You don't just post there and wait for a reply. You read the information in that thread, follow the links, and follow the info that relates to you.
For example, do you have a firewall? Windows XP (which has a built in firewall you might not know of)? A router? All of the above? Are you on a network of some sort (school/college/uni/work/cybercafe)?
Read the info, for most people that have ident issues it is not as simple as just typing /identd on IdentHere.
Regards,
