When you use the gethostname function in Windows NT, it does not support the ability to use alternate computer names for the computer.
The gethostname function returns the node name instead of the cluster name in the network name resource.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Microsoft has confirmed this to be a problem in Windows NT Server, Enterprise Edition version 4.0. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
The change that was made in GetComputerName to support alternate computer names has been added to gethostname. GetComputerName checks an environment variable. If that variable exists, GetComputerName returns its value instead of the real computer name. The change was made to keep applications from breaking in a cluster.
