Assuming you have the security set correctly, there is little need to limit the number of connections. A careful balance must be made between the: HKLM\System\Current\Services\LanmanServer\Parameters\Autodisconnect (which is the timeout (in minutes, I believe) before the server axes NetBIOS connections) and the sharepoint maximum connections. If you limit connections to the sharepoint, make sure autodisconnect is enabled and that it is a relatively "small" value as to avoid the potential DoS situation you're experiencing. Be aware that setting autodisconnect too low will reduce performance. Jeff Schmidt, MCSE, CISSP Systems Developer / Engineer The Ohio State University Extension Voice: (614) 292-0295
