ID: Q186078

The information in this article applies to:

Microsoft Windows NT Server version 4.0

SYMPTOMS

Name resolution may fail if the NetBIOS name has an ASCII sixteenth character. The problem occurs with Microsoft Systems Management Server Remote Control service when trying to attach to a computer running the Remote Control server component. The problem occurs when the name is not registered with WINS, and DNS is used to resolve the name.

This problem may occur with any application using ASCII characters for NetBIOS name suffix.

CAUSE

Systems Management Server Remote Control service uses <0x43> (ASCII "C") as NetBIOS name suffix for Systems Management Server Administrators Remote Control tool.

While generating the fully qualified domain name (FQDN) to be resolved by DNS, the NetBIOS service parses the name incorrectly when the suffix is an ASCII character.
