Re: socket error

It ended up with something to do with our Proxy configuration. On both the
1.1 & 2.0 boxes I had the MS Firewall Client installed. This worked fine on
the 1.1 box, but on the 2.0 box for some reason the httpwebrequest couldnt
get out. I un-installed the firewall client on the 2.0 box and it ended up
working fine? Our proxy server (isa 2004) was configured to allow all
outbound connections for both the boxes. So I dont see where the problem
was?

TIA!
