Vista - Vista Limited Connectivity Issues due to update.

I've a few Dell optiplex 760's and a few optiplex 755's that have Vista Business x86 installed and that are having issues with limited connectivity due to a update. There was a simular thread at one point but there was no info supplied as to what the solution was. I would like to know which update it is that is managing to pass through my WUS server so that I can block it from being sent out. Sorry to dreg up something so old but we just recently started having these issues last month. I have noticed that if I uninstall SP1 for Vista it will solve the issue but the issue didn't happen until well after the SP1 patch came out. I've checked several sites and still have come up with no answer. I guess I will uninstall these updates as suggested above but, if I could get an answer before my computer becomes super vulnerable again that would be even better.

Also, as an interesting side note...
This update seems to be messing with anything that has to do with DNS and hosting services. Also, the internet is unaffected and the network connectivity shows that I have Limited LAN access but no WAN access.

Thanks for everything ahead of time. Hope the extra information helps.

I don't know which update is responsible for that. In some cases, after
installing a update, you may need to install a new driver for the NIC or
firmware for the router. Please post back if you find it.
