The correct full install can be found in the “Microsoft Update Catalog“.   Do a search for 951847 and all the 3.5 SP1 downloads will show up.  It’s a bit confusing because there appear to be two identical XP x86 installs.  I think they’re the same.

When you download it, you get a folder with the following files:

The largest is the full install.  The others are merely updates if you already have 2.0 or 3.5 installed.  More confusion here with the filename including “IA64_AMD64″ which makes it look like a 64-bit install.  But the file names begin with “X86″ so they’re not for x64.

Here’s a direct link to the catalog page:

Update: This update doesn’t seem to work either. I still get the .net 3.5 SP1 220+MB patch required w/Windows Update after installing this one. I have no idea how to properly install this patch without going through WU.

Vista – no IP from Comcast router

What if your Vista computer can’t get an IP address from a non-Microsoft DHCP server?

At my client’s sites, I’ve run into an issue twice now with Comcast’s “Business Gateway” cable modem from SMC Networks.  Vista refuses to acquire an IP address from the modem’s DHCP server.

It turns out to be a modification in the operating system’s DHCP Broadcast flag setting.  It changed from XP to Vista, from being disabled to being required.

The fix is pretty simple, once you find it:

In the registry,

Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}

In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.

On the Edit menu, point to New, and then click DWORD (32-bit) Value.

In the New Value #1 box, type DhcpConnEnableBcastFlagToggle, and then press ENTER.

Right-click DhcpConnEnableBcastFlagToggle, and then click Modify.

In the Value data box, type 1, and then click OK.
