I have this problem going on on some computers on my network...if you go to the network neighborhood and try to list the entire network...the domain name will show up but no computer listed underneath...if I reboot the computer they will show up...does anyone know what might be causing this?

Can you provide more details? What operating system are these computers running? Are there multiple domains? Are you logged into the domain or the local machine?
Also check to make sure Windows isn't powering down your NIC (which is the default) to save power.
On Windows 2000/XP, right-click "My Computer" > "Manage" > "Device Manager"
Double-click on "Network Adapters" and right-click on your NIC. Choose "Properties" and click on the "Power Management" tab. Uncheck the box labeled "Allow the computer to turn off this device to save power." Click OK, close the MMC, and reboot.
Normally, if there's no activity over the network on that device (from your machine) for a certain period of time, Windows will "shut off" the device.
