Based on some quick research Steve Evanchik did at the lab here...
"The domain rcsb.org periodically doesn't resolve correctly on my machine:
$ nslookup.exe rcsb.org
Server: somdns01.srv.ibm.com
Address: 9.0.5.1
Name: rcsb.org
and from my Linux machine:
[EMAIL PROTECTED]:~> nslookup rcsb.org
Server: 9.0.5.1
Address: 9.0.5.1#53
Non-authoritative answer:
*** Can't find rcsb.org: No answer
However, I can get to it via the web at http://rcsb.org which is odd.
Anyway, it looks like beyond that the SRV record for rcsb.org does not exist:
[EMAIL PROTECTED]:~> host -t srv _lsid._tcp.rcsb.org
Host _lsid._tcp.rcsb.org not found: 3(NXDOMAIN)
So it appears that the LSID authority rcsb.org is no longer operational."
