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.



WORKAROUND
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To work around this issue:  Start Registry Editor (Regedit.exe). Locate the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VxD\MSTCP\Parameters

 On the Edit menu, click Add Value, and then add the following registry value:

Value name: GlobalMaxTcpWindoSize

Data type: DWORD

Value: (size in bytes)

 Quit Registry Editor.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
