I have two Exchange 2000, the Front End Server in DMZ and Back End in Private Network. All ports FE and BE are enabled I have GFI Mail Essentials 6 installed on FE Server this configuration working fine for two weeks. Today the inetinfo.exe process use the 100 percent of CPU When the Mail Essentials Analizing Agent is stopped the CPU usage down at 4% but all inbound mails are queued at Incoming folder on Mail Essentials 6 directory. When this services is started the 100% CPU usage again. This high cpu usage causes that the outbound mail are queued Any help would be apreciated Víctor Naranjo MCSE SYNERGY
