Our exchange server just started attempting to connect to every IP there is. Sniffing traffic shows that it connects to ie 131.xxx.xxx.100 then 131.xxx.xxx.101 then 131.xxx.xxx.102 etc….
only sending a few hundred bytes to each IP. Sonicwall warns us that the cache is full. Internet barely works probably because of all the simultanious connections. Ran housecall.antivirus.com and found nothing. Has anyone else seen this happen???
