I mistakenly uninstalled the "client for Microsoft Networks".?

You're in luck, since this is a simple fix.

First, restart. The client won't show up until you have rebooted your system.

Next, go back to your LAN properties and click on the "Install..." button. Double click on "Client" and choose "Client for Microsoft Networks." Click Ok and reboot your computer.

Click the start, control panel, network and dialup connections.

Right on your Network Connection and select the properties tab.

Click the add button then the client list.

Select Client for Microsoft Networks and install.

Good luck.

In network connection propertys choose install, and select client for microsoft networks. Make sure you have the os install disk.

hmm , this is really cool information... and whenever it happens that I am sure that i am not be tensed or would not be searching for this solution for couple of weeks :P
