Error Message: The Network BIOS Session Limit Exceeded (297972)

The information in this article applies to:

Microsoft Windows 2000 Server
Microsoft Windows 2000 Advanced Server

This article was previously published under Q297972

SYMPTOMS

When you access a Web site or a File Transfer Protocol (FTP) site, you may receive either of the following error messages:

The network BIOS session limit exceeded

550: The network BIOS session limit exceeded

CAUSE

This behavior can occur if Internet Information Services (IIS) on Windows 2000 uses a mapped drive for a Web or FTP site rather than a universal naming convention (UNC) share.

RESOLUTION

To work around this behavior, use UNC connections to the file server instead of mapping a drive.

STATUS

This behavior is by design.
