Re: Really Odd TCP/IP Issue - Help!



Hi Herb;

Thanks for the reply!

Telnetting into any of the ports gives an unable to connect error.
I can't reach anything whether I use the IP address or the FQDN.
Any request always resolves to the proper IP address and then times out.
This only happens on my own site - I can reach anything and everything else
:-)
The site's been up for years so DNS entries are fully propagated.
The machine is clean and virus/malware free- it's a recent format.
The site askmarvin.ca

I can trace a route to it from a DOS prompt and I can connect with my
browser but only through my ISP's proxy (they are private internal machines).

I'm lost. I can't see any reason for this to happen at all. It makes zero
sense!

Best & Thanks;
Marvin
