    new users not displayed in Global Address list

    I had this issue also. After trying everything, I finally realized that Outlook was caching the address list. Turn caching off and everything will appear. Good luck! Karl

    OWA New Message Issue

    I've install OWA on my FE Exchange Sevrer 2000. Everything works fine except: When I start a new message, the text box in order to compose the message is not there. It is outlined in gray with x icon in the upper left hand corner. The same holds true when I try to reply to a message. Any...

    Another Apporach to blocking spam

    That's just it. It is set to the DNS Black list and spam still gets through. Why, because spammers can make up domain names.

    Another Apporach to blocking spam

    OK, there is a difference of opinion and I agree with the above. I just want to stop it at a different level. There isn't a difference between what I want to do and black listing a domain.

    Another Apporach to blocking spam

    Inform the customer, help them with their problem, once resolved allow them to deliver to me. Just by filtering does not help those whose severs that have been taken over. This spam stuff needs to end. It wastes all of our time.

    Another Apporach to blocking spam

    I am using GFI Mail Essentials to block spam. Granted it catches a lot of spam, however, there is about 10% of spam that slips through.

    Restricting RPC to a specific port

    OK - So I am in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services and \NTDS\ does not exist. Do I add this? I see a NDIS or an NTFS but not an NTDS. Please shed some more light on the correct path. Thank you, Karl

    Restricting RPC to a specific port

    Thank you. You would think that others would have this problem and that Microsoft would correct it.

    PIX, Exchange 2000, Windows 2000 in a DMZ

    OK. Thanks for your help. You pointed me in the right direction. The servers in the dmz, are they able to access the Internet? Would you please post your whole config file? I have the email flowing just fine, however, whenever I add the access list rule to allow mail to flow from the dmz to the...
