I can think of another reason for it not to work:

I've seen computers with smuggled in entries to the local HOSTS file to reroute certain addresses to skimming sites.

Try a NSLOOKUP on bill.ccbill.com. It should read like the following:

C:\Users>nslookup bill.ccbill.com
Server: dnsserver.domain
Address: 192.168.111.10

Non-authoritative answer:
Name: bill.ccbill.com
Addresses: 64.38.212.54
..........64.38.215.54

If the last part (the two addresses} look different, then check the file C:\Windows\System32\drivers\etc\hosts for any entries NOT for localhost, especially for bill.ccbill.com and remark / delete them. Then try joining again.
