You set the Configure Slow Link Speed Group Policy so that networked computers use offline files when those computers access a network share over a slow connection. However, Microsoft Windows XP-based computers go offline and use the Offline Files feature even when the network to which these computers are connected has sufficient speed and bandwidth available.
Note You experience this behavior even if you set the following registry entry to disable Offline Files on a slow link:
Value name: GoOfflineOnSlowLink
Value type: REG_DWORD
Value data: 00000000
This problem occurs because Windows XP does not correctly calculate the network throughput over a TCP/IP connection. When TCP reports the network throughput in this situation, no averaging is performed against the reported network speeds. Instead, TCP reports only the throughput of the most recent send operation. Therefore, the reported network speeds may greatly vary.
