We are getting Event ID 5719 on our Windows XP Pro SP3 clients on a Windows Server 2003 domain.
This is causing problems with access to some of our servers but most importantly it is causing our Content Management filtering device to block all Internet access for that client until the client has rebooted, or waited 30 - 45 minutes.
And the incidents are increasing.
We have tried increasing the MaxDgramBuffering value from 128 KB to 256 KB:
But it had no effect.
We tried restarting the Net Logon service on the client and when we did that we could get access to the servers the client previously couldnt get access to, but it didnt help with the Content Management device and access to the Internet, we still have to either reboot the client or wait 30 45 minutes.
