Dear All,

 I am not sure whether this mail comes under here, anyway I am posting it.

I did an ASP page that send mail to the customers when they request for password.It was working fine until we had a backdoor trojan virus infection on the server.

We managed to clear the virus, but after that we noticed that the mails are being stored in the Queue folder instead of being send. IN the event viewer, we have the message like "..unable to bind to destination server..."

I have checked the IIS configuration and the Virtual SMTP Server copnfiguration, it has no changes. In fact, I did tried to re-install the SMTP virtual server : result : The mails in the queue managed to be send (5 mails outof 60)... but when i tried to restart the smtp service .. the event log had the same message displayed for all the mails that were tried to be sent out...

I have tried giving permission to the mailroot folder but still no changes. I have also tried to change the DNS settings, but still no solution.


Really hope someone can help as it has been a pending issue for nearly 2 weeks without any solution ... Thank you in advance.

Regards,
Nagesh

Hi Nagesh

Are you able to telnet on port 25 to some on these destination servers? Maybe that would help in the trouble shooting process.

Also which might be a long shot but I have had interesting experiences with viruses corrupting the TCP stack with unexplained protocol related issues. If you are running a W2K server I would sugest to try the following:

1) Make sure u got a local account with admin rights you can use
2) Uninstall TCP/IP - do not reboot
3) Delete HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\W inSock2
And HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\W inSock
4) Reboot server and reinstall TCP/IP

This would rebuild the stack.
If it was an IIS related virus maybe investigate issues sorounding the IIS metabase...

Goodluck
