Hi all, Problem #1: Like the title says, I cannot access my shares located on any server on my home network via the server name only via IP address. All servers are Server 2003 EE. This is only happening on my main PC (Dell PowerEdge SC430 w/ Win XP). All my other PC's it's fine. I reformatted and reinstalled XP SP2 the other night. In addition, I cannot remote desktop to those servers using their name. I have to use their IP address. Problem #2: Also, on my one server, when I browse to it (//svr-01) I do not get a prompt for username/password. I can automatically see ALL my shares, but I can't authenticate to access any of them (they are all protected). I can map a network drive and "connect as" which then gives me access to all the shares under that username/password. However, upon reboot of my local PC, I lose that connection. My local Win XP SP2 is completely up to date with every update, fix, patch. I am running Norton Internet Security 2007 w/ all updates as well. Thanks for the help.
