I have a PC that, as a part of our voicemail system, sends out very short emails that let my customers know they have new, urgent, and/or fax messages. This is done through a special app that gathers TNPP data from the voicemail system, and sends it to a simple e-mailer. It has worked great for more that a year since we started the e-mail notification service. Other than an outage due to a failed firewall, this has worked non-stop for a long while....
This system now, cannot ping anything Lunarpages nor send simple emails to mercury or aquarius servers (as I can switch on the fly when one or the other have "issues" from time to time.
It cannot send e-mail whatsoever now..it just tries to connect and cannot for some reason. I cannot send email out using a regular email client from this PC (outlook express-sending to mercury server). I cannot ping any lunarpages servers, but I can ping other sites/addresses outside my netowrk just fine from this PC including my home email server, mail and smtp.comcast.net...
I can send e-mail and ping lunarpages servers from other PC's on my network (so my firewall is not the IP that may be blocked as a spammer).
The private IP of the trouble PC is 10.30.0.21 and it's MAC address is:
00-D0-B7-79-7B-30.
I can't figure what it is? ! ?
Help.
