I am running XP Pro on a 3 month old Dell box connected to a cisco 10/100 switch and I continuously lose my network connection. Sometimes I am asked to log in when trying access other drives on the network. I can usually log in as a different user, but cannot login with my normal log in. Often, it simply doesn't allow me access to other network drives.
The truly annoying part is that when I try to access a network resource, it takes about 2 minutes before anything happens. Then, I may be asked to log in and I may be granted access to the drive.
Usually, rebooting solves the problem temporarly, but only for a short time.
Does anyone know what might be causeing this?
Check the event log and see if there are any entries related to TCP/IP, DHCP, or network in general.
