My network is a network of industrial data networks and Ethernet mixed. Because of the business needs, there is a primary domain controller in this network to pass industrial network data to Ethernet, while other two other workgroups on Ethernet (the domains needed for industrial data, In this network, three working groups can be seen, group A is actually a domain of two computers, and the rest of the computer is in other two working groups). I use the Active Directory and DNS resolution services in the domain controller in the A group. But the problem is that a finance server in the B group is always connected. In other words, the financial data client cannot find the financial data server after restarting, and must be entered from the client. Data Server (Enter // Services IP Address / D $ in the browser) After entering the network password dialog and verify it, the client can find the financial data server, otherwise the client will not find the SQL server. But my hybrid network has been used for nearly four months, and this problem is the day before yesterday. My financial data server is used by Windows2000 Server SP4 MSSQL2000, my client is Windows2000Pro SP4. Please advise you prawn. Xie Xian! ! ! /
