I'm running Plesk 7.5.3 on Win2003 server standard. My websites work fine for about a week and then they all stop responding. When this happends I can log into the plesk control panel but I'm not sure what to check for. I go to Services Management and restart World Wide Web Publishing Service along with Plesk Name Server but that doesn't seem to do anything. I'm not sure what files check for or maybe a setting I have misconfigured. I'm having to restart the whole server to make the sites come back online. Any help would be appreciated.
