RAS Port Instance Names in Performance Monitor Are Corrupted

• Microsoft Windows NT Workstation version 3.51 Service Pack 2
• Microsoft Windows NT Server version 3.51 Service Pack 2

SYMPTOMS

Normally, the Remote Access Service (RAS) Port Instance names are displayed as COM1 and COM2. However, in Windows NT 3.51, Performance Monitor displays the RAS Port Instance names as "C" (without quotation marks).
