Err Msg: "Could Not Set Printer" if Port Name Includes Comma

 Last reviewed: March 26, 1997
Article ID: Q142059
The information in this article applies to:
  • Microsoft Windows NT Server versions 3.5 and 3.51
  • Microsoft Windows NT Server version 4.0
  • Microsoft Windows NT Workstation version 4.0

SYMPTOMS

When you attempt to add a printer port in Print Manager that has a comma in the port name, the following error message appears: 

   Could not set printer: The specified port is unknown.

CAUSE

Currently, Windows NT does not support the use of comma's in port names. NT Uses comma's for separators, thus they are not valid for printer names or port names.

WORKAROUND

To work around this problem, rename and remove the comma in the port name.

STATUS

Microsoft has confirmed this to be a problem in Windows NT Workstation and Server versions 3.51 and 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
