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

or

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.
