Windows 2000 Does Not Use Configured TCPWindowSize Registry Parameter When Accepting a Connection (263088)
The information in this article applies to:
- Microsoft Windows 2000 Server
- Microsoft Windows 2000 Advanced Server
- Microsoft Windows 2000 Professional
This article was previously published under Q263088 SYMPTOMS
Windows 2000 does not use the configured TCPWindowSize registry parameter when accepting a connection (SYN-ACKing) if you configure the parameter per interface and if the value is equal to or greater than 64240 (it uses a window size of 17520 instead, if you are using Ethernet).
CAUSE
The TCP connection accept functionality does not correctly parse the window size if you configure the parameter per interface.
RESOLUTION
To resolve this issue, set the TCPWindowSize value globally or use a value smaller than 64240 (this value is a multiple of the Ethernet Maximum Segment Size).
STATUS
Microsoft has confirmed this to be a problem in Microsoft Windows 2000.
