Unable to Set the TCP/IP GlobalMaxTcpWindowSize Parameter in Windows 98

• Microsoft Windows 98
• Microsoft Windows 98 Second Edition

SYMPTOMS

When you set the GlobalMaxTcpWindowSize registry parameter for TCP/IP, it does not affect the global maximum TCP receive window size (GlobalMaxRcvWin) in Windows 98 and Windows 98 Second Edition.

CAUSE

This behavior occurs because the name of the GlobalMaxTcpWindowSize registry parameter is misspelled as "GlobalMaxTcpWindoSize" in the Windows 98 TCP/IP code.
