## SYMPTOMS

In Windows NT, using an Open command in FTP with no (TO) entry causes an exception error in FTP.EXE.

## CAUSE

When the FTP service receives the OPEN command, it is trying to open a service (virtual port) to another computer. It is expecting either a host server name, or an actual IP address, such as 129.05.123.22. By providing nothing at the (To) prompt, you should receive an error message stating that the FTP connection timed out because it could not find the host server you specified.

## STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.1 and Windows NT Advanced Server version 3.1. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
