We are running Win98 SE. Our developers are writing a program and need to decrease the timeout for TCP. How is this done?

This parameter determines the number of times TCP will retransmit a connect request (SYN) before aborting the attempt. The retransmission timeout is doubled with each successive retransmission in a given connect attempt.

Registry Settings:
Key:[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
Value Name: TcpMaxConnectRetransmissions
Data Type: REG_DWORD (DWORD Value)
Data: 0 - 0xFFFFFFFF (Default = 3)

This parameter controls the number of times TCP will retransmit an individual data segment (not connection request segments) before aborting the connection

Registry Settings:
Key: [TcpMaxDataRetransmissions]
Value Name: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
Data Type: REG_BINARY (Binary Value)
Data: 0 - 0xFFFFFFFF (default = 5)
