I have HP core i5 laptop windows 7 pro 64bit sp1. since last three days I am not able to connect to my windows 2003 sbs sp2. I can ping or even can establish remote desktop connection. Earlier I was able to access shared files on the server. The rest of the machines (all windows xp pro) in the network are able to access the server. I have tried all the possible solutions. (flushing DNS, renewing IP etc.) My DHCP is handled by router and not by the server.
