ESET Mail security for Exchange let's win2k3 hang

hello all,

Anybody else experiencing this behaviour that eset mail security for exchange v4.2.10016.0 on a win2k3 64 bit server with exchange 2007 has some hickups regarding network connectivity. Almost every day the server will not respond to pings for a couple of seconds making it unavailable. This is not at a specific time , it can happen like at 3 in the morning till very late in the evening but no more then once a day. Already having a huge list of exceptions like advised by both ms and eset and changed the setting to scan all files to common files but untill now nothing works.

Removed Eset also but then the server works fine without the hickups. :S

Anybody?

 

already found out that the problem lies in the antivurus mailserver protection. When enabled time-outs occur. But still no solution for this problem :s
