i had built a wingate 6.0.4 server for NAT service, and had made user restrictions,means the PC users must open GateKeeper.exe and input their username & pwd for the auth,or they can't access the Internet. the machine works well before. but these days there is a strange thing happening: user who has been authenticated before ONE minute can't access the internet. And this user's auth item will disappear in the server "Client Activity" list. now if he reauth the GateKeeper.exe . he can access in one minute. just one minute, it would be cutted.
about the block time ,i calculated . it would be around 1 minute,almost 1"30.
god,what a strange thing ,how can i deal with it ?
