Boolwinapisetcomputername (

_ In lpctstrlpcomputername

);

There are certain requirements for computer names. The msdn explanation is as follows:

The computer name that will take effect the next time the computer is started. The name must not be longer than max_computername_length characters.

The standard character set parameter des letters, numbers, and the following symbols :! @ # $ % ^ &')(.-_{}~ . If this parameter contains one or more characters that are outside the standard character set, setcomputername returns error_invalid_parameter.
