Hi Mark, If I am understanding you correctly, are you using a standard version on McAfee Corporate on your Exchange server? You do know that you have to exclude the transaction logs and exchange database scanning on most client based antivirus programs, including Symantec so that you do not corrupt them. Both Symantec, McAfee and Trend Micro have an Exchange anti-virus scanning engine designed specifically to scan an Exchange Information Store. Personally I prefer to have a Mail Gateway server scanning email for Virus's before they are delivered to the Exchange system. http://www.mirapoint.com/products/razorgate_100.shtml Postini and Bright Mail also offer hosted solutions that work well for small to medium business.

You never guess what the problem was.. and so stupid of me that I did not think of it. It means that the problem was there for a longer time than I thought. It was McAfee v8.01 Enterprise that was the bottleneck!!! I uninstalled my Symantec Corporate Edition 9.0, and installed McAfee after many people told me that it was much better than Symantec. What is your opinioun about this? I thought of it after I found the next article on the web: http://kbase.pscs.co.uk/index.php?page=index_v2&id=242&c=1 ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: jmedeiros@xxxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx
