Vista can't see XP on workgroup!

[Admiral Huddy]

Last night I was called out to install a small home-office network. One of the machines was an XP Pro machine and the three others where Vista.

Not a problem I thought but I couldn't not get the Vista machines to see or map a network drives from the XP machine. Vista to Vista where fine.

After about 20 odd minutes thinking it was a problem with privilages, a quick search on MS found this:

Layer Topology Discovery (LLTD) Responder (KB922120)

This soon got it working.

I've setup quite a few mixed PC on the same workgroup but first time I've come across this.

It's like they know there is a problem and using it to their advantage to get users to use WGA. This stuffs those users who don’t have a genuine license but at the inconvenience of those with. .

The discovery protocol should be a hotfix really.
