SQL Server Virtual Server IP address Modification

Due to customer application changes, you need to modify the network structure and firewall settings. In this process, the SQL server cannot be bound to the listening port after the IP address of the SQL Server server is directly modified.
In this case, the IP address of the SSN server in the firewall must be modified to meet the customer's application requirements. To ensure that the server accesses the server by using the previous IP address, port ing is required. SQL Server is installed on a cluster server in the form of a virtual server. It has its own name and IP address. There is no problem in modifying the IP address of the cluster server, but after modifying the address of the SQL serveer virtual server, the port 1433 cannot be bound. Through the http://www.eventid.net to find error information 17055 to know SQL Server Virtual Server can not directly modify the IP address, SQL Server2000 needs to use the installation disc to modify, according to The kb244980 provided by the modification method to modify or not, it is estimated that it cannot be modified after modification. So I had to delete the SQL Server and reinstall it.
