Files Are Not Posted Using FTP "PUT" Command through Microsoft SOCKS Proxy Service

ID: Q233285

The information in this article applies to:

Microsoft Proxy Server version 2.0

SYMPTOMS

When you attempt to use the FTP "PUT" command using a SOCKS 4-compliant FTP client through Microsoft SOCKS Proxy Server service, the file is not successfully posted to the FTP server. There are no errors associated with this symptom, except that the file does not exist after uploading.

CAUSE

This problem is due to the SOCKS server always performing a hard reset on the Internet socket closure in order to save time. This, in turn, causes the FTP server to reset during the PUT command.

RESOLUTION

To resolve this problem, obtain Microsoft Proxy Server 2.0 Service Pack 1. For additional information about Service Pack 1, please see the following article in the Microsoft Knowledge Base:
