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

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...

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.

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. Spammers can easily change the from address/domain. Anyways - lets get back to the original question: I was...

Thanks, In this case helping others only helps yourself. GFI is good, but it doesn't prevent your resources from being used. Eventually, your pipe could be filled with spam. What if spammers start sending out large files to your domain as a DoS attack. Eating away at your bandwidth. The way...

It has happened twice. Two different companies called and said that they were getting bounce backs from my domain. We investigated found that there was relaying, block the relaying and now they are sending.

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.

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. After doing research on spam, I thought that I shouldn't just filter on keywords in the email or subject line. When spam is sent and caught, resources are still...

Thanks, I figured it out already.

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

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

I am trying to minimize the RPC traffic between my DMZ and Internal LAN. In Microsoft's article it says to add the following key: HKEY_LOCAL_MACHINE\CurrentControlSet\Services \NTDS\Parameters Registry Value: TCP/IP Port Value Type: REG_DWORD Value Data: (available port) When I go to...

Does anyone know of an eaiser way to enter ip address in the deny access section of IIS SMTP? Is there a file that I can open to copy and paste the ip addresses that I want to deny? Also, is there a limitation on the number of IP Addresses? I am getting spammed and would like to stop it at the...

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...

Thanks for the response. On the owa server what ip address are you using for dns? Are you using the internal lan dns servers? or are you using lmhost or hosts files? is the owa 2003 a FE/BE exchange system like 2000? I don't understand these lines, could you explain? static (inside,dmz)...

I have done this, however it does not resolve properly. The FEExchange server thinks that the BEExchange server is 192.168.20.5, as you pointed out, but the FEExchange server can only communicate to the BEExchange via 192.168.10.5 conduit. This is the issue. Is there anyone out there that is...

static mapping already creates the pointer from 10.5 <-> 20.5 and the counduit statement is an acl static (inside,dmz) 192.168.10.5 192.168.20.5 netmask 255.255.255.255 0 0 conduit permit ip host 192.168.10.5 host 192.168.10.13 Thanks

Again Thanks for the reply but these lines allows everything open. The following opens up ip between the 2 servers in the firewall I know this is wrong, I will close up the holes later. I need to make sure it works first. static (inside,dmz) 192.168.10.5 192.168.20.5 netmask 255.255.255.255 0...
