Lan connectivity problems
Posted on 2007-10-04
Hello, we have been experiencing several lan connectivity problems in my company for about the last two months. More specifically, most users randomly lose their connection to several servers throughout the day. Also please note that the connectivity problems occur only with one server at a time. We have Windows 2003 Active Directory with DNS and WINS server, several Windows 2000 and 2003 servers (these servers are domain members) and Windows 2000, Vista and XP clients. As a firewall, we are using Endian Firewall. We have already checked that it is not a network hardware problem(switches,cables). The event logs of the servers haven't any suspicious entries. We also have checked each machine for viruses. Please help!!!
